Abstract
A suspension system for the front wheel of a motorcycle wherein a fork that carries the front wheel is connected to the frame in a manner that the steering axis of the fork in response to front wheel deflection by bumps is displaced parallel to itself relative to the frame. A specific example of such a suspension mechanism is a double A-arm connection. Handlebars are rotatably mounted to the frame. A connection between the handlebars and the fork is made in a manner so only rotation of the handlebars will cause rotation of the fork about its steering axis, and the connection does not affect suspension movement of the wheel relative to the frame. Examples of the steering connection are a folding bar and a hydraulic system.
