An improved motorcycle frame (20) has a first part (21) and a second part (23) mounted for pivotal movement relative to the first part about an axis (x-x). The improvement includes a cushioned bushing (17) operatively arranged between the two frame parts for enabling pivotal movement therebetween and for damping vibrations transmitted therebetween. The bushing has a rod (45) substantially coincident with the pivotal axis; a first cushion (27) provided with a blind recess for receiving one marginal end portion of the rod; a second cushion (27') provided with a blind recess for receiving another marginal end portion of the rod; and compression means (37) for exerting axial forces on the cushions to create forces between the cushions and the rod marginal end portions. In a preferred embodiment, the cushions are made of dual-durometer urethane materials.
