Two stroke power

[vellotrol]

THIS IS VERY GOOD EXAMPLE OF HOW FUCKING UP THE NICE

SOUND OF A MOTORCYCLE RACING VIDEO WITH FUCKING MUSIC.

[ricibiribicci]

what was this race?

[houeah]

@ricibiribicci

probably assen 2002

[ricibiribicci]

@houeah ok, tnx



[richardhcarter]

Well the rub is not that the 4T bikes could even hang with the 2Ts. They just kept adding displacement to the 4Ts until they were just too fast. It was simply political, nothing to do with which was a better race bike. The only true comparison would be equal displacement bikes on the same track.

[khronoGTA]

When racing was getting on a bike and drive with two balls as fast as you can, not go full throttle and let traction control win for you...

[Marlever357]

Most of us know that the old stroker races were much more exciting and entertaining to watch but all the tea in China will not bring them back.Really miss those old machines.

[motogpfan46rossi]

Rossi's lap times dropped well over 1 full second with about 4 laps laft and his top speeds went from 235kph up to 255kph and he swallowed barros and won the race with about 4 laps to go. U could easily see the difference in how quickly the 2 stroke get to full lean

[motogpfan46rossi]

Equal size engines the 2 stroke is much more powerful. Even a 600cc 4 stroke moto2 or world supersport bike makes 140hp or less. The 2 stroke 500's made about 190 hp.

[MetricHotrodsdotcom]

@motogpfan46rossi i heard that the 500s two strokes made 230hp in 2003.

[Syndrome991]

@MetricHotrodsdotcom aprilia rs3 cube, 500 2 stroke, hp between 240 and 260hp :D

[motogpfan46rossi]

I just recently re- watched this GP on motogp.com . It is always fun to watch races from 02 to see the 2stroke vs 4 stroke racing on track together the sad thing is that despite the 2 stroke being 30 or so lbs lighter they still can't (couldn't ) match the 990's on the straights. Vr rode behind barros almost the entire race then all of a sudden he blew by him on the straight so fast it was obvious that vr was just saying close for the fans . Engines of equal displacement the 2 stroke Is much mo

[ZeroKenshin]

/watch?v=RSsxOQ2Dq_U for more of the race =)

[mi2tom]

Fit a 500cc two stroke with the latest tech and traction control and put the bike between the leg of the lousiest rider, I bet you, that he will take over everybody very easily, These stupid manufacturer honda is the one started this stupid 4 stroke nonsense. Why must honda have a lot of say in motogp? Next year there will be no more 125cc 2 stroke and will be replace with 250cc 4 bangers, Thanks to honda motherfuckers... I'M still using a honda NSR150 2stroke and will always use it!

[brandex62]

bring back the 2 stroke racing and fuck the government and there stupid environment cock sucking laws ... they don't think of the environment when it comes to war and h' bomb testing do they. look how long the oil fires burned in the oil war throwing black acrid toxic smoke up in to the sky for months,,, they are cock suckers.

[MrJaggedman]

To all you arguing that 4 strokes are better, please know your facts. 2 stroke will always without a doubt be faster than 4 strokes. Yes 4 strokes are great and older 2 strokes may seem slower than newer 4 strokes. Not the case. Technology has been developing in the 4 stroke region and the reason they are phasing out 2 strokes is because of the environment, fuck the government and its laws! If 2 strokes were still in production and allowed to be improved, I can guarantee they would sell more.

[VR46Nico]

Oh yeah, the old days...

This is Assen 2002

[VELOCI46]

Honda NSR 500 West Pons the most beautiful bike in modern motoGP...:)

[ED209ISBACK]

How can anyone NOT like 2 strokes are you kidding?, hell i like 4 strokes too but 2 strokes are just too much fun. Anyone that restricts themselves to 4 strokes is seriously missing out on the other half of the FUN!

[FEGTTTSDH]

two stroke forever

[eamh2002]

Nowadays a ktm exc-f has the same 30-40hour piston change period, and less power than a 250 2-stroke.

And the titanium valves go bad very easily with any dirt going inside the engine.

