ABSTRACT:
A suspension in a motorcycle or similar vehicle having a frame relative to which a rear fork with a rear wheel is moveable. The suspension is characterized by an elongated composite spring mounted at the front end on the lower front part of the frame and loaded at the rear end by one end of a link member the other end of which is mounted on the rear fork. The frame is provided on its underside with at least one deflecting member which is arranged in such a manner that it bears against the composite spring upon a relative low loading of the rear fork relative to the frame to change the spring rate.
