Abstract
Two embodiments of steering arrangements for motorcycles wherein the rear wheel is supported for steering movement and is mechanically coupled by a positive linkage system to the mechanism for steering the front wheels so that both wheels will be steered in unison. In one embodiment of the invention, the positive linkage system includes irreversible gearing so that forces applied to the rear wheel will not effect its steering or steering of the front wheel.
