ABSTRACT:
A front wheel suspension system for a motorcycle including a telescopic hydraulic shock absorber mechanism which provides an anti-dive function upon braking of a front wheel of the motorcycle. In addition to a main oil passage which is intercepted upon braking of the front wheel, a bypass oil passage is provided between inner and outer tubular members comprising a fork pipe and a bottom case, respectively, disposed in a telescopically fitted relationship with each other. An adjustable orifice mechanism is provided in an intermediate position in the bypass oil passage. The suspension system provides an appropriate adjustment of the damping effect of the shock absorber mechanism in a direction of contraction of a front fork upon an anti-dive operation.
