  • Motorcycle provided with a steering hub
    Patent number: 6349784
    Abstract: The invention provides a motorcycle with hub steering, the axle of the hub being fixedly connected to first support arms and being disposed in such a manner that it can turn with respect to the hub body. Second support arms are arranged in such a manner that the front pivot points and rear pivot points lie on non-parallel lines. Attaching the front wheel in this way results in an improved suspension and increased stability of a motorcycle with hub steering.
