2 strokes. got to love them! they do make a shit load of power. can only imagine the powerband the old gp bikes had. got a video somewhere with onboard footage an its ridiculous. but that said. the r1s sure do fly. i done a comparison test between my mille an bro inlaws r1 from 40km/h to until i thought i better back off... no comparison. stupidly quick. but that said. id still rather my v-twin.
una r1 moderna con una rd500 vieja aunque en forma. mirar en otros videos de you tuve rd500 puestas al dia y vereis que maravillas de moto capaces de humillar a muchas modernas.
2 stroke is awesome, don't get me wrong, but a power band of 2k rpm is only fun on the track, like most people, I drive on regular roads. a 4 stroke does deliver heaps of torque, is very drivable through the city, has fuel consumption my wallet doesn't have to cry about, doesn't leave a mile of smoke behind it and does deliver close to 200 rwhp. why all the fuss?
@Renceau Yeah, my old man's bike had those on his 2 stroke, I get where you're trying to go with that, but since you didn't address any of the points I made I'm gonna have to let this slide, and ignore it.
creo que la rd no estaba en buena forma, me gustaría verla tocada como otras que se ven en algunos vídeos de you tube y veríamos realmente lo que anda una rd 500 sobretodo como mínimo hasta 200kmh estoy seguro que en aceleración fulmina a la 1000 luego ya tengo claro que una r1 alcanza hasta 280kmsh
monster douchbags will pick the r1 cause it is more popular and well known. true motorcycle lovers will choose the rz for the acceleration and the history of it. In all not many modern 4 strokes could even be compared to a rz its just to beautiful.
by the time the MUCH BIGGER engine catches up with a much older two stroke its way way over speed limits and the speeds you can safely ride at on most roads. two strokes were always dominant, they sound better, deliver power faster and are much more fun when you play with the revs. See how those wet fart harley loving idiots banned two strokes on the dirt when they got their noses rubbed in it. Give me a two-stroke yamaha any day.
Very awesome bike. I used to race an R1 and it would shit all over RG and feel safer to. And having no engine braking sucks balls. I love the old stuff. Ive got a 79 CBX 1000 and an 85 GSXR 750. Ive owned and ridden most of the 2 strokes also. But they are hands down slower, more dangerous and will fuck you up. Dont ever think the old stuff can run with the new. Nobs will always say the new stuff has no sole. Wait 10 years and see. The best become classics.
@fragglevooper you raced an R1 and you say it shit all over the RG..How would you say your CBX1000 compares to the RG500 Gamma? I already know that the RG500 would have killed your 1985 GSXR 750, because back in the mid 80's it was said that if you weren't riding an RG500 you weren't winning. Can't say the same for the overweight underpowered RZ500. Watch old vintage footage and see what was not only being raced in 1989 BUT winning, and then tell me all about what an R1 has done.
I outran the cops twice on my TDR250 back in 1990. Scary at the time but they were in Vauxhall 3.0 Senators and trying hard. Thinking back on it now, it was quite funny, 2-strokes rule and I would buy a new TDR / TZR / RD / RG again tomorrow if they still sold them!
@itscallednitrous yeah of course they both have their pros and cons, it all depends on how you ride and how you do your maintenance, 2 strokes are just cooler period.
bring two strokes back cos as far as im concerned the sooner this o-zone fucks off the better i live in england and we need more sunshine so guys gets your strokers out and remember to add lots of nasty 2 stroke oil to your tanks!!!
2 strokes engines are superior but extremely expensive for oils and i agree with1980 aankrah that they polute the air BUT there is always a but there are some 4 strokes engines that they are really wild and angry for example KTM 620 my friend got this the racing one and trust me within 3 seconds u were already flying! I WILL ALWAYS LOVE 2 STROKES
I'm not asking about how strong it would be..Tell me what would weigh less. Answer that simple question you simple minded fool. If you don't want to answer that question try this one. If Kawasaki used Steel instead of Aluminum on any of their modern sport bikes, would the bike weigh more or less. You have no hope you fucking idiot.
