A rear wheel suspension device for a motorcycle has a support frame comprising side bars extending from a horizontal bearing cylinder and having a cross member fixed to the side bars to define an opening. An upright damper is pivoted to the main frame and extends through the opening and is pivotally connected to short arms of bell crank members. Long arms of the bell crank members are pivoted to the support frame. Tension rods are pivotally connected to the main frame and to the bell cranks. The long arms each comprise parallel spaced side plates, for weight reduction, and the rear wheel drive chain extends through one of the long arms between said side plates. |
