Abstract
A motorcycle frame and suspension system employing a backbone frame member extending rearwardly over an engine and then downwardly where it is associated with an inverted U-shaped center frame. Two pivot mechanisms for a rear fork are positioned in line with the ends of the inverted U-shape center frame and a cushion member is located therebetween. The cushion member is linked at its first end with the middle of the center frame and at its second end to a linkage mechanism fixed to move with the upward pivotal motion of the rear fork. The mechanism is so proportioned as to provide an increasing rate of upward motion to the cushion member as the rear fork moves upwardly. The two pivot mechanisms are not identical, one allowing axial sliding movement and the other not allowing such movement.