@86GAMMA Who are you talking to? Do you think that aluminum framed bike would be heavier or lighter? RZV is about 20lb lighter than the RZ with a steel frame The only real difference, as far as weight saving is concerned is the aluminum frame as compared to the steel frame. I think we agree with each other on that. Am I right? Of course my answer to your question is the steel framed bike would weigh more. If you had the same bike with the same frame, the steel framed bike would weigh more
I'll clear up the Ducati trellis frame after you answer me this. If ducati built the exact same trellis frame in both steel and aluminum, what would weigh less? I'm giving you a chance to redeem yourself. Take all the time you need.
@86GAMMA nice way to make a retard out of yourself, and pretty much prove my point. if ducati make the exact same trellis frame out of aluminum it would fail under the weight of the bike, which is why aluminum frames end up weighing the same, or in some cases even heavier than steel frames, which has been proven many times on the scales. however, i fully expect you to be too stupid to understand all of this, and anticipate your nonsense reply.
@86GAMMA The aluminum frame would weigh less of course. However for it to be as strong as the steel frame and actually support the bike they would have to use a lot more aluminum which would increase the weight. However, even with that said it would still be lighter. Aluminum weighs less than half what steel does, and is 60% as strong. Therefore using enough aluminum to be at 100% the strength of the steel frame you it would still be roughly 20% lighter.
There is no way that the RD500 in stock trim can touch an R1. As a matter of fact I just sold mine because it was tank and way too slow. It had flashy bodywork for the time but that's about it for that bike.
pound for pound 2 strokes dominate period. 4 jokes would be slow if it wasnt for their displacement. they need 1000cc's to beat a 2 stroke with 500cc's. 4 strokes are weak WEAK!!!!!!!!!! YOU HEAR ME!!! 2 strokes forever!!!! all these guys you see now in days think they're all bad ass with their 1000s. fuck man i wish yamaha would build a 500cc 2t just to shut all these 4 joke guys up. if the old rd500 can do that to an r1, now imagine something with 2010 technology? 2t>4t forever.
@TUNEDBYRET I hear what u say.I love 2T, but they have ports, some of the burn stroke is lost to exhaust scavenging, by design they must consume oil, their rings wear out prematurely etc. Survival of the fittest is at work here. 2Ts, like the dinosaurs, had their time.As a mechanic I see their wonder. However,try an electric bike. CrAzY.Electric motors-MORE POWER per kilo than a combustion engine could ever have-although no way as alluring as the 2 Ts.Anyway, hail to their once reign. King RD
@9Barry009 as a mechanic would you say that a 2 stroke is cheaper and easier to fix than a 4t? also lets say Yamaha brought back the 500cc 2 stroke, how would that compete against the modern 1 liter bikes of today.
2 stroke all the way, even though they break all the time. I love the sound and how they kill anything around the streets on acceleration. 4T for long distances - 2T around the streets
You can have these awesome machines in America they are just expensive (but expensive everywhere now). If you keep your eyes open, a lot of US titled RZ500s and RG500s have been for sale recently with the downturn. Always great to shut up the R1 fanatics when you actually sit them on an RG500 (or ride with them).
10 years ago, Chrysler's Joe Goulart was singing the praises of the two-stroke engine as an automotive powerplant. His dream, however, couldn't pass muster with the EPA. As a result, the automotive two-stroke engine died.
Environmental concerns dogged the recreational two-stroke, as well. After years of doing nothing, the EPA set strict pollution limits for recreational vehicles (personal water craft, snowmobiles, etc.), which called into question the two-stroke's continued viability. Fortunately, no one told George Broughton, director of Engineering, Boats and Outboard Engines Div for Bombardier He created the Evinrude E-TEC family of two-strokes; engines that are clean and darn-near worry free.

