  • Patent number: 8448970
    Abstract: A suspension system for a steerable front wheel of a vehicle such as a motorcycle has two substantially identical, straight, elongate, tubular members that extend forwardly and downwardly from the vicinity of a handlebar of the vehicle along opposite sides of a lower rear quadrant of the front wheel and have open front end regions that at least partially enclose compressible coil suspension system springs. Elongate arms are pivotally connected to brackets that are rigidly secured either above or below the open front end regions of the elongate members, define surfaces that extend across the open front ends of the front end regions to be pressed against by the suspension system springs, and have upper end regions that support opposite ends of a front wheel's axle that extends between the two elongate arms. By adjusting the extent to which the suspension springs are compressed, the ride provided by the suspension system is adjusted.
