Abstract: A motorcycle suspension using an air bag in place of a spring, having a front bag bracket that is fixed to the motorcycle main frame and a pivoting rear bag bracket that is attached to a swing arm of a motorcycle. An air bag is sandwiched between the front bag bracket and the rear bag bracket and is compressed and extended with the action of the rear bag bracket and the swing arm. A shock absorber is mounted in its conventional place and dampens the motions of the swing arm and the rear bag bracket. The air bag is capable of being inflated or deflated by the driver either while driving or stationary. The front bag bracket and rear bag bracket are pivotably attached to the main frame of the motorcycle with a common pivot axis, allowing a scissor like motion, which allows the suspension to react in a conventional manner.
