A motorcycle frame has an improved front and rear suspension system incorporating two horizontally placed air bag suspension mechanisms, the motorcycle frame comprising an upper support member having a front backbone tube attached to two rear backbone tubes, a lower support member having a descending front downtube attached to two lower frame rails, an upper support brace attached between the front backbone tube and the descending front downtube, a head tube steering member pivotally attached to the descending front downtube, two rear upright frame members attached between each rear backbone tube and each lower frame rail and a rear axle frame member pivotally attached between the two rear upright frame members to the two lower frame rails. A first air bag suspension mechanism is installed between a front portion of the front backbone tube and the head tube steering member in a horizontal plane to absorb and dampen the vibrations and shock to the front wheel of a motorcycle, while a second air bag suspension mechanism is installed between a rear portion of the front backbone tube and the rear axle frame member.
