  • Patent number: 4542910
    Abstract: Two embodiments of motorcycle suspension systems that are particularly adapted for use with the steered front wheel. Each embodiment achieves a non-linear suspension rate through the use of a linkage system for loading the suspension element upon relative movement between the wheel and the frame. Each embodiment reduces unsprung weight by loading the suspension element from an intermediate portion of a link that is pivoted to a sprung portion of the motorcycle. In one embodiment of the invention, the linkage system is disposed so as to minimize bending forces on the wheel supporting element that would otherwise be encountered due to the castor angle.
