Abstract: A plurality of clutch levers transmit force to a pressure plate of a clutch. The lever ratio of the clutch lever is variable as the clutch lever moves from an engaged to a disengaged state. When the clutch is engaged, the clutch lever presses the pressure plate to engage clutch discs. The lever ratio of the clutch lever is relatively large, allowing for an acceptable clamp load. When the clutch is disengaged, the clutch lever lifts from the pressure plate, disengaging the pressure plate from the clutch discs. When the clutch is disengaged, the lever ratio is relatively small, allowing for more clearance between the pressure plate and the flywheel and an increase in pressure plate lift. By using a clutch lever having a variable lever ratio, both clamp load and clutch lift can be maximized. The conditions exist during the entire lift of the clutch.
