Abstract
Steering arrangements for motorcycles wherein the rear wheel is supported for steering movement and is mechanically coupled to the mechanism for steering the front wheel so that both wheels will be steered in unison. An arrangement is provided to adjust the steering ratio between the front and rear wheels to suit riding conditions and rider preference and a caster angle is chosen to minimize effective wheelbase changes under suspension travel.
