SMG or no?

Do you need less clamping force at 12,000 rpm pushing 200+ hp than a car?

I really dont know the answer, so yes that is a question.

torque, not weight is the key. and how much weight that torque has to move (which would be the "reverse torque" for lack of a better word, that the clutch has to channel through it from the engine to the drivetrain). A 400 pound bike with next to no torque isnt going to need much clamping force on the clutch.

Harley sturggled with that for a long time... somebody came up with a unique mechanism that mounted on the clutch to lighten up the pull a while ago. I'll see if I can't dig it up.

*edit* I can't find it.. but whatever it was I remember that you suffered a parasitic loss by using it.