He seems un-willing to even consider anything outside his own frame of reference or beliefs system. Oh well, they come in all shapes and sizes don't they.
Hahaha, I won't get any support from a bunch of two stroke fans looking at this video and I don't really care. I'd give ya the keys to every vehicle I own if they ever make a 2 stroke car again, or a two stroke that is magically cleaner then a 4. You can keep thinking what you want, I'll laugh when they dont even make 2 stroke weedeaters anymore....or has that already happened? lol. Maybe you can call a few more friends to agree with you on youtube so you look cool, doesn't bother me.
2T are elady made that are cleaner than 4T. They are having direct injection.
Arschgeiger. Anyways, I opened this account because I was reading your garbage and knew that you were wrong and felt I had to say someting. You are an idiot. Vollbekloppt.
Or even make another account? LOL CluadiaBohm created his account today, just to post on this....it's probabbly just you anyways. God youre killing me man.
YOu don't lubricate the combustion chamber you lubricate the cylinder walls and the bearings. Meter so little oil that it is all burned (clean burn) or keep the oil completely seperate from combustion and the problem is solved.
Okay see heres what you arent getting, sure you meter in a tiny amount of oil so its all burned, well yeah, but that oil is still BURNED. That tiny burnt oil produces emissions. Over hundreds of thousands of cycles it adds up to a ton of emissions. Imagine if you just lit a quart of 2 stroke oil on fire how much smoke it would make? Well thats pretty much what you are doing over a longer period of time. And the cylinder walls ARE the combustion chamber so im not sure where you are going there.
Unburnt hydrocarbons cause the problems, not fully burned. What stores sell now and what thy have under development are two different things. It's no claim I worked for Cosworth in Wellingborough Northamptonshire. If you know anything about engines, then you will have heard of Cosworth.
Far from a kid I have almost 20 years on you and more experience in automotive engineering than you can even dream about. Learn what you are talking about and then speak. I really am done with you this time.
Oh please, like every person I've ever met on youtube your "much older and wiser" yet for some reason you spend all your time copying and pasting and arguing on the internet? I know what I'm talking about so I'll continue to speak. What stores sell and what's under development is like what works and what works in theory, it really only matters what works doesn't it? Maybe when Ford makes that engine you can work for them when they have to rebuild it every 5000 miles since you know so much.
I have a life, I'm getting paid to argue with you right now actually. I suppose it varies on the shape of the combustion chamber itself if you would include the cylinder walls or not, but that really doesn't matter. I thought you were done arguing? I don't see how you can argue that a 2 stroke will ever be as clean, quiet, and reliable long term as a 4 stroke. Its just not possible when you have to use some sort of oil injection.
I don't care where you claim to have worked. YOU are quite simply wrong, go into any bike dealership and see how many 2 smokers are for sale, hardly even any dirtbikes anymore. Youre just a kid with a 2 stroke dirtbike/scooter that thinks he knows what hes talking about, I've been rebuilding 2 shit topends for years now and listening to your "2 stroke is coming back" story is a great way to pass time at work.
Hey pollywagger how do you come to that conclusion? Take your cock out of your cats ass and read my comments carefully or better yet, have someone read them to you. I said there is no way that an RD/RZ500 would take an R1. I love two strokes but not this piece of junk. The RZ500 was a flop from the day it was released and was almost never used in club racing...know why? TOO FUCKING HEAVY BAD BRAKES AND NOT ENOUGH POWER...Do your research and then reply. If the looks please you that's fair.
im a 2 stroke fenatic owning 2 rz350's a stroker banshee and a fzr1000, but in a race with equal experienced riders im pretty sure a r1 would smoke a rd500 in every aspect
That's right in ever aspect! Who in their right mind thinks that an overweight underpowered bike can compete with an R1. That is an insult to Yamaha engineering to say the least.
NO doubt, the RD is 25 year old technology and the R1 is hot off the press, plus it has a 100% capacity advantage. Compared to 750cc bikes and more importantly 500cc 4 strokes of its day and it walked all over them, even though it was underpowered and overweight when compared to the RG500 Gamma
Forgetting the fact that the RD is 20 years older and only the half of the engine capacity...
This RD upthere im sure is a street version, with the half of the power. The GP versions of the 500's where hitting 190Mph. And in the video you can already see wich bike accelerates faster.
So...the 500s i truly belive it would have good chances of winning in a race circuit.
And the video is a good proof that the 2 stroke is much more cappable racer than the 4stroke.
Of course it accelerates faster, I never denied that. Its a 2 stroke!
But saying that the RD would beat the R1 on a race, based only in acceleration, is not true. You answered me, but you still didnt mention the ability to make corners.
This comment has received too many negative votesshow
The R1 will crush an RD500 in cornering braking top speed acceleration and has the reliability to boot. These bikes aren't in the same class...Only an idiot that knows nothing about motorcycles would suggest that an RD500 with 80 Hp on the crank (68) to the wheel could compete with an R1 with let's say a conservative 120 on the wheel..You must be in fantasy land where 125's eat busas on the dragstrip if you believe that.
The RD500 was junk in 1985 and that's why no one raced it in club races.
Put the RD500 engine in the R1 Chasis? The R1 Will destroy this overweight underpowered bike in any aspect of racing including acceleration..Think about it.
R1 has way more horsepower
R1 has a superior chasis
R1 is lighter
why would anyone think that the RD500 can compete with an R1 when in fact the bike was garbage in the mid 80's. Watch any mid 80's club race and look at what was being raced..Nobody that wanted to win rode an RD500. The real beast was the RG500 Gamma by Suzuki!
