Abstract
A strut for a front fork of a two-wheeled vehicle including an inner tube, an outer tube and a cushion spring resisting the telescoping of one tube toward the other. A damping mechanism is illustrated also using damping fluid. Bearings are provided between the inner and outer tubes which include a collar slidably mounted to one of the tubes. A circular bearing is positioned adjacent the collar to retain the collar relative to the other tubes. The collar may move with the tube on which it is mounted through a preselected distance at which time it is constrained by the other tube. A spring biases the collar away from the stop provided on the other tubes such that some relative motion between the tubes can occur prior to the sliding of the collar along the tube upon which it is mounted.
