ABSTRACT:
A single track vehicle includes at least one front drive wheel and one rear steered wheel. A steering mechanism causes the front and rear wheels to substantially track each other during a turn and also causes the center of gravity of the vehicle to be raised during a turn. The steering mechanism further allows simultaneous variance of both the camber angle and turn angle of the rear wheel for even more exact tracking of the front and rear wheels. The steering mechanism further provides for a more linear relationship between the rate of change in the angle of rotation of the steering head of the vehicle and the rate in change of the turn radius of the vehicle. In other aspects, a steering mechanism is provided which allows the operator to maintain a constant width between his hands while turning a vehicle incorporating the steering mechanism. Preferred embodiments of the vehicle are shown in the form of a bicycle and a motorcycle.
