ABSTRACT:
A front swing arm suspension system for a motorcycle is disclosed. The system includes a single one-sided swing arm that extends around one side of the front wheel. The swing arm and an upper control arm are each connected to an upright, to which the wheel is journalled by means of a cantilevered live axle. The upright is oriented generally along the rake angle of the front wheel and extends from the wheel axle upwardly and around the front wheel to a telescopic steering tube. The lower portion of the upright is positioned inside the wheel rim so as to enable a brake disk to be splined to the live axle on the opposite side of the upright from the wheel. The swing arm and the control arm are connected to the upright by universally pivotable joints which accommodate swinging motion of the front wheel during suspension travel while also accommodating steering rotation of the wheel.
