Abstract: A vehicle including a frame, left and right wheels, and a leaning suspension system. The frame defines a longitudinal vehicle axis. The leaning suspension system includes a transverse beam, left and right damping members, left and right control arms, and at least one lean actuator. The transverse beam is coupled to the frame and pivotable about the vehicle axis. The left and right damping members are pivotally coupled to the left and right sides of the transverse beam. The left control arm is pivotally coupled to the left wheel and to the frame, and the right control arm is pivotally coupled to the right wheel and to the frame. The lean actuator is pivotally connected between the frame and the transverse beam. The lean actuator is configured to extend and retract to tilt the left and right wheels and to lean the vehicle while cornering.

Abstract: A vehicle comprising a frame, at least one wheel operable to contact a substantially horizontal support surface, a prime mover supported by the frame and in driving engagement with the at least one wheel, a suspension system operable to maintain the frame in an upright position while driving along a straight path and to permit the frame to lean relative to the support surface while cornering, and at least two headlights coupled to the suspension system and arranged in a substantially horizontal configuration, wherein the headlights remain in the substantially horizontal configuration when the frame is in the upright position and when the frame is leaning.

Abstract: An auxiliary lean control system is provided for controlling a lean angle of at least a portion of a vehicle. The auxiliary lean control system includes an energy storage device for storing energy to actuate the lean control system, a stabilizing mechanism coupled to the energy storage device and to the at least a portion of the vehicle for applying energy received from the energy storage device to the at least a portion of the vehicle to adjust the lean angle of the at least a portion of a vehicle, and a linkage coupled to the energy storage device and to the stabilizing mechanism for transferring energy from the energy storage device to the stabilizing mechanism. The auxiliary lean control system controls the lean angle of the portion of the vehicle in an absence of control of the lean angle by a primary lean control system.
