Radial engine motorcycle

[HoGBerG95]

small tank, BIIIIG enginge :D

[lunageologist]

@HoGBerG95 Small Tank + BIIIG engine = Short rides (mostly to gas stations.... LOL) I wonder what the mileage on that thing really is. I love getting 50+ MPG on my bike, that thing has to get something in the range of 2. Amazing bike though, Amazing engine. I am sOOOOOOOOOOO jealous!

[jaratt85]

Ive seen a radial powered bike before this.. Jesse James made on for a guy, he mounted the engine side to side tho. Theres actually a video on jay lenos garage's site of it under motorcycles.. go fig.

[celticbobb]

posing pouch....tiny tank no use whater-so-evar!

[lmogden1]

what cc and horse power

[greatwhitenorth112]

SUPER throttle response 

[MikeWebbsDead]

jay leno has one made by jesse james that looks nicer

this one looks nicer, the radial is pointed forward

[SLINGSHOTandMOLOTOWS]

This is one of the coolest chopper I seen. One of the most innovating builds out there. How ever if the engine blows up it may hurt or kill but thats life.

[crocodile2006]

Is that a 6 Cylinder motor or 7 cylinder?

[Ecelleon]

@crocodile2006 Probably a 7, radial engines typically have an odd number of cylinders.

[crocodile2006]

HOLY..... FUCK

[twohandtap]

Its a bit scary having that piston pumping on your balls :D

[mindeloman]

It's not often you see a motorcycle with an engine that has a cam ring and not a shaft.

[samacem]

[MagicGonza91]

it looks cool, but the posterior cilinders may not be perfectly refrigerated, that gets into a durability problem

[jaydotosh]

wow.... imagine kick-starting that XD!

[RTic83]

Im about to buy one....

[illusions581]

@nastytheboy i think it must be a 110hp engine

[NASTYTHEBOY]

what kind of pwoer does a radial put out!? and what king of drive train do you use!?

[Flies2FLL]

The advantages of a radial engine are extremely low weight for the displacement and awesome cooling capability....while not having the inherent liability of a liquid cooling system. Disadvantages? They don't rev very well, due to the heavy crankshaft and "master and slave" connecting rod system, they create a lot of drag due to the large frontal area, and the complex and difficult to lubricate "ring" cam.

Really, packaging is the biggest liability of this engine design.

[TheAmericanUhate]

@Flies2FLL Liquid cooling systems is a "disadvantage"? Wow, someone better let every current vehicle manufacturer on the market with in the last 20 years know! Last I heard liquid cooling was suppose to be a lot better then air cooling but hey some random guy (you) on youtube said it so the rest of the world must all be wrong!

[thobeta]

orgasm :!

[rcguy4373]

balls to the wall

[coolster131]

very nice. what will it get on gas? hahaha

[vigi86]

... damn, this is .... woah!!! just porn!!

[sadajpe]

まだ売ってるかな〜？これ。

[Robinpus]

eargasm <3

[hughc11123456789]

i saw a guy who mounted a 9 cylinder radial with the prop shaft facing towards the rear and he had to have a 90 degree gear box specially made at great expense.

personally i think what you have done looks fantastic... just not sure about the size of the petrol tank and the amount of fuel that beast of an engine would eat up

[crankthatdawg]

quarter throttle

[lucabadue]

motocycle with a airplane sound ! =)

[Jdub121686]

Well, a Vtwin is just 2 cylinders of a radial, lol

[DiazRemington]

all makes and models - ** freemotorcyclemanuals . net

[christiaanajcronje]

Yes it looks cool but there is a reason you dont see too many of them.... Great build though

[Rezaroth]

thank you for the vid guys :)

but may I know whats a radial engin?

[8giang8]

I'd buy this bike if I wanted to become a woman. Just jump on and ride it hard around the twisties and your an instant woman minus the tits.

[sidwinder99]

show its riding

[whatzupa]

That's cool.

[ser15gio73]

impresionante esta moto

[plazzax]

wow.., insane, i saw this in a custom magazine for a couple of months ago, or a year ago, and it looked awesome :)

[talowe87]

throttle response is nasty.

[pixicato69]

so what fuck practical its awesome

[quadbravo]

love it.

