Title: Power unit suspension system for motorcycles

Abstract: A power unit suspension system wherein a vehicle frame and a front lower portion of a power unit are connected with each other through a link rotatable about its front and rear pivots. An elastic body is provided between the link and the power unit. Rotational loads due to the power unit weight and rear cushion reaction acting on the link from the power unit side are elastically supported and converted into a moment of rotation.
