A motorcycle clutch utilizes a reduced clutch spring load with a corresponding reduction in lever effort by an operator to disengage the clutch. At higher speeds, and hence engine torque, the clutch clamp load increases by means of a centrifugal mechanism, supplementing the clamp load provided by the clutch springs, until a predetermined speed level is reached, at which point the centrifugal load is limited, and remains almost constant at all engine speed levels above the predetermined level.
