Radial Engine Motorcycles

Mototrcycles with radial engine. JRL cycles and Psycho Engine Indonesia. - The perfect work! Compilation with technical description.
I thank all motorcycle fans who contributed to my channel with their videos and motorcycles.

[@kalleklp7291]

They are complicated to build, service and maintain...they are expensive like hell..but they are also awesome and cool. Each a piece of mechanical art..

[@quantumleap4023]

The fact it works at all is really cool!

[@kalleklp7291]

@@quantumleap4023 Yup..! However the ignition timing is crucial for it to run smoothly...if at all. :)

[@blasthead1722]

I realize that these bikes were created primarily for the novelty appeal and thats great. I'd still love to see some performance stats on these machines

[@ryanmccloskey4292]

110 hp, 160 ft-lbs of torque, theoretical top speed of 227, and drinks 5.6 gallons of fuel an hour. From an article I just read

[@InnocuousApe]

That seems suspiciously low for an aircraft/tank engine which could make anywhere from 400-1700 horsepower.

[@punman5392]

I cannot imagine sitting on that first bike and not burning my right leg on the exhaust

[@wtkern]

Asbestos pants, anyone?

[@thomasodetinape4180]

@lahokc59 instant jerky, lol

[@Devildog9972]

Why would you imagine yourself standing still? Imagine throttling up to 150+ with more to go. Uffff, my weenie wiggled!

[@bushpoo]

Youd be fine

[@hayes2147]

Ouch

[@916fanatic1]

With that super small gas tank if you did a full throttle run it would be empty in 30 seconds.

[@Korsfestelse]

After a few blips of the throttle it sounded like it emptied!

[@scnl707]

Vertical radial engine : can i put a propeller and it can be a heli😂😂

[@neuzdost1939]

That makes no sense

[@bodeine454]

Love em! I wanna see some HP and torque numbers! 👍

[@johnbell2100]

That seat looks real comfortable

[@jeffwalker9122]

I love watching these engines on pulling tractors! Pure awesomeness!

[@wuzihuzi]

Just a guess they wouldn't really be built for the torque being aviation engines.

[@connorewers478]

@@wuzihuzi oh buddy ud be suprised

[@aaronjaben7913]

bike at 2:40 is a masterpiece

[@gertnood]

Motorcycles or other ground-based vehicles are a good place to use available Rotec radials, after a few scares folks are losing confidence in them as aircraft powerplants.

[@briankimmell7960]

Thank god builders like this exist!

[@muhammadihsan6734]

Hey i am from indonesia... This is best modified and psychoengine indonesia🤟🤩

[@privategramcracker01]

Imagine a 2 stroke radial. A man can dream...

[@GhostOfDamned]

Oh boy, you just gave me a idea

[@pmotley]

That little tank will drain pretty quick. BMW Boxer engine is basically a Radial with all but 2 cylinders removed.

[@vl639]

Now I know what I want for my next bike! That’s rad!!

[@OOICU812]

Radial engine motorcycles... an answer without a question.

[@ropeswingify]

Highlight.. The 'Bridgestone' pythons. What a build.

[@daniammarila5131]

[@stoufer2000]

Wow, that's impressive engineering. Looks great..

[@77gravity]

I wonder how much the gyroscopic effect affects the cornering, for a vertically mounted engine? Turning one way will tend to lift the nose, reducing front wheel grip, and turning the other way will push the nose down, increasing the steering effort. Also, the bike will resist leaning into the turn. For a horizontally mounted engine, the only effect will be that the bike resists leaning into the turn, with some change in front/rear balance going with that lean. But maybe the forces will be similar to a standard block engine. I dunno.

[@DaDaDo661]

That's a good point. I wonder if you can get the engine idling at a high enough speed that the bike wouldn't tip over even when standing gstill?

[@SoI_Badguy]

It's not like it's a giant flywheel. The crank isn't THAT heavy.

[@emansulaeman1761]

3:07 indonesia🇮🇩😊

[@wellardbr]

Not one danged air filter in those frigging carburetors! Outrageous.

[@mf59cmnz]

So are any of these guys going actually get on it and show how it runs rather than just above idle whats the point unless your going to use it. Thought about building but have yet to see what these motors are capable of. All my vmaxs from 85 to 2015 some turbo but curious of the torque on these motors so if anyone has some videos please share

[@blasthead1722]

i'd like too see a radial engine powered bike set up for drag racing.

