ABSTRACT:
A motorcycle having a cantilever-type rear swing arm pivotally mounted to the vehicle frame. A cushion member associated with the rear swing arm extends between the upper frame and linkage below the swing arm through an offset bore in the swing arm. A rear wheel is arranged on an axle supported at one end of the rear swing arm with a brake disc therebetween. The brake disc is aligned with the centerline of the vehicle as is the wheel rim. The hub of the wheel is arranged with a concavity to accommodate the brake disc. The swing arm is arranged such that it gradually increases in thickness as it extends rearwardly from the front pivot. The thickness is maximized near the center of the swing arm at locations which approach the mutual tangent lines of the pitch circles of drive and driven sprockets of a chain drive mechanism. Sliders are positioned to accommodate the chain when necessary.
