ABSTRACT:
A compensator assembly for a motorcycle engine including a hub and a compensator coupled to the engine crankshaft. The compensator is axially moveable along the crankshaft axis and a sprocket is supported for rotation with respect to the crankshaft. Cam surfaces on the compensator and the sprocket cooperate to transfer engine torque from the crankshaft to the sprocket. A spring biases the compensator into engagement with the sprocket and a resilient member is positioned between the hub and the compensator to resiliently limit axial movement of the compensator toward the hub. Torque pulses from the engine are damped by allowing relative rotation between the sprocket and the crankshaft.