[saiello2061]

Yeah nice, but how long can you run a radial engine before heat problems...? Won't make for a very practical ride.. ;o)

[Ogi4a]

Wow the response is insane.

[agav8r802]

I've got approx 7,000 hrs of time with a radial on the nose of a machine. In that 7,000 hrs I have witnessed several catostophic failures of a radial.

Don't think I'd want one between my legs......LOL,

Sweet Bike though

[zeker111]

@agav8r802

what kind of faillures? obviously not fatal ones, cause you wouldn't be telling this :)

[Sprebound]

@agav8r802 amen

[MisterWillie060]

@agav8r802 You must have been flyin an ag cat or a 301 or maybe a 400 gallon thrush?

[agav8r802]

@MisterWillie060

All of the above :)) (good call)

[toranamunter]

@agav8r802 are you a gayviator or an aviator in the 802? :-)

[agav8r802]

@toranamunter

Aviator for sure.

Everyone here at HogAir is a bit intolerant of turd burglars.....LMAO

[toranamunter]

@agav8r802 LOL :-)

[EarlRausch]

@agav8r802

Man that's crazy.

I have heard stories primarily during WW2 of an engine getting hit and loosing a jug or two, and the engine would still run. For how long?

I am sure that loss of oil would be severe.

Are the radials smooth compared to an opposed cylinder engine ?.

I had to research how they made those radials. odd cylinder and all. Quite interesting.

I would love to fly in a plane with a radial.

Thanks for your comment.

[colin340]

@agav8r802 just curious what goes wrong with them?

[oiseautempete]

@agav8r802

This engine is the Australian Rotec engine: he's VERY reliable...on a airplane! , but it was never think for installation in a bike, so the cooling isn't correct...

In the past the only bike built in numbers with a "radial" * engine was the German Megola (in 1922)

* in real the engine from the megola was a rotary direct drive install IN the forward wheel)

[Cuinnton3]

@oiseautempete keep in mind that a radial engine works excellently as an air cooled engine for the following reasons.

1.instead of 4 cylinders trying to create 110 horsepower. Much like the water cooled Rotax or AIR COOLED Jabiru 2200 (which has cooling problems), the R2800 spreads that power over 7 cylinders, not over 4. the engine is capable of producing much more power

2.optimal surface area for air cooling

So with the relatively low air flow on a bike compared to a plane it is not a concern

[oiseautempete]

@Cuinnton3

OK: i never say that the cooling, on a aircraft, isn't good, i know this type of engines: i'm a early aircraft mecanic, work on Wright R3350 18cyl dual cyclone turbo compound (Neptune P2V7 French Navy) and a bit knowledge from the SNECMA/Bristol Hercules 14 cyl sleeve valve engine (Noratlas 2501)... :-)

[badVWbug]

WHAT! That is the sickest idea for a chopper I've ever seen. I love it, awesome! :)

[Mitsugejl]

Guess the length of this clip is equal the amount of fuel available in that tiny tank - cool bike though, thats new :)

[MOISES0683]

is the gas tank will be enough to go around of the corner?

[isleofit]

Er . . . WOW !!

[mrrabbit257]

engine would have more even cooling if u put it lenghtwise and bike would look epic bizarre and scary in front, awesome job anyway :]

[starbuck680]

next to the video click on more info & you'll see a link to a bike built by Jesse James that is like you describe. I don't think it's as nice as this one though

[SparkinNparkin]

Holy f***! Best bike I've seen

[danrichards23]

thats just weird. id like to see u try to ride it. i imagine it idles at 100mph with those rpms.

[LateNightCable]

Wonder what make of engine that is, Wright, P&W? etc. It's cool, but that looks like waaaaay too much power for any motorcycle, let alone a custom cruiser. Like a rocket engine on a Model-T.

[sinofallsinners]

i totally agree...even thought i would love to see some one drive a model t with a 7000hp top fuel dragster engine...haha

[poimarr]

dont all cruisers have more power then they can handle is that not the point

[LateNightCable]

I don't know if that's the point, but most factory cruisers make less than 100 horsepower. I reckon this engine makes a lot more than that.

[rayunseitig]

Amazing.

