In an elastic suspension system provided with a shock absorber (6, 106) for the rear wheel (5) of a motorcycle, the shock absorber (6, 106) is pivotally connected by its lower end to a shock absorber-supporting bell crank (11) fulcrumed about the rear wheel fork (3). A guide arm is articulatedly connected by one end to the shock absorber-supporting bell crank (11), and by its other end to the motorcycle frame (1), at a point (15) higher than the pivot point (2) for the fork (3), and in such a manner as to obtain an articulated quadrilateral (2, 15, 13, 12) with no intersecting sides. This arrangement increases the excursion of the shock absorber (6, 106) and makes it possible to provide only one shock absorber (6, 106), arranged in the same vertical plane as the rear wheel (5). |
