A brake band and drum assembly holds the energy in the spring until the brake is released by the rider, whereupon the spring unwinds to drive a sprocket wheel mounted on the common hub, which sprocket wheel is connected to a sprocket wheel mounted on the spindle, turning the rear wheel drive sprocket wheel and the rear wheel.

Abstract: A motorbike stabilizing device consisting of outriggers extending on both sides of the bike and connected pivotally and independently to the frame of the bike. A wheel is mounted near the tips of both structures which runs along the ground. An actuating lever located on the handlebars allows the rider to control the lean angle of the bike as it goes through a corner at various speeds and corner radii. The lever actuates a pneumatic cylinder which is connected to both structures keeping them firmly planted on the ground and allows the lean angle of the bike to be selected.The invention assists the rider to overcome the natural fear of steep lean angles, the fear of quick or sudden turns and the fear of losing traction. The rider learns to lean his body with the bike in a turn, thus lowering the center of gravity of the bike/rider combination which creates the most stable conditions.

Abstract: A center parking stand for a motorcycle which balances the motorcycle without substantially bearing the weight of the motorcycle. The stand includes a mounting portion which mounts the stand to the motorcycle and allows the stand to rotate between stowed and use positions.

Abstract: The present invention is related to a power driven support mechanism for parked two-wheeled motor vehicles, in which the support member pivots between its upright and retracted position by activation of a support member drive mechanism. In particular, it concerns a support mechanism and its installation configuration, constructed in such a way as to eliminate the above described problems of exposure to the elements, diminished ground clearance, and excessive lateral bulk. By constructing the vehicle in such a manner that the under-chassis support material is caused to extend beyond the chassis in an interior and posterior direction, and furthermore, so that the anterior aspect of the power unit for applying driving force to the drive wheel (conventionally the rear wheel) is mounted on this protruding under-chassis support material, a space is created between the protruding under-chassis support material, the power unit, and the under-chassis.

Abstract: The present invention solves the problems of the electrical surge and reduced reliability related to the shock loading experienced by previous two wheeled vehicle stands when the stand member contacts the ground during the time it is being driven by the stand motor to a position for supporting the two wheeled vehicle. This is achieved by having a drive mechanism consisting of a plurality of reduction gears to transmit the drive from the stand motor to the stand member, thereby reducing the torque loading on the stand motor, and by mounting the drive mechanism so that it can move relative to the body of the two wheeled vehicle when the stand member first contacts the ground, and restricting this movement with a buffer device which absorbs the shock loading.
