The application discloses a compensating mechanism for vehicles having two or more wheels with one of those driven wheels being pivotally mounted at the rear end of a swingarm. The compensating mechanism is comprised of a eccentric cam arrangement for the forward end of the swingarm to pivot on and a rocker arm with connecting members to interconnect the swingarm and the eccentric cam. A method of controlling the rotation of the eccentric cam with respect to the swingarm is also disclosed to allow the rear driven wheel to remain a fixed distance away from the engine driver sprocket as the swingarm moves with respect to the driver sprocket.
