Motorcycle

摘要

A motorcycle has a frame assembly supporting a power unit, which is disposed between front and rear wheels, for driving the rear wheel. The frame assembly comprises a front frame supporting the front wheel and a rear frame supporting the rear drive wheel. The front frame is coupled to the rear frame and is swingable with respect to the rear frame laterally of the frame assembly. The rear wheel has a substantially flat tire for suppressing banking movement of the rear frame. The front wheel has a round tire for allowing banking movement of the front frame. The motorcycle also includes a rider's seat mounted on the front frame. A damping device is disposed between the front frame and the rear frame for damping banking movement of the front frame.
