Abstract
Abstract A motorcycle in which the rider is comfortably seated in an adjustable support for his torso and feet, and in which the envelope of the motorcycle can be kept to a minimum so the rider can ride in an optimally comfortable position. A footrest and a seat are provided so the feet of the rider are axially forward of the rider's knees, as viewed in plan, and either the footrest or seat or both is adjustably movable so the axial distance between them can adjustably be varied. An engine on the frame can be mounted with its crankcase beneath the seat, and with its cylinders extending forwardly at an angle above the horizontal no greater than about 45°, beneath the thighs of the rider.
