    One of the less desirable byproducts of increased power is the need for a clutch spring upgrade, and the additional lever effort it requires. By adding the Variable Pressure Clutch (VPC) devise, clutch plate holding pressure is reduced at lower RPM’s, and increased as RPM rises, reducing the chance of clutch slippage as power builds. the VPC system reduces initial pressure and uses weights and centrifugal force to increase pressure as RPM builds. Clutch lever effort is reduced up to 50% at idle and low RPM, resulting in less hand fatigue, smoother engagement and easy neutral location.