I actually made research and found out that the biggest weakness of the RD 500 was the chassis, which was made of steel. I saw a French garagist next to where I live who managed to get an RD500 engine into his Aprilia RS 250 chassis. He can now fully exploit the engine, and is still rocking any 4 stroke on the 3 first gears.
He is now looking for a RG gamma engine, because of it's wonderfull stock 98hp and two stroke awesomeness, but RD 500 is still a grand prix inspired motorbike.
i really wonder if the companies like honda yamaha produce a 500cc 2 stroke bike with 2009 tecnology ( 60hp at 125cc ) what it could happen ??? the 2 strokes will always be the tecnology of speed!!!
@bonebreaker27 You want a 2 stroke with 2009 technology you can buy a (TSS RS500GP) It has a 500cc yamaha banshee engine with 90 degree crankshaft setup.
@bonebreaker27 not sure about 60hp out of a 125...the legal limit is 33hp upto the age of 20 or 21...thats for the U.K though im not to sure about anywhere else
Yeah but that wont be a standard RD500 engine. It'll be tuned to fuck and need rebuilding all the time the R1 is a much more road friendly bike and much more useable. Two strokes are dead and never comming back. Nice to see them still running though
@p0ngl3 2 strokes are on the way back already. With Ditech direct injection. It means they burn cleaner than a carburated 4 stroke, use hardly any oil and produce 60% more power for any given capacity. Ford is looking at them for cars with 1 liter engines producing over 200hp and enough torque to pull a mid size car quickly and easily. Imagine that engine tuned for a bike, less torque more HP, less weight and with power valves on the exhaust and traction control, manageable power delivery.
Anyone who thinks the two stroke is coming back is in total denial. As fun as they are, dirty 2 stroke motors are dead, and certainly wont be used in any car lol
Ditech is a load of crap used to sell old polluting things to people as "environmentally friendly" Anything that burns oil is of course going to make more pollution then something that doesn't, common sense.
You are quite simply wrong. DiTech Aprilia, burn cleaner than 4 strokes in the same class, get better mpg and produce more power. You need to look the stuff up. ford is experimenting with direct injection 2 strokes because they use less gas, produce more power, pollute less and are cheaper to produce. If they weren't car manufacturers wouldn't be working with them. Look it up.
You will believe anything anyone feeds you, I'd bet you own that stupid "DiTech" scooter. Explain to me how a engine that by design BURNS OIL and gas can make less emissions then something that only burns gas? Given the same emissions controls it's impossible, just think about it it's only logical. I have found nothing about Ford experimenting with a 2 stroke, and even if they were they will never make anything of it. It's impossible for a 2 stroke to not be dirty, just like "clean coal"
I believe the results of testing. Rotary engines burn oil in exactly the same way as 2 strokes, they are fuel injection now too. Th 1.3 liter Mazda RX8 engines produces 247hp from 1.3 liters, and is cleaner than 4 strokes engines. When you use the right materials inject the oil at exactly the right time and so little of it that you get complete (i.e. clean) combustion then while lubricating at the same time it burns cleaner than a 4 stroke. I do not have an Aprilia scooter
You obviously didn't look for the Ford 2 stroke stuff at all or not hard enough. It's there to be found. Very soon 2 strokes will not need any lubricating oil in the combustion charge at all. The advent of ceramics make mean it isn't required. What makes 2 strokes dirty is incomplete combustion and older 2 strokes that had wide engineering tolerances. That is no longer the case. I am not going to waste my time arguing with you, you will be proved wrong eventually.
The Brighton Multi-Cylinder Camless Engine is a Ricardo-developped in-line 3 cylinder camless GDI research engine. The four independently controlled hydraulically actuated valves per cylinder allow for research into advanced engine cycles and combustion modes.
It demonstrated outstanding 2 stroke performance of 150 Nm/l at 1000 rpm and 230 Nm/l at 2500 rpm thanks to its innovative combustion chamber. The concept of the engine relies on using the traditional cylinder poppet valves found commonly in 4 stroke engines to be used in 2 stroke mode also by switching to a different valve opening frequency. Unique valve, fuel and air handling control strategies ensure a smooth mode switch and good scavenging in 2 stroke operation.
the engine is to keep the top of the combustion chamber free
of engine parts, except the injector, a relatively
simple electro-hydraulic variable compression ratio mechanism is integrated to the combustion chamber. A variable geometry turbocharger will be used and it, along
with the valve timing and compression ratio, will be controlled by the engine management system based on engine speed and load to optimize performance while meeting emissions requirements
Way to cut and paste a bunch of crap you don't really understand. First off, don't bring the rotary into this, I had a 94 FD and I'm not going to even begin to believe that you have any idea of how the oil metering system on that car works. 2nd, nothing you have posted proves anything, it just proves you know how to paste shit. The combustion chamber must be lubricated and in a two stroke the only time to do so is during the actual combustion, there is no way around friction.
I understand it just fine. The fact that I cut and pasted it doesn't make it any less true and doesn't make you right. There are 2 ways you can lubricate, you can use compression of the fuel air mix outside of the crankcase, meaning sump oil will lubricate the cylinder and big and little end bearings
continued or you can meter so finely as DiTech does that you get complete combustion. I used to work for Cosworth in Northamptonshire in England, I know full well what I am talking about, unlike you. I am done arguing with you. You are quite simply wrong.
