You can't really compare your motorcycle to your car engine. You didn't state what kind it is but most bikes are 2 cycle which don't have valvetrains at all so there is no limiting factor there. The other factor is number of cylinders. A 1 cylinder bike engine isn't gonna have the reciprocating mass of a multi cylinder car engine.

Every sportbike I have owned revved above 13,000rpm, was a 4 cycle, 4 cylinder engine, with OHC.

My '98 Honda CBR600F3 has 600cc and runs the 1/4 in 10.93sec. stock.

The 4 cycle sportbike motorcycle engine is the same as any 4 cycle car enigne internally and fundamentally. The main differnce being a much smaller bore and stroke, less mass, higher revs, and very little torque.

You are thinking of 2 cycle dirtbike motors.

Ok are talking about the overall size of the engine is larger or are talking about displacement. because i see ohv engine in larger v-8's some older v-6. and your right the heads are larger on the dohc because of all the cam sprockets.

hey who said honda has a werid 3 valve hey my girl has a sl55 that has 3 valves so ha jk.

and i think hte guy knows along with alot of us that if he says he has a motorcycle  with dohc we all probably figure its like a small stroke high reving inline 4 just forget about 2 cycle's no torque for

Speak english much?

I was thinking the same thing.
