A suspension system for a motorcycle including a motorcycle main frame, a wing arm pivotally mounted to the motorcycle main frame about a pivot axis, and an air-bag suspension unit. The air-bag suspension unit includes at least one air bag constructed of an elastomeric material. The air pressure in the airbags in adjustable on the move by the use of pressure regulator operably connected to a small compressor mounted on the motorcycle. The air bag is housed within a slidable housing and is mounted at one end to the slidable housing and at its other end to mounting brackets on the motorcycle main frame. The housing is attached at its front end to the motorcycle main frame and at its back end to the swing arm. The housing also includes slide rods fixed to its forward end which slide within a pair of bushings. An alternate embodiment incorporates a conventional shock absorber along with the air bogs to improve the handling of the motorcycle on rough or uneven terrain.
