Abstract
A front wheel suspension assembly for a motorcycle includes parallel telescoping forks of the hydraulic shock absorber type which straddle the wheel and which are inclined in a forward direction. The bending moment imposed on the telescoping parts by this inclination is partly or fully opposed by a counter bending moment imposed by one or more springs positioned rearward of a vertical plane containing the wheel axis and below a bottom bridge joining the front fork tubes. The purpose is to reduce the frictional resistance between telescoping forks in their axial sliding motion. The springs apply the compensating bending moment between the telescoping parts.
