The utility model belongs to the technical field of the motorcycle, a motorcycle rear -mounted linkage is proposed. A motorcycle rear -mounted linkage who provides is including frame (5), back vent (1), rear damper (3), connecting rod (2) and connecting plate (4), connecting plate (4) platelike structure for having three hinge hole, the connecting plate is articulated with trailing axle (7) through I (the 4 -1) of hinge hole who is located on trailing axle (7) axle center, connecting plate (4) are connected with the one end of connecting rod (2) is articulated through II (4 -2) of hinge hole, the other end of connecting rod (2) articulates on frame (5), the upper end of rear damper (3) is connected with frame (5) is articulated, III (4 -3) of the lower extreme of rear damper (3) and the hinge hole of connecting plate are articulated, and III (4 -3) of hinge hole are located hinge hole I (4 -1's) lower part at initial position. The utility model provides a contradiction between rear -mounted linkage rigidity and the stroke, more soft among the driving motor vehicles, comfortable.