The Split-Cycle by Scuderi uses an additional piston to compress air destined for the combustion chamber replicating the crankcase compression technique used by a conventional 2 stroke engine, but excluding polluting lubrication-oil from the air-fuel mixture. Combined with timed valves to control the in of compressed air and outflow of exhaust, the new engine is not only superior to existing 2 strokes, but that it is also more efficient and cleaner than the average 4-stroke engine. Nuff said?
None of that stuff actually works other then in theory, and googling "ford 2 stroke" or 2 cycle brings up nothing related so it certainly must not be a big deal. 2 stroke is dead, period. It will certainly never be used on larger daily use engines and its already being phased out on everything else.
the only thokg that the 4 strokes do all this years is to steal tecnology from the 2 strokes . but even though the old 2 strokes are the tecnology of speed and power ... and power means acceleration not top speed
bonebreaker, "power means accelleration not top speed". It's true that aerodynamics play a huge part in ultimate top speed. But wind resistance builds up at the square of the speed, so for any given bike, it takes 4 times the HP to do the ton as it does to do 50 mph, 9 times the 50 figure power to do 150, & 16 times the power to do 200. Which is why there are no 200 mph standard production bikes.
Still so many years later, with so many technology improvements and the double of displacement...The R1 still CANT beat the old RD. In fact the R1 even still looses.
I think th R1 lost only a few meters at the start and pulled it back later The R1 will win all day long Its got a longer powerband higher top speed more torque blah blah etc etc But who cares
Dude the RD probably made more pollution in this run then the R1 makes in a year, and the R1 will probably last literally over 10 time longer. Not to mention anyone who has ridden a streetbike or anyone that has a basic understanding of high school physics could tell you these were not equal riders. If they were the RD500 would have been destroyed.
on a dragrace an rg500 makes the 400m in 9 sec and a gsxr1000 with turbo makes it in over 9.5 so the old 2 strokes can stiil beat the poor 4 strokes!!!
In a drag race the rg500 (fastest going 2stroke made) does the 1/4 mile in 11.2 seconds. Gsxr 1000 with NO turbo will do the 1/4 mile in 10.3 seconds which is about 14 bike lengths. Now to be fair the RG500 is Not a drag bike but a track bike, and a great track bike at that..A GSXR 1000 with a turbo could easily run in the 9's...Compare apples to apples there bonebreaker!
The part you seem to be missing is that aluminum has to be 50% thicker than steel for the same strength for any given form. That uses up a lot of the weight advantage, but even with that said, for the same strength the aluminum frame is still slightly lightler.
If you write something on a social website, like youtube, it by default becomes the business of everyone using that site.
you did account for a part of the weight but it seems you forgot to account for the fact that aluminum can't deal with repeated stress like steel can. this doesnt matter on race bikes that stay on groomed tracks and get frames replaced any time its needed, but on production street bikes that have to be able to cope with pot holes and rail road tracks and squids dropping wheelies, well that eats up most if not all of the weight advantage.
I said All race bikes have aluminum frames, all of them, bar none. Density of Aluminum is 2.7 g/cm3
Density of steel is 7.75 g/cm3
And in response to the comment in my e-mail that isn't showing up here. Yes I know that 20lb differences on GP bikes would be huge and the weight differences in GP are a couple of pounds.
But we aren't really talking GP bikes are we. A difference of a few pounds on two street bikes, doesn't amount to much, even 20 or 30 doesn't amount to a whole lot.
even a slightly less powerfull 2 stroke can beat a 4 stroke on acceleration because of the way it fires and draws air but the 4 stroke may use its power and torque better at top speed pulling large gears 2 strokes make you smile more
its a pity they stopped producing 2 strokes engines. if they produce them still they could have over200 hp on the 500 cc and i am not mention for the gp racing bikes!
2 strokes are inherently more powerful for any given capacity. Every downward stroke of the piston on a 2 stroke is under power (being blown down by an explosion of fuel air mix) it is every other downward stroke on a 4 stroke, ergo the 2 is at first glance twice as powerful or 500cc 2 stroke = 1000cc 4 stroke. It isn't quite that simple though, the volumetric efficiency of a 2 stroke is not as good as a 4. so, a 500cc 2 stroke is about 50% more powerful than the 500cc 4 stroke.
Type in Gary Cowan Yamaha 250 and watch part 1 or part 2 of the race....This was back in the late 80's and notice what bikes are being raced..NOT 1 RD500/RZ500! But RC30 made the grid and So did the RG500...and no its not a 250 race but the 250 was fighting all the way to the finish..Ask yourself why with all these different bikes, why there was no RD500! It was too heavy and slow!
Ou no!! Ou no!! Is that R1 eating dust and smoke from the RD? hehehe. I cant imagine how miserable a guy who just spent thousands of dolars in an R1 beliving that that was the fastest bike ever must feel. LIKE AN ASHOLE
lol, the r1 caught up in the end, just better acceleration of a two stroke obviously =D, i bet the 2009 r1 would give the rd500 a run for its money, 182hp =D
yep, my dad used to have one, custom paint, micron exhausts, tuned to 76hp proffesionally, unfortunatley he had to sell it in a tight financial time, but hes getting another one soon! his old one was an '82, it was the first 350lc in banbury lol
The rd is an old bike, with an old design and with only 500 cc, wich is still a small engine and carbs, and the r1 is a modern 1000cc bike and much better equiped technologically speaking, fuel injection and everythng you want.
And however the R1 still eated dust and smoke from the good old RD.
2 strokes. got to love them! they do make a shit load of power. can only imagine the powerband the old gp bikes had. got a video somewhere with onboard footage an its ridiculous. but that said. the r1s sure do fly. i done a comparison test between my mille an bro inlaws r1 from 40km/h to until i thought i better back off... no comparison. stupidly quick. but that said. id still rather my v-twin.