[lebickmeck]

I would like to see how a evolved 500 two stroke would compete with an 800 four stroke. The 800 have about 220? hp with 145 kg a 500 should have 230? hp with 131 kg, but will be more difficult to ride, and will eat more tires(harder compound) I think tractioncontrol will make the 500 a lot easier to ride and less tire comsuming, compered to the old ones.

[BBGBITW]

Two stroke is still out there and being evolved (fuel injection, valve vontrol, low emissions), but it's not so very much informed about. It could again be the engine technology of choise for the fastest bikes, but two strokes is so "old" and "climate unfriendly" etc etc

[bonebreaker27]

the 4 strokes will never catch the power of a 2 stroke because the 2 strokes have torgue in all range of the rpm and they accelerate more powerfull than the slow 4 strokers

[freaka523]

@bonebreaker27 Surely you're joking?!?

[bonebreaker27]

no frieng i am not

nsr 500 repsol 240hp 98 model mick doohans bike was the faster bike ever driven

[hermitette]

Nope, the 1998 NSR500 made 180 horsepower, down from 190 horsepower the previous year because of new unleaded fuel regulations. They had to run less compression with unleaded fuel to control detonation and so, power dropped. The fastest recorded speed for the two strokes was just over 200mph from Shinichi Itoh's fuel injected NSR in 1994 at Hockenheim. The 4 stroke Honda RCVs immediately went over 205mph in 2002 and were making over 220 horsepower. They have since gotten even faster.

[bonebreaker27]

my friend you can read the hondas book history with the 100 best bikes ever and the wikipedia about the nsr500 engines and then we shall talk again. and one more thing what would you think would run the 1/4 mile faster the nsr500 or the rc211v ??

[z0ltanz0ltan]

@bonebreaker27 Surely the RC211V.

[bonebreaker27]

xaxaxaxa nothing on earth can beat the acceleration of the nsr consider that the 2 strokes starts with 2nd gear only and the reason its obvious.....

[z0ltanz0ltan]

Even for a 2-stroke fanboi, this smacks of extreme stupidity! Either that or you are being obnoxious! I am one of the biggest fans of the 2-stroke motor and use a Yamaha 2-stroke myself and I just love the NSR 500 but there is not way you can compare a 990cc or even 800cc MotoGP 4-stroke machine with a 500cc 2-stroke machine. It's not how much power that the motor generates but HOW that power is delivered to the tires that makes all the difference. Key word - power band.

[bonebreaker27]

then you should know that 1 hp of a 2 stroke is equal to a 1.5 hp of 4 stroke so a 200hp 2 stroke accelerates equal to a 300 hp 4 stroke and the most powerfull rcv had 250 hp so.....not a chance for the poor 4 sroke....and as for now the 125cc produce 60 hp so the 500 could produce over 240 hp

[z0ltanz0ltan]

That's bullshit. Mathematically (and purely theoretically), the equation is this: For the same cubic capacity, a 2-stroke motor will make around 1.5 times the power of a 4-stroke motor. I HP = 1HP, in any context. Moreover, the 500cc machines were often de-tuned to around 180-190 BHP in order to make them rideable, never mind the theoretical maximum limit. You may like to see the whole 2002 MotoGP season which had 500cc 2-strokers battle it out with the 990cc 4-strokers. Very interesting.

[bonebreaker27]

maybe your knowledge about mechanology is too short. but anyway the 2 strokes were abandonned because the rules had to promote the 4 strokes and one more thing they stopped the evolution on the 2 strokes because they were undrivable and the riders had accidents because of the hisidings .

[z0ltanz0ltan]

Funny how I support my case with facts and figures while you are clearly just trolling around. I'll waste my time no more on your retarded statements. Just one suggestion though - get your concepts straightened out. I hear Wikipedia is a good place to start. Peace!

[bonebreaker27]

you are right the facts shows the truth.... 60hp from 125cc 09 year . and as you said something for the wikipedia just read the previous comments and then talk... about the honda nsr 500 history .. and when you are about to open your mouth again please read your lessons first ...

