Lightbulb Wankel Motorcycle?

This is a really bizarre topic, and probably 99% hypothetical, but my friend is looking into buying a motorcycle and somehow we got the idea of buying a scrapped RX-7 and a used bike big enough to hold a 1300cc engine, and stuffing the RX-7 engine into it. Is this even possible? I'm interested to hear what you guys think of this idea.

Haha, I wonder if you could just crank on the power, hold on tight and do a backflip. Talk about ludicrous speed! You might even go to plaid!

Norton f1 had a rotary. It was a pretty good looking sportbike also.

And no I don't think your idea will work. Think of how hard it will be to mount it! Where are you going to put mounts on engine? How are you going to cool the thing? That's a lot of heat, muchless between your legs. And what about a moto trans that will mate without serious modifications? Plus, a rotary engine is small and light, but only in terms of cars. That would make a freaking heavy bike!

That's a specially designed V6. They didn't pull one out of a mustang and put it in a bike.

Might be cheeper to find one of the old bikes in the above thread and update the motor?
You could also see if you can get a frame from http://www.v8bikes.com/ and fab a way to mount a Renesis

They make motorcycles with Chevy 350cid engines.

A 13B RE would be a lot lighter than a V8. I think one of their bikes has a 502cid

I think the only thing with having a rotary motorcycle is being able to say "I have a rotary powered motorycycle!"

You would have a much faster and more powerful motorcycle if you just bought a gixxer 1000 and modded. Heck you wouldn't even have to mod it really. If you wanted to go really big you go Turbo or NOS.

Someone built a motorcycle using a Ford flathead V8 so you should be able to do it.

The whole point of it IS to say you have a rotary powered motorcycle. It's not about making a faster better bike than what is out there.

I think it would be cool. You'd need more space for cooling than for the motor though.

I have seen one of these in the flesh when I used to race GP250 motorcycles here in Christchurch NZ... maybe 5 or 6 years ago.

From memory it was an *** to start (they used another motor to crank the rear wheel over in a high gear) but when it did fire up its a sound I have never forgotten.....mean as

It wasnt blindingly quick, but it was sooo freakin cool (and this was before I owned a rotor myself)

That's the one, the Suzuki RE-5 Rotary was sold here around 1975, for a few years, single rotor 497cc (similar to a 10A R100/RX-3 cut in two), not a sales success, don't recall its reliability, come to think of it, excess heat from an inefficient cooling system was an issue, like anyone who want to do any type of Rotary Transplant......keeping coolant temps LOW!

It was a very fast 2 wheeler.

Did you guys have them in the US, Obviously not

About 3 month ago I passed a Suzuki RE-5 on I-95 near Boston. (So I guess that means that they must have them in the US.)

I would have really like to see that. I guess that would be a pain to have to start. I've seen a couple for sale...I was just curious , and I found one for sale in England for $18,000 US!

That would be "cool" if a company made another rotary moto but I think heat would be a hard problem to solve.
