The present invention is generally directed to a swing arm configuration and, more specifically, a swing arm that is supported by a shaft of a motor, such as an electric motor of a motorcycle. The configuration includes a swing arm assembly that is supported by a shaft of a motor at one end and a rear axle at the other end. Advantageously, the shaft of the motor may be a structural component of an electric motorcycle and serve as the swing arm pivot as well as the drive shaft.

A straddle vehicle comprises an axle; an external member which is externally fittable to the axle; and a fastening member fastened to the axle to prevent disengagement of the external member. The axle includes an outer tube member to which the external member is externally fittable, and an inner shaft member which is inserted into the outer tube member and is longer in an axial direction of the axle than the outer tube member. The inner shaft member includes a shaft part which is internally fittable to the outer tube member, a male thread part formed in an outer peripheral surface of a first end portion of the shaft part, and a retaining part protruding radially outward from a second end portion of the shaft part, the retaining part being configured to retain an axial tension of the inner shaft member generated by fastening the fastening member to the axle.