It's not all about peak power, it's also about how fast you get to that peak power.
Power doesn't say everything about the performance of a bike.
A tuned two stroke pisses and shit all over any four stroke because of it's tendency to get to the power much faster than a complicated four stroke.
i.e.
Rev a four stroke from idle to red zone
Rev a two stroke from idle to red zone
...
Yeah, I knew that.

2 stroke is awesome, don't get me wrong, but a power band of 2k rpm is only fun on the track, like most people, I drive on regular roads. a 4 stroke does deliver heaps of torque, is very drivable through the city, has fuel consumption my wallet doesn't have to cry about, doesn't leave a mile of smoke behind it and does deliver close to 200 rwhp. why all the fuss?

Very awesome bike. I used to race an R1 and it would shit all over RG and feel safer to. And having no engine braking sucks balls. I love the old stuff. Ive got a 79 CBX 1000 and an 85 GSXR 750. Ive owned and ridden most of the 2 strokes also. But they are hands down slower, more dangerous and will fuck you up. Dont ever think the old stuff can run with the new. Nobs will always say the new stuff has no sole. Wait 10 years and see. The best become classics.

@fragglevooper you raced an R1 and you say it shit all over the RG..How would you say your CBX1000 compares to the RG500 Gamma? I already know that the RG500 would have killed your 1985 GSXR 750, because back in the mid 80's it was said that if you weren't riding an RG500 you weren't winning. Can't say the same for the overweight underpowered RZ500. Watch old vintage footage and see what was not only being raced in 1989 BUT winning, and then tell me all about what an R1 has done.

The argument between 2T and 4T cannot be won..
Both have Pro's and Con's..
2T Engines:
(+) Accelerate quicker, are lighter, and also have less moving parts..
(-) Pollute more, need 2T oil(expensive), use more fuel (vs 4T)
4T Engines:
(+) Don't burn oil in the chamber, more economical, smoother, Tuning Capability
(-) More Moving parts, Heavier, Slower Acceleration (vs 2t)
You go for what YOU like best. Only a fool would try to win an argument that cannot be won!

@86GAMMA Who are you talking to? Do you think that aluminum framed bike would be heavier or lighter? RZV is about 20lb lighter than the RZ with a steel frame The only real difference, as far as weight saving is concerned is the aluminum frame as compared to the steel frame. I think we agree with each other on that. Am I right? Of course my answer to your question is the steel framed bike would weigh more. If you had the same bike with the same frame, the steel framed bike would weigh more

86GAMMA 1 year ago
@86GAMMA nice way to make a retard out of yourself, and pretty much prove my point. if ducati make the exact same trellis frame out of aluminum it would fail under the weight of the bike, which is why aluminum frames end up weighing the same, or in some cases even heavier than steel frames, which has been proven many times on the scales. however, i fully expect you to be too stupid to understand all of this, and anticipate your nonsense reply.
Brian500R 10 months ago
@86GAMMA The aluminum frame would weigh less of course. However for it to be as strong as the steel frame and actually support the bike they would have to use a lot more aluminum which would increase the weight. However, even with that said it would still be lighter. Aluminum weighs less than half what steel does, and is 60% as strong. Therefore using enough aluminum to be at 100% the strength of the steel frame you it would still be roughly 20% lighter.

There is no way that the RD500 in stock trim can touch an R1. As a matter of fact I just sold mine because it was tank and way too slow. It had flashy bodywork for the time but that's about it for that bike.

@TUNEDBYRET I hear what u say.I love 2T, but they have ports, some of the burn stroke is lost to exhaust scavenging, by design they must consume oil, their rings wear out prematurely etc. Survival of the fittest is at work here. 2Ts, like the dinosaurs, had their time.As a mechanic I see their wonder.

YOu don't lubricate the combustion chamber you lubricate the cylinder walls and the bearings. Meter so little oil that it is all burned (clean burn) or keep the oil completely seperate from combustion and the problem is solved.
Scootertuner1000 2 years ago
Okay see heres what you arent getting, sure you meter in a tiny amount of oil so its all burned, well yeah, but that oil is still BURNED. That tiny burnt oil produces emissions. Over hundreds of thousands of cycles it adds up to a ton of emissions. Imagine if you just lit a quart of 2 stroke oil on fire how much smoke it would make? Well thats pretty much what you are doing over a longer period of time. And the cylinder walls ARE the combustion chamber so im not sure where you are going there.
raptorlp03 2 years ago

That's right in ever aspect! Who in their right mind thinks that an overweight underpowered bike can compete with an R1. That is an insult to Yamaha engineering to say the least.

NO doubt, the RD is 25 year old technology and the R1 is hot off the press, plus it has a 100% capacity advantage. Compared to 750cc bikes and more importantly 500cc 4 strokes of its day and it walked all over them, even though it was underpowered and overweight when compared to the RG500 Gamma
Scootertuner1000 2 years ago
Obviously the RD accelerates much harder than a R1. Amazing! Then, of course it has less top speed...but come on! Its a 500cc against a 1000cc!!
And in a race, i think the RD has big chances to win against a R1...because in a race acceleration is what counts...

So...the 500s i truly belive it would have good chances of winning in a race circuit.
And the video is a good proof that the 2 stroke is much more cappable racer than the 4stroke.

The R1 will crush an RD500 in cornering braking top speed acceleration and has the reliability to boot.

He can now fully exploit the engine, and is still rocking any 4 stroke on the 3 first gears.

