First Claim
1. A rear suspension for a motorcycle having a frame, comprisinga rear wheel support frame pivotally mounted to the frame of the motorcycle such that the frame and said rear wheel support frame exhibit relative pivotal motion with operation of the suspension;

Abstract
A suspension system for the rear wheel of a motorcycle employing a transversely mounted cushion member located below the rear wheel support frame of the suspension. Pantograph type linkage is employed to translate vertical relative motion of the rear wheel support frame into horizontal transverse motion actuating the cushion member. The linkage is pinned to both the motorcycle frame and to the rear wheel support frame as well as to the transversely mounted cushion mechanism to achieve the foregoing result. The cushion mechanism itself includes a hydraulic damper and a coil spring concentrically arranged.
