ABSTRACT:
A suspension system for the front wheel of a motorcycle. A pair of upper and lower control arms extend forwardly from the body of the motorcycle and are attached by universally pivotable ball joints to a kingpin which extends along one side of the front wheel. The front wheel includes an offset hub and is journalled in a cantilevered arrangement to a bearing assembly which is affixed to the lower end of the kingpin and which is positioned at the center of the wheel. The control arms are hinged to the body and are appropriately sprung and damped so that the kingpin and front wheel swing vertically in suspension travel with respect to the body in response to weight and shock loads on the front wheel. The kingpin is connected to a handlebar assembly by means of a telescopic splined steering column. A variety of springing and damping mechanisms may be adapted to the suspension system. The system minimizes the tendency of the motorcycle to dive during hard braking of the front wheel, and also results in weight and shock loads being transmitted directly to points on the body which are low and close to the center of gravity of the motorcycle.
