The vehicle can be kept upright while traversing a slope.

Abstract: A rear wheel suspension for a motorcycle wherein the rear wheel is mounted to the frame by a swing arm assembly including at least two swing arms. One of the swing arms being pivotally connected to the frame at one end and pivotally connected to the other arm at the other end. The other arm having the rear wheel rotatably mounted thereto. The arrangement permits freedom of movement in any direction of the rear wheel relative to the frame with the plane defined by the rotation of the wheel.