[bonebreaker27]

@z0ltanz0ltan all the first riders prefered the 4 stroke because the stopped the evolution on the 2 strokes and gave the previous year bikes to the teams who would race with the 2 strokes because of the low budget... the 2 stroke had more over power that no rider could ever use it, when they pull the full throtle the bike started to make wheelies and must keep it down on the 2 wheels for maximum acceleration so the only reason that 2 strokes lost is because of this extrordinary p

[bonebreaker27]

Απάντηση σε αυτό το βίντεο... power that the engine has and it makes it so dificult to ride

[DigitaLCha0s1]

@z0ltanz0ltan well the 250cc 2 strokes were only about 3-4 seconds slower than the 800cc 4 strokes gp bikes.

[z0ltanz0ltan]

@DigitaLCha0s1

True. Remember though that for many years the Sachsenring actually saw faster 250's than 500's. It all boils down to the weight and power distribution to the tires. Even otherwise, 3-4 seconds per lap is still an insane amount of difference on the track. Over a 30 lap race that would amount to a staggering 2 minutes of time difference! Plus, if you compare 800cc and 500cc lap times, you can see that the state of the art has indeed progressed in MotoGP!

[z0ltanz0ltan]

@hermitette Picture this now - a 1000cc Two Stroke motor. Now, go to your chair and rock about in deafening humbling silence.

[bonebreaker27]

@hermitette the big bang engine of that year maybe had 180hp doohan requested of the screamer engine because claimed that he could handle it .

[laimunwai]

MOTOR GP 125+250+GP also is 2stroke???

[EJ25RUN]

This was 2002 and the WEST NSR500 was the best NSR of all time relative to lap times. Barros wasn't too shabby either. Remember that when they finally gave him the RC211V, he won some races and made Rossi think.

[fenafa]

Si lo hace Rossi tenemos el adelantamiento hasta en la sopa.

[ricibiribicci]

what is the year?

[Bally46]

2003 i think is 1st year of the 990's

[ricibiribicci]

but the sound il like a 2 stroke..... maybe they aren't 990, maybe they are 500's

[sambob104]

It was the first year,

and not all teams had 990 bikes.

some still used the 2 strokeers

[joschibruder]

where is the nice 2 stroke sound?

[minimaldirection]

just great bike...

[binokoda]

In this video, who has manufactured Barros' Bike/Engine?

[danharry35]

i used to race britsh 125 gp, we changed a piston every day, 40 miles worth of use, crack every 2 meetings !!!!!!

[jamiebridges123]

Actually, dominatus84 is speaking sense.

I have an RS125 and that requires a new piston every 4999 miles (8000KM)

[Robban88Nor]

Dominatus84: Please find me a 4-stroke RACING engine with a 30.000-50.000km piston life! A real 2-stroke engine changes pistons about as often as a 4-stroke would do valve adjustments and that amounts to about the same here where I live. Given the fact that you change pistons yourself, but send the 4-stroke away for valve adjustments. And given the fact that 2-strokes kick ass, I can't see why you are so eager to defend 4-strokes? They are great engines, just not as great as 2-strokes.

[vellotrol]

@Robban88Nor

You said it all brother!

Two strokes rules, not to mention

the incredible sound it makes.

[mindfreak3121992]

2 strokes were more dangerous aswell coz the riders used to push it to its max and that used to sometimes lock u p the engine and make nasty crashes! the 4 strokes are way safer

[wantedlonewolf]

2 Stroke forever!!! by far the supperior engine!

and who the fuck cares about danger??

the only people that think about the danger of the "Bike" when riding it should not be allowed to ride bikes ... there made to have fun not fill you with fear

saying that get on a big 2 stroke and you will come back shaking and white as a ghost .... everytime!

but if you cannot hanlde it, yes it makes it dangerous... just get a bike you can handle

[dominatus84]

too bad you can only run 1000km on one piston lol

four stroke has much longer piston life. about 30.000 to 50.000

[wantedlonewolf]

why would you care about spending £200 every 6 months on something you love doing!

i know i dont

[dominatus84]

you mean buying new pistons? new pistons cost more than 200 over here....

