US Patent 11485446 Single-sided swing arm for a motorcycle

A single-sided swing arm for a motorcycle having a traction means for driving a rear wheel of the motorcycle, the swing arm having a first section for rotatably supporting the rear wheel and second sections for pivotally attaching the swing arm to a structural member of the motorcycle. Geometrical centers of the first section and of the second sections define a virtual swing arm center plane, and a rocker arm with an upper side is between the first and the second sections. The rocker arm has a first side wall region and a second side wall region substantially opposite thereto, and the second side wall region extends into the region of a second section; the two side wall regions are connected to one another by a stiffening girder designed for the passage of the traction means. The stiffening girder extends into a region below the swing arm center plane.
