Now, everyone knows that motorcycle engines work at much higher rpms than car engines.
They also produce lesser torque than a car, because (and correct if I'm wrong) bikes don't have as much load on them as cars do.
Can anybody tell me what goes in an engine that decides that when power is being generated in the cylinder, torque increases more than rpm in case of a car engine, whereas in a bike engine torque remains much lower while rpms rise to very high values?
I'll try to frame this a little better. Power (in kW) = 2(pi)(N)(T) / 60000. N = rpm, T = torque in N-m. Bike engines go upto 14000 rpm. Car engines go upto 8000-9000 rpm. Car engines produce way more torque, while bikes produce lesser torque. How does the engine produce less torque and more rpm in one case and more torque and less rpm in another case?
Is it a mechanical design consideration? Is it something elementary that I'm thinking wrong?