[CockpumpVideo]

Amazing

[starbuck680]

awesome looking bike but hearing about having to pull the plugs on it if it sits for a while, that would be too much of a pain in the ass for me. 110hp? 7 cylinders & that's all it puts out?

[justforever96]

110hp, but at what torque? Radials are torquey as fuck.

[MyMIXmedia]

Revs quicker than a top fuel drag car.

[TroyaE117]

I often wondered why the ground crew rotated the big aircraft radial engines by hand before starting them.

[temelorego157]

fly ?

[Cheevoah]

NOTE: This is a "radial" NOT a "rotary". There is a very big difference. Do not get the terminology mixed up. YES it is a radial. YES it does have cylinders. It is a seven cylinder radial that produces 110hp. Wavernr was completely right in pointing out the fact the engine must be "pulled through" (pilot perlance) before starting to clear any oil that has collected in the bottom cylinders. Longer time parked = remove bottom sparkplugs. Otherwise a hydraulic lock could ruin the engine.

[toranacar]

What do you mean pulled through? Do you mean turning the engine over without starting? Very interesting.

Nice job, very unique.

[justforever96]

@toranacar- Yes, "pulled through" is to turn the engine over before starting. You'll see crew men turning the prop of a radial-engined aiplane before they start it. Like he said, it is important because the oil can collect in the bottom cylinders of a radial when it sits. I believe that it also has something to do with getting the flow through the oil pump started, since it drives off of the crankshaft. That would make sure that oil was flowing to the engine from the moment it starts.

[Ilovetypography]

Great idea! This thing will have hell alot of torque!

[W1ldSm1le]

wow this thing looks totally badass.

[TroyaE117]

Cooling?

[jsdm14]

Air

[Tigre30]

you are right! ha

[justforever96]

Radials are almost always air cooled engines. Makes sense, since the cylinders spread away from each other unlike an inline, so air can flow through better.

[stinkingdog101]

needs a relly slow loping idle....that is one of the major seeling aspects of the large VTwin Cycles.

[wavernr]

Cool idead! But seems like it would be a pain to have to drop the lower plugs to drain the oil out of the cylinders before you start it all the time.

[londonoverground]

wasnt there any early australian radial where the cyclinders actually rotated? or am i talking shit? please let me know

[Bamchucknorris]

your thinking of a rotary enigne.

raidal enignes turn the crankshaft while rotary engines such as the bently br-2 have spinning cylenders and a stationary crankshaft.

[londonoverground]

aha thanks. do you reckon it would be possible to fit a bike with a rotary and have a belt attached to the crankcase somehow?

[Bamchucknorris]

its possible, yes it is, as long as you can weld a gear for the belt on the crank case and put some kind of guard around the spinning enigne.

[69sexymonk69]

no, a rotary engine has rotors, no cylinders and a spinning crankshaft

[Bamchucknorris]

your thinking of a wankel roatry. there are rotary engines with pistons such as the bently br-2. yourtube "bently br-2" you will see

[swinkyuk]

That's a type of rotary engine yes, such as the wankel, but the older type of radialy configured piston engines where the cylinders spin on a stationary crank are also called rotary engines.

[slothmandela]

how long before you have to fill the tank lol 1mile?

[tinchosatan]

how many cylinders it have??

[justforever96]

It has seven cylinders. Radials are almost always odd-numbered, or they vibrate (worse than they already do!). You can count the cylinders easy enough; each cylinder has a pair of those silver rods running in front of it, so just count sets of two, or count and then divide by two. Those are the valve pushrods, and there is 14 of them, one intake and one exhaust valve per cylinder.

[BruceCarbon]

This is a very cool idea :D

[Dieselpowerkid]

must be a burnout from hell

[SpencahD]

COOL!!

[devja71]

now that's what i call throttle-response. great job guys

[LOLDISNEYLAND]

Very very very very nice. radial engines: from plane to motorbike :D

[jeffandmissymello]

west coast choppers has one with the engine mounted facing forwards check it on their website

[starbuck680]

@jeffandmissymello this bike is way nice than that one

[redcarsarasota]

I love this country! People come up with the coolest shit!