p0ngl3 2 years ago
@p0ngl3 2 strokes are on the way back already. With Ditech direct injection. It means they burn cleaner than a carburated 4 stroke, use hardly any oil and produce 60% more power for any given capacity. Ford is looking at them for cars with 1 liter engines producing over 200hp and enough torque to pull a mid size car quickly and easily. Imagine that engine tuned for a bike, less torque more HP, less weight and with power valves on the exhaust and traction control, manageable power delivery.
Scootertuner1000 2 years ago 3
Anyone who thinks the two stroke is coming back is in total denial. As fun as they are, dirty 2 stroke motors are dead, and certainly wont be used in any car lol
Ditech is a load of crap used to sell old polluting things to people as "environmentally friendly" Anything that burns oil is of course going to make more pollution then something that doesn't, common sense.
raptorlp03 2 years ago
You are quite simply wrong. DiTech Aprilia, burn cleaner than 4 strokes in the same class, get better mpg and produce more power. You need to look the stuff up. ford is experimenting with direct injection 2 strokes because they use less gas, produce more power, pollute less and are cheaper to produce. If they weren't car manufacturers wouldn't be working with them. Look it up.
Scootertuner1000 2 years ago
You will believe anything anyone feeds you, I'd bet you own that stupid "DiTech" scooter. Explain to me how a engine that by design BURNS OIL and gas can make less emissions then something that only burns gas? Given the same emissions controls it's impossible, just think about it it's only logical. I have found nothing about Ford experimenting with a 2 stroke, and even if they were they will never make anything of it. It's impossible for a 2 stroke to not be dirty, just like "clean coal"
raptorlp03 2 years ago
I believe the results of testing. Rotary engines burn oil in exactly the same way as 2 strokes, they are fuel injection now too. Th 1.3 liter Mazda RX8 engines produces 247hp from 1.3 liters, and is cleaner than 4 strokes engines. When you use the right materials inject the oil at exactly the right time and so little of it that you get complete (i.e. clean) combustion then while lubricating at the same time it burns cleaner than a 4 stroke. I do not have an Aprilia scooter
Scootertuner1000 2 years ago
You obviously didn't look for the Ford 2 stroke stuff at all or not hard enough. It's there to be found. Very soon 2 strokes will not need any lubricating oil in the combustion charge at all. The advent of ceramics make mean it isn't required. What makes 2 strokes dirty is incomplete combustion and older 2 strokes that had wide engineering tolerances. That is no longer the case. I am not going to waste my time arguing with you, you will be proved wrong eventually.
Scootertuner1000 2 years ago
The Brighton Multi-Cylinder Camless Engine is a Ricardo-developped in-line 3 cylinder camless GDI research engine. The four independently controlled hydraulically actuated valves per cylinder allow for research into advanced engine cycles and combustion modes.
Scootertuner1000 2 years ago
It demonstrated outstanding 2 stroke performance of 150 Nm/l at 1000 rpm and 230 Nm/l at 2500 rpm thanks to its innovative combustion chamber. The concept of the engine relies on using the traditional cylinder poppet valves found commonly in 4 stroke engines to be used in 2 stroke mode also by switching to a different valve opening frequency. Unique valve, fuel and air handling control strategies ensure a smooth mode switch and good scavenging in 2 stroke operation.
Scootertuner1000 2 years ago
The all aluminum turbocharged 2-stroke compression ignition engine. The
engine basic geometries and operating parameters are shown
in Tables 2 and 3. Rotary valves with variable timing are fitted on the side of the cylinder bore and chain driven by the crankshaft.
Scootertuner1000 2 years ago
fitting the valves to the side of
the engine is to keep the top of the combustion chamber free
of engine parts, except the injector, a relatively
simple electro-hydraulic variable compression ratio mechanism is integrated to the combustion chamber. A variable geometry turbocharger will be used and it, along
with the valve timing and compression ratio, will be controlled by the engine management system based on engine speed and load to optimize performance while meeting emissions requirements
Scootertuner1000 2 years ago
Way to cut and paste a bunch of crap you don't really understand. First off, don't bring the rotary into this, I had a 94 FD and I'm not going to even begin to believe that you have any idea of how the oil metering system on that car works. 2nd, nothing you have posted proves anything, it just proves you know how to paste shit. The combustion chamber must be lubricated and in a two stroke the only time to do so is during the actual combustion, there is no way around friction.
raptorlp03 2 years ago
I understand it just fine. The fact that I cut and pasted it doesn't make it any less true and doesn't make you right. There are 2 ways you can lubricate, you can use compression of the fuel air mix outside of the crankcase, meaning sump oil will lubricate the cylinder and big and little end bearings
Scootertuner1000 2 years ago
continued or you can meter so finely as DiTech does that you get complete combustion. I used to work for Cosworth in Northamptonshire in England, I know full well what I am talking about, unlike you. I am done arguing with you. You are quite simply wrong.
Scootertuner1000 2 years ago
The Split-Cycle by Scuderi uses an additional piston to compress air destined for the combustion chamber replicating the crankcase compression technique used by a conventional 2 stroke engine, but excluding polluting lubrication-oil from the air-fuel mixture. Combined with timed valves to control the in of compressed air and outflow of exhaust, the new engine is not only superior to existing 2 strokes, but that it is also more efficient and cleaner than the average 4-stroke engine. Nuff said?
Scootertuner1000 2 years ago
None of that stuff actually works other then in theory, and googling "ford 2 stroke" or 2 cycle brings up nothing related so it certainly must not be a big deal. 2 stroke is dead, period. It will certainly never be used on larger daily use engines and its already being phased out on everything else.

