ABSTRACT:
A rigid motorcycle frame comprises a pair of spaced swingarms attached to a shock absorber which comprises a shock absorber casing or housing pivotally mounted on the swingarms and having a shock absorber rod which is pivotally attached to the motorcycle frame at a point below the housing whereby the movement of the rear wheel of the motorcycle causes the outer housing of the shock absorber to move upwardly relative to the shock absorber, rod which is attached to the motorcycle frame and which is opposite from the normal operation of a shock absorber. The shock absorber may include a spring means and/or hydraulic means to provide the usual resistance provided by a cushioning arrangement. In operation swing arms are moving downwardly the shock absorber moves its mounting points closer together which is different from most shock absorbers which move their mounting points further apart.
