I'm thinking of building a motorcycle around a 12a. It would be mounted transversely (sideways?) and I'm planning on using a steel trellis frame (kind of like ducati) with modern sportbike geometry. I'm just wondering on how well a rotary would work on a motorcycle or if there is a(are) major problem(s) I have overlooked. Smaller rotaries have worked great (Norton f1 sport and Norton NRV588).

Also, how much does a 12a weigh?

I don't know... with at 12a, that might be kind of wide.

I'g go with a single rotor, and maybe turbo it... something exotic

Rodney Aguiar’s “Revelation” is a cross-species rebirth. The motor, a Mazda 13B rotary, came from a neighbor’s wrecked RX-7, while a parted-out BMW 1100GS provided the transmission, swingarm and rear wheel. A pranged Gixxer 750 contributed its front end.

They made rotary motorcycles, they didn't work to well. The motor was way too heavy and made the bike very unmanuverable. Say good by to laying the bike flat around turns and doing wheelies.

I see I need to explain my intent a little better. First of all, I'm not building a razor sharp repli-racer, what I had in mind was a standard, or a touring. I know using a 12a will be a little wide and heavy, but it won't be as excessive as a lot of production bikes. And the Norton NRV588 weighs 130kg dry(about 286lbs) which is about 100lbs lighter than most 600's. http://www.nortonracing.com/race/

The Norton rotary bikes are REALLY good bikes.

If you want to go with a 1-rotor, Atkins actually has a 1-rotor that they sell with a stand-alone and everything. All you need is a tranny to hook it up to.

Take a look, it only puts out 100hp at the flywheel (on stock ports), but the motor weighs almost nothing because its down a housing and rotor.

Bridgeport motorcycle?

Did anyone else notice in the picture that it says "What would Jesus ride?"

suzuki made a rotary bike in the late 70s early 80s i think.. i just remember i wanted one so bad.

That bike ended up costing Suzuki something like $700 for each unit sold... Great idea -poorly executed.

Yes Suzuki made the RE5- I have two not because they're great bikes but because they're rotary powered. Only a true enthusiast would understand....

I've seen a transverse mounted 13B race bike here in oz and it was quite cumbersome- the bike above with it mounted north-south with the beemer transmission looksl like a great idea.

Whichever way you go, good luck and good to see someone thinking outside the box!