But wind resistance builds up at the square of the speed, so for any given bike, it takes 4 times the HP to do the ton as it does to do 50 mph, 9 times the 50 figure power to do 150, & 16 times the power to do 200. Which is why there are no 200 mph standard production bikes.

wrong, it builds at the cube of the speed.

just because i ve seen the rg500 run at 9.2 secs the 1/4 mile and the gsxr turbo in 9.7

Still so many years later, with so many technology improvements and the double of displacement...The R1 still CANT beat the old RD. In fact the R1 even still looses.
Simply the 2 strokes rule.

hahaha YEAHH! HELL YEAH with 2-strokes

This proves nothing
I think th R1 lost only a few meters at the start and pulled it back later The R1 will win all day long Its got a longer powerband higher top speed more torque blah blah etc etc But who cares
Both bikes have their place
lumpybruisychickeny1 2 years ago
Well...For you this proves nothing.
For many others, like me, this proves that the 2 strokes still cant be beaten.
The RD acelerates FASTER inspite of being about 20 years older and having only the half of displacement. (like that werent a big disadvantage)
A shame.

Fake ! I had an RD 500 47X and have now an R1 RN04. The R1 is much faster in acc and top anyway. R1 first gear is already 110 km/h !

Dude the RD probably made more pollution in this run then the R1 makes in a year, and the R1 will probably last literally over 10 time longer. Not to mention anyone who has ridden a streetbike or anyone that has a basic understanding of high school physics could tell you these were not equal riders. If they were the RD500 would have been destroyed.

on a dragrace an rg500 makes the 400m in 9 sec and a gsxr1000 with turbo makes it in over 9.5 so the old 2 strokes can stiil beat the poor 4 strokes!!!
bonebreaker27 2 years ago
In a drag race the rg500 (fastest going 2stroke made) does the 1/4 mile in 11.2 seconds. Gsxr 1000 with NO turbo will do the 1/4 mile in 10.3 seconds which is about 14 bike lengths. Now to be fair the RG500 is Not a drag bike but a track bike, and a great track bike at that..A GSXR 1000 with a turbo could easily run in the 9's...Compare apples to apples there bonebreaker!

Brian and 6String, you both need to shut the fuck up. Both of you only have half the facts each.
You both need to go back to school. Jesus fucking christ, grow up, grow a pair each and stop acting like fucking kids.

The part you seem to be missing is that aluminum has to be 50% thicker than steel for the same strength for any given form. That uses up a lot of the weight advantage, but even with that said, for the same strength the aluminum frame is still slightly lightler.
If you write something on a social website, like youtube, it by default becomes the business of everyone using that site.
Grow a fucking pair of balls you cunt.

you did account for a part of the weight but it seems you forgot to account for the fact that aluminum can't deal with repeated stress like steel can. this doesnt matter on race bikes that stay on groomed tracks and get frames replaced any time its needed, but on production street bikes that have to be able to cope with pot holes and rail road tracks and squids dropping wheelies, well that eats up most if not all of the weight advantage.
Brian500R 2 years ago
I said All race bikes have aluminum frames, all of them, bar none. Density of Aluminum is 2.7 g/cm3
Density of steel is 7.75 g/cm3
And in response to the comment in my e-mail that isn't showing up here. Yes I know that 20lb differences on GP bikes would be huge and the weight differences in GP are a couple of pounds.
But we aren't really talking GP bikes are we. A difference of a few pounds on two street bikes, doesn't amount to much, even 20 or 30 doesn't amount to a whole lot.

even a slightly less powerfull 2 stroke can beat a 4 stroke on acceleration because of the way it fires and draws air but the 4 stroke may use its power and torque better at top speed pulling large gears 2 strokes make you smile more

mfuji00001 2 years ago
its a pity they stopped producing 2 strokes engines. if they produce them still they could have over200 hp on the 500 cc and i am not mention for the gp racing bikes!
bonebreaker27 2 years ago 2
2 strokes are inherently more powerful for any given capacity. Every downward stroke of the piston on a 2 stroke is under power (being blown down by an explosion of fuel air mix) it is every other downward stroke on a 4 stroke, ergo the 2 is at first glance twice as powerful or 500cc 2 stroke = 1000cc 4 stroke. It isn't quite that simple though, the volumetric efficiency of a 2 stroke is not as good as a 4. so, a 500cc 2 stroke is about 50% more powerful than the 500cc 4 stroke.

Type in Gary Cowan Yamaha 250 and watch part 1 or part 2 of the race....This was back in the late 80's and notice what bikes are being raced..NOT 1 RD500/RZ500! But RC30 made the grid and So did the RG500...and no its not a 250 race but the 250 was fighting all the way to the finish..Ask yourself why with all these different bikes, why there was no RD500! It was too heavy and slow!

lol, the r1 caught up in the end, just better acceleration of a two stroke obviously =D, i bet the 2009 r1 would give the rd500 a run for its money, 182hp =D

Nothing on the fucking planet can accelerate like those two stroke bikes.
And not even so many years later they can be supperated by the monster 4 stroke racing bikes! How amazing...

The rd is an old bike, with an old design and with only 500 cc, wich is still a small engine and carbs, and the r1 is a modern 1000cc bike and much better equiped technologically speaking, fuel injection and everythng you want.
And however the R1 still eated dust and smoke from the good old RD.
Just patetic buhahaha!!!!!!!