[@thomaslemay8817]

Aircraft engines are designed to run at 2000 to 3000 rpm because propeller work best at that rpm. Aircraft engines make massive amounts of torque.

[@titozanella7704]

Indonesia is AWSOME

[@dekeprojeck5038]

Number 2 from purbalingga indonesia

[@donaldconsole9695]

The ignition wiring looks like a proper mustache

[@SkypowerwithKarl]

Sounds so much better than a Harley.

[@thepsychicpeach8425]

The idea of a radial engine in a bike seems so right.

[@stevenporter375]

The flat radial one would be hard to turn corners on with the engine acting like a giant flywheel, be hard to lean in to the corner I think.

[@redtedredted0012]

Only the crankshaft spins.

[@jaykrauss7613]

How does it not flood cylinders with oil? I know it's dry sump, but how? Lmk please 😁 thanks.

[@LonesomeNomad137]

I'm with Matt Bowen, I can feel those pipes burning my calf and probablymore

[@billrandell4641]

WOW..Fine Job!!..VERY COOL!!👍👍👍🇺🇸

[@beardo52]

If those are Rotec Engines, I wonder how many of them still run.

[@alternator7893]

@JAWA TINO did you see “Furiosa”?. Dementus bike has a radial engine and looks very similar to the bike at 6:05

[@Ktmfan450]

When I saw the bike in Furiosa I couldn't believe such a thing was real But it even sounds like the real life version

[@alexanderjoseph6984]

@@Ktmfan450 it is the bike from the movie, its called Lucky 7, well one of them used for the movie, Chris Hemsworth took home the one with a silver tank

HAVE YOU EVER BEEN AROUND ONE OF THESE.THE HEAT THAT COMES OFF THESE BIKES ,IS INTENSE, ONLY RIDE THEM IN THE WINTER TIME.THERE USELESS.

Chris Renek all uppercase makes you a moron, or, a Trump

[@OOICU812]

Yeah, and you might wanna think twice about wearing shorts riding one of those.

[@Lurod_]

OK DUDE

[@hipwave]

where is the sidecar tank to store all the fuel they guzzle ? :D

[@loopi222]

Imagine having to drain your lower cylinders of oil everyday

[@Sturmovik1946]

Ah but you see Ivan, if you put the engine on it's side all of the cylinders are on top! No more oil in the cylinder.

[@mcguire4162]

What kind of radial is used on the vertical mounts bikes?

[@ollies2240]

Richard Maguire Those a brand new Rotec radials made in Australia. -Ollie

[@briankimmell7960]

Any weird gyroscopic momentum? Giant flywheel effect? I love these types of bikes

[@darrenhawkins924]

Seems like it would be a stabilizer

[@draconian6692]

The exhaust is like right near where your thigh would be

[@savedbygrace2001]

They're cool but do they over heat?

[@thomasstrickland0]

Bob Janvrin I would imagine so if they weren't moving. They're air cooled after all.

[@savedbygrace2001]

That''s what I was thinking. Plus I believe they are designed to be turned into the oncoming wind to cool each cylinder

[@maibbomaibb8006]

[@JessHull]

At least the bikes could make use of rotecs, as they should never be anywhere near an airplane.

[@billbright1755]

A two row radial would give more power a be smoother. I hope he doesn’t ride that in a sandstorm. No air filter. Need a stereo playing “ the heat is on”

[@garyquail2347]

Why would think that a radial engine should Face Forward like that on an airplane instead of being transverse mounted for better Cooling when riding forward on the road so that all the cylinders can be equally cooled when operating on the road but seeing that these engines are mounted differently wouldn't at least two maybe three cylinders whould overheat to the extreme.?

[@isaacwhite7411]

I don't see how those plane engines keep from over heating cause there not built for that ,there's no air flow threw the cylender fins.

No Cooling. Killing those engines.

5 CARBS that was funny how they had to cover them up so it would start probably just cold start hope he has all his buddies with him when when it comes to 1st start up not a good idea to leave open like that get to much crap in the carbs unless just show bike but I'm sure a ggod ride I wouldn't leave them open
