is this for real. cause if it is that would be sweet. i like old school bobers(is that the right word) and cafe racers. it be happy with a 1 rotor bike . if you can figure out a way to hook up a tranny ect ect let me know

You can do a 2 rotor like the one guy at sevenstock. Transmission you just need an adapter to adapt one off another bike.

It could be done.

i have a trans from bsa. the bsa motor was blown with pistons knocked out via head. i would mount motor one side, trans and maybe wide belt to wheel on the other to try to counterbalance the weight. maybe i would p-port the rotor housing for dirrrect injectio (and i have 2 mikunis from bsa motor).

this idea was a result of boring evening, and i am i the middle of widebody restoration so it has to wait. i also have not research it at all, but i lost a tear in my eye when i came w/ this idea in the first- got me exited. dj55d thanx for direction where to research

warwick...yeah this is the original southern red neck chopper- i love it

can some one post pics of how you would do the tranny. just confused as how a car motor will hook up to a bike trans. me my buddy where joking around about cutting the front half of a bug off and welding a bike swing arm on it.(i know it would be way more work) think of the t-rex

but rat rod style.

i dont know how tomount motor to trans yet. probably upon modifying the shaft i would create the same shaft end setup as bsa trans, allowing clerance for transition plate. the bsa tans has not been seperated from the motor yet but the idea is growing on me.

ok.here is another 1- butchered rx7 body on vw long travel frame set up,

Joker1337

Do you have a specific bike trans in mind?

drifted

yes. i bought this frame together with "bsa"-triumph similar engine and trans. trying to recycle the most i was thinking to use that trans. i have not seperated these 2 yet -some bolts are seized. origially i was going to replace w. same bsa or triumph motor, but used they cost at least 600 for dissasembled-ebay, to 1200 runing from the shop.....so why not frankenstein it?

triumph you need to be carful with with the bolts. i dont know what year yours is but they can be messed up. most that where meant for the states have us size bolts but not all. the ones meant for england ect had metric and that weird size that they dont use(starts with a w) my buddy had a bike shiped to usa from the person who bought the bike new. it had us spec bolts(sae is that right) metric and the odd ball size bolts all stock. so if you dont have a wrench that fits perfect its that odd ball size.


just my 2 cents. if you can figure out how to mount a trans and how to mount the motor i will send you my frist born.

Pickup the Jan 08' issue of Cycle World for some inspiration.Its the issue with the (drool) Ducati D16RR Moto GP streetlegal replica bike in red and white,on the cover.

Rodney Aguiar built what looks like a power cruiser, using a BMW tranny and swingarm mated to an FC 13B with sidedraft Webers making about 250hp.Its pretty cool looking but is horrendously loud,the cooling system is a nightmare and it only goes 18 miles on the 3 gallons of gas it can hold! He calls it a Bonneville runner.

If you are using the rotor engine, why not the rotory transmission as well? I had an old Yamaha Seca 650 that was shaft driven.

i would lover to make a trike with a Bonneville triumph frame. that would make it easy would just need to get a custome rear end made,hard mount it. id put the gass can between the rear wheels.

interesting. it says it has a bmw rear and trans. looks like many hours and $ went into fabrication of this bike. your feet must get hot

Rotary bike? Crazy but cool idea-

Was going top do this years ago for a guy who was dying to do it. Unlimited budget I just never felt like tying up more of my time in such a project.

warwickben- Your thinking of "Whitworth" for the strange hardware.

Can you imagine how loud that finished one is? I would love to run up next to a Hardley rider and show him what a loud bike really sounds like.

warwickben- Your thinking of "Whitworth" for the strange hardware. confused by what you mean.

i just dont under stand how you can have the motor hooked up to a normal bike tranny.

jgrewe

The odd ball size nuts and bolts you were talking about are Whitworth thread. It is actually a superior thread design than SAE. The threads are cut with rounded valleys instead of just a "V", it makes them stronger since ther isn't a stress riser at the bottom of the thread.

As for connecting the engine to a tranny, all I know is the Harley design has a seperate tranny and the hotrod guys run them with a wide gilmore belt to the engine. You could also use the tranny from a Honda Goldwing, they have flat opposed engines like an aircooled VW and the BMW motorcycles.

Look at it like this:

Any engine will only spin basically in one direction and the out put is at one shaft. The shaft might be bigger/smaller, but point being its still a round piece. From there you can attach a super small flywheel like a one off a bike. You just make the hole on the flywheel be able to fit on the rotary shaft. Then you have to custom build a case to hold the transmission, and clutch assembly in the center of flywheel position. This is the trickier part. Its a bit tricky but not doable.
