Holy hell, 200hp from a 700cc motor is insane.

and no traction control and 300lbs package rolling.

Disaster waiting for the right buyer.

This should be a MotoGP bike

[ChrisK]

I believe MotoGP bikes are over 235 hp aren't they? Still a ways to go there.

200hp in a 700cc engine = 285hp per liter. Increase displacement and you are there

true! definitely has a lot of potential.

The site the OP linked to says that the bike uses a "Rotron" twin motor to make that 200 hp. Here is Rotron's website:

According to their product line they don't have any motors that make 200 hp or even 100 hp, so it leads you to believe that they special made the motors for the motorcycle application. Maybe they'll special make a larger one to compete in the Moto GP world as you've suggested, who knows!

Part of the deal there is "rated HP" in an aviation use is under different requirements.  They've also got a pretty conservative compression ratio on the high output 600.

Rotaries also like playing with port timing more than is useful in an aviation setting.

I think they would have to go smaller to compete in Moto GP as rotaries are 2 stroke.  So that would be a 500 cc limit if allowed at all.  Very cool bike though, I always liked the rotary Nortans & old Suzukies.

Nope, they are four stroke.  They just sound mean.

Each face of the rotor counts as if it were a cylinder.  Intake, compression, power, exhaust. 

[caperix]

Ok, I had always figured that as they fire once per rotation they would be clasified more as a 2 stroke.

Assuming a Wankel triangle rotor, "rotation" counts from the eccentric (equivalent to the crank).  They actually fire three times per rotor rotation.  A two rotor is the equivalent to a v-6 of the same displacement.

The one in the OP sounds like a peripheral port, which will only ever be street legal on a production bike if they do the "limited homologation" that exempts it from noise and emissions laws.
