Abstract: 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.

Abstract: Provided is a rear swinging fork (1) for a motorcycle, die-cast in one piece and featuring two longitudinal extending supporting arms (2, 3) each having three supporting walls (6, 7, 8), and a transverse cross member (4) connecting the supporting arms (2, 3). Each of the supporting arms (2, 3) has a mount for pivotal location of the rear swinging fork (1) on a motorcycle frame, and includes in the region of the ends of the supporting arms, opposite the mounts (5), a wheel mount (11) for the rear wheel of the motorcycle. The portion of the fork between the cross member (4) and the mounts (5) is openly configured, and the supporting arms (2, 3) feature in a section transverse to the longitudinal direction of the rear swinging fork (1) an upper supporting wall (6), a lower supporting wall (7), and an inboard supporting wall (8) connecting the upper (6) and lower supporting wall (7) and located in the longitudinal direction of the rear swinging fork (1), with a cavity (16) formed between the supporting walls.

Abstract: A motorcycle frame, and motorcycle with the frame as disclosed. There is disclosed a motorcycle frame having tubes extending away from a steering head tube in a three-dimensional trellis composite assembly of frame main tubes, interconnected by frame struts, paired upper and lower frame main tubes oriented, along at least a portion of their lengths, substantially parallel to each other. A single tube is oriented parallel to the lower frame main tubes, and arranged between the upper frame main tubes and the steering head tube.