[mitchellberry]

where the hell can you even find a radial engine aside from in an old ww2 junkyard or something

[JGMagoo]

that is a brand-new Rotax radial engine sold for use in small home-built experimental airplanes. Most of the WWII aircraft radials were nearly 6-feet in diameter.

[lotonpark]

I think this is an Australian Rotec R2800 engine, not a Rotax.

[justforever96]

LOL, R-2800 as in 2800cc's maybe. Usually when someone says "R-2800" their talking about the Pratt & Whitney Double Wasp radial. That was a whole different animal. The "-2800" in that name meant "2800 cubic inches displacement". As in Big Fucking Engine. 2,000 hp enough for ya? Too bad it weighs like 2,300 lbs and is like 4'5" in diameter! (And it's twin-rowed, so good luck fitting it between your legs!)

[hcannonii]

how many mpg?

[green724x4]

u mean gallons per mile

[hcannonii]

yes, how many?

[markthreemillion]

might as well kiss the cylinders that arent facing the wind goodbye haha

[jacobsjam]

Theoretically heat should dissipate throughout the entire engine therefore cooling the cylinders not facing the wind.

[mandaltby]

hats off boys

really cool

is it possible to find an engine 1/2 that size, it seems it would work fine. 300 ci is still 3 harleys

[TommyWylie]

Jacobs make small radial engines I believe. (757 ci, 12.3 litres). It could be one of those. Bigger than your average Harley.

[bigorangetrucker]

and way cooler too...

[1reginol]

i bet a woman could get off ridding that. hell im a guy and i think i just did

[fangus503]

damn that things got some pickup

[graybermann]

Behave, P&W aeros are the size of that garage. Sounds nice though.

[charliedip]

Unique; to say the least.

[787Bisurdaddy]

I do like the styling of this bike better than the Jesse James bike, but I have to assume that James' bike is probably better for heat dissipation.

Either way, doesn't matter, I love this bike. It's awesome.

[BarefootBASE]

I'm still not sure,i know the block isn't spinning , but there is a crankshaft and flywheel which would but as you said being a radial it would be pretty much perfectly balanced ?i don't know what your talking about with the Jesse James bike i'll have to have a search for that.

This bike probebly is fine,for all i know it may even be better for stability?i have been told some old BMW type bikes with the north south facing engines do turn weird because of that configuration.

Anyway it is cool.

[787Bisurdaddy]

"i don't know what your talking about with the Jesse James bike i'll have to have a search for that."

There's a link in the video description.

[bobwatters]

yeah but with radial engines the oil settles to the down facing cylinders you have to turn the motor over run it threw the stages before acualy starting it

[BarefootBASE]

I bet that thing will be difficult to ride , the centrivical forces will be crazy, lean left or right off centre and it will want to lay over . I really hope not but it's like spinning a huge disc between your arms and trying to turn it , i can't think of the scientific name for it but ...... gyroscopics ????

Rather than being a little kid and putting a thumbs down if you know better reply why , i'd like to know how they over came the problem?

[787Bisurdaddy]

"the centrivical forces will be crazy, lean left or right off centre and it will want to lay over"

The engine itself is not spinning, it's not creating any centripetal forces. The pistons inside the cylinders are simply moving up and down ("inward" and "outward" from the center of the engine). It really wouldn't be any different than any other piston engine, other than the weight being spread out.

[bobwatters]

their would be no cerntrifical force like 787Bisurdaddy said

plus even if their was crazy centrifical force it would not want to lay over or even lean at all thats what it does when the wheel on a motorcycle spin fast they creat cintrificul force thats the only reason that you get a bike back up after draggin your knees

[auto4union]

The engine doesn`t have to turn to effect handling ! The Yamaha Moto GP bike has a backward spinning crankshaft for this very reason !!

[787Bisurdaddy]

I understand that; that's why I said that it's not creating any centripetal forces and that it's basically the same as any other piston engine.

The engine will obviously place torque on the chassis which is something that can be seen by revving just about any car engine while standing in front of it, but that's hardly going to matter at all on a bike like this.

[justforever96]

Yeah, but the crankshaft is spinning inside, and you could almost say the pistons are "spinning" as well, since the stroke pattern move radially around the engine. He's right about the gyroscope thing, only he's wrong too, since it would be an issue if the engine was mounted 90deg to the frame. Much of it is airfoils and prop weight, but even a regular radial in an airplane tries to pull it to one side or the other. WWI rotaries were vicious for that, and just the crank spinning creates force.

