Explanation:
The caster angle or castor angle is the angular displacement of the steering axis from the vertical axis of a steered wheel in a car, motorcycle, bicycle, other vehicle or a vessel, measured in the longitudinal direction. It is the angle between the pivot line and vertical.
An example of a chopper with a raked fork at an extreme caster angle.
The pivot points of the steering are angled such that a line drawn through them intersects the road surface slightly ahead of the center of the contact patch of the tire on the pavement by a distance called trail. The purpose of this is to provide a degree of self-centering for the steering — the wheel casters around in order to trail behind the axis of steering. This makes a vehicle easier to control and improves its directional stability