[wantedlonewolf]

i mean british pounds its diferent curency i imagine ... over here its about £120 for weisco piston and rings then any bairings that might need replacing and new gaskets costing about £30-£40

[dominatus84]

isn't it bearings? or is that american?

yeah, i understand currency, i meant 200 pounds ;)

[butcherChrist]

I have 58,000 on my 1975 gt750, original pistons, still going strong. I've only needed to replace the rings once in the 20k+ miles that I've been riding it. I'm pretty obsessive about maintenance though. Not all 2strokes are prone to breakage.

[dominatus84]

i know, but those racing engines don't really have good mileage.

gt750 is a nice bike :)

[Pergiacomo]

This is absolutely not true.

In GP motorbikes, even 4 strokes engines changes pistons very very often.

[bonebreaker27]

the 2 strokes was and will be forever the tecnology of speed the poor 4 strokes are just too slow!!!!

[mrf34]

everybody knows that the two strokes were faster than the four strokes in the corners, and that was due to the four strokes being heavier, nothing to do with power. Put that NSR500 on a straight line alongside the RC211V and you'll see which one is more powerfull.

[rotaxkivi]

build a 990cc 2 stroke, and put it next to a rc211v in a straight line. See which one is more powerful.

[1990SimS]

@rotaxkivi they have built a 800cc 2 stroke

[TheMachRider]

@rotaxkivi and see which won can win races :)

2-strokes were awesome but they really were a handful, even for the best riders in the world.

[Lexinho90]

@rotaxkivi that would be a dream to watch. a 1000 cc two stroke! so powerful would that be!

[freaka523]

@mrf34 I'm a little late on this, but agreed. Rossi was fooling around with Barros anyway, he got a lot of flak for this race because when he decided to finally go, he blasted by Barros like he wasn't even moving and gapped him instantly.

[dominatus84]

lol two stroke...

it's like walking a mile on 2 legs, but they're much shorter..

btw, it messes up the environment

[dominatus84]

(instead of on one leg)

[dggfhdfghdf]

oh ya, a bunch of guys on the weekend can ruin the enviroment, lol!! what a joke!!! you should stop shitting, and farting,

and driving, better stop eating 2.

[dominatus84]

four stroke is much cooler

[kx3kx3]

??? with all those non-essentials extra parts I wouldn't say 4 strokes are cooler!

[dominatus84]

Did you ever work on a 4-stroke and got it working right?

It's a little more work, and after that it runs better than any 2-stroke would.

Oh, and they need less motor repairs, lower wear & tear.

But my main concern is the environment, 4-stroke runs much cleaner. Especially with injection :)

[kx3kx3]

I guess you had a bad experience or feelings about 2 stroke... no matter what motorbike I tried the best feel I got

was on 2 stroke engines. All the bike I had, from big KLR to GIXXER to RZ and RM motocross, needed the same maintenance/care. Anyways, when you love your bike;)

don't tell me modern 450 cross cost less and are more reliable than 2 stroke!!

To me, it's all about the feel because no cold fact will tell if one is better than the other... wait.....power to weight ratio maybe lol

[vspec2wrx]

I agree with you. And i love how easy two strokes are to work on you only need to be slightly mechanically mided to rebuild a two stroke.

[Maverick9010]

Le 2 tempi hanno solo pregi...spettacolarità,potenza­ ,ripresa....difetti guidabilità

[bibbipilota]

wooooooooow GREAT!!!

[microape]

The 2 stroke 500's had potential of 240-250 hp, but they limited them for being too wild.

[txakaiki]

does anybody know which music sounds at video?

[pipacs74]

Tschaikowsky, Nutcraker.

[Zibonk]

perfect..!! love two stroke and 500cc ..

[an4rew]

it goes alot like the new 800s

[alessiofin]

durante quel sorpasso ero li davanti nelle trbune ad assen...correva l'anno 2oo2.......

[esquemaroto]

alex barros es el mejor!!

[Metal190W]

YEAHHHH, love the 500cc

[revrsleeker]

that wasn't power...it was the lighter two strokes agility...the 500' two stroke was way down on power against the 990 four strokes...190bhp, at best, versus a conservative 230bhp in '02 and 10 kilos lighter. Barros got his chance later in year on the 990 but he still left honda