[Tomasonifrancesco]

oh yes....I love it!!

[Noxangelus82]

Thats better than sex.

[toranacar]

Thats sick

The power come on instantaniously lol

SICK

[lapoltba]

I think i peed a little

[MilesB1975]

Oh sorry, its a radial, not a rotary. I thought the cylinders were spinning around for a second.

[MilesB1975]

Amazing work, Biggles would be proud, just make sure your fly is zipped up before starting it..

Could be very nasty.

[3abdellatiff74]

fuckin sexy

[Motorflieger]

Should be a Rotec R2800- so 110HP like just said. This engine looks similar to that engine in a Biplane at the airport I'm flying at.

[justforever96]

Well, a lot of radials look "similar" to each other, unless you know what you're looking for.

[SRQshark]

thats insane

[hammerogod]

I am amazed.

Nice job of incorporating that into a fairly nice looking frame.

Is the engine a Rotec R2800?

[shabatize]

if your wondering y its leaking oil...lol ask a steerman piolet why he wears googles..... hey at least the pushrod tuebs leak just like the motor that would otherwise be in there

[justforever96]

Umm...a Steerman pilot also kinda wears goggles to keep the 100mph wind out of his eyes. But yes, any radial plane without a cowling on the engine will spit some oil. Hell, radials mileage is listed in both gallons of fuel per hour, and quarts of oil! LOL, not very PC, but still cool. Better than an old Liberty V-12, with it's old skool open valvetrain. It's called a "total loss" oiling system, where it's not designed to keep all the oil inside and recircle it, it just feeds oil from a tank!

[kidjr27]

How fast????

[adambus77]

insane !

[scott93257]

God bless...That is soo freaking cool.. I have always been fascinated with a radial engine...Always.. And now to see it in a Bike...Oh Shit that's the ULTIMATE

[777worldliner]

nice!!!!!!!

[DoubleIntruder]

That looks pretty evil!

But in a good way..

I bet it's pretty scary to ride..

[Zelle10]

i'd so love to ride the bike !

[hieronymusbsch]

who gives a fuck how many miles he does on it?

Its a fucking sicko seven cylinder radial engine bike and that makes it cool, so stop bitching and go watch the fucking simpsons you morons, more your intellectual capacity.....

[wayne205stevens]

cool!

[Weltar]

how many horse power?

[GGigabiteM]

If it's a Rotec R2800, then it has 110 HP.

[iceman050890]

That bike is so fast, it will rip the soul out of you

[carlitossqban]

sad to see a radial designed for aircraft being but on a bike.

[mturgeon2]

That's SICK how fast this thing revs up!

[muskokatone]

vera vera cool!!!

[blue03r6]

I tell ya what fb2800, email him and find out the miles he put on it so far...I bet its under 1000.

my bikes all see at least 12k a year.

[fb2800]

No one really cares that your ho hum factory bike has done 12k miles this year, boring! What we are trying to determine here is whether or not this JRL custom bike is a "trailer queen" or not. I'd say the drags at Sturgis and the occasional cruise down the hwy is enough to shake your unfair tag! 1 mile on this bike would equal 1 million on your Honda scooter!

Put up a u-tube vid of you bike doing something and lets watch the hit counter freeze.

[vikkiandbradley07]

thats fucking sick sounds as good as it looks!!!!!!!!!!!!!!!!

[GeneralSirDouglasMcA]

I'd like to have me a radial powered bike. I love the look of radial engines on airplanes, so it'd be nice to have one on a bike as well. :D

[dkracerman]

tons of responce

[R28R36]

The heating/cooling issue keeps cropping up.

Trust me there is no overheating problem!

The chopper has been operational for over a year now and is being extensively used. The heads have not melted yet and as the engine runs just warm they will never overheat!

Now look out for more exciting projects under way with radial powered bikes....

Regards - "On the drawing board"

The engine runs cool!

[luvscats69]

dayum!!

[sweet60chevy]

fan-freakin-tastic

[LuvMyGT500]

I agree with the last comment!! That is SICK!!!
