A clutch spring kit that is particularly suited to replacing a standard motorcycle pressure plate in a diaphragm spring biased clutch assembly. The clutch assembly is activated by centrifugal force acting on spherical deflection elements. A plurality of pocket elements are generally arranged in an annular array formed in the spring side of a clutch pressure plate. The pocket elements are generally disposed radially inwardly of and adjacent to an upstanding lip element on the first side of the pressure plate. The pocket elements include ramps that extend within the pocket elements generally outwardly toward the lip element and angularly upwardly towards the spring side. A spherical deflection element, such as a ball bearing, is received in each of the pocket elements for generally radial movement along the ramp. A diaphragm spring, the periphery of which is confined by the lip element, is in spring biasing association with the first side of the pressure plate. The spherical deflection elements engage the diaphragm spring and deflect its periphery axially outwardly as the spherical deflection elements move axially upwardly and radially outwardly along the ramps under the urging of centrifugal force.
