Abstract
An improved engine supporting structure for a motorcycle wherein a power unit is constructed integrally of an engine, a crankcase and a transmission case and is subjected to pivotal motions with respect to the frame together with a rear wheel. The engine is so arranged that its main axis of inertia is substanially horizontal, and the engine constituting a part of the power unit is pivotally connected to the lower end of a link which in turn has its upper end pivotally connected to the frame. The link is so arranged that its upper and lower pivots are substantially in a vertical line, and the rear portion of the power unit supporting the rear wheel is connected to the frame through a shock absorber. In this manner, the transmission of engine vibrations to the frame is restricted, the following characteristics of the rear wheel in the longitudinal direction are improved, and the riding quality is improved.
