Abstract
A motorcycle frame and trailing arm construction for providing a extremely high strength, light weight assembly. The frame is comprised of a head pipe and a pair of downwardly and rearwardly extending main frame members the center of which substantially intersect a pivot axis for a trailing arm that supports the motorcycle rear wheel. The trailing arm has a triangular configuration in side elevation and the rear suspension element is loaded by the thickest portion of the trailing arm so as to provide high strength. A bearing arrangement is incorporated for the trailing arm that permits removal of the driving sprocket that is concealed behind the trailing arm for servicing.
