ABSTRACT:
A generally open, welded-up type of motorcycle frame wherein the pivot axis for the rear wheel suspension system is disposed forwardly of the rear end of the frame so as to provide a large degree of suspension travel with small angular movements and without necessitating a large wheel base. The construction also minimizes torsional bending and sheering forces on the frame members that support the rear wheel.
