ABSTRACT:
A motorcycle has a frame assembly including a main frame supporting front and rear wheels on a central line thereof. A connecting member is mounted on the main frame between the front and rear wheels, and a subframe is mounted on the connecting member and is capable of banking laterally about the connecting member. At least one of the front and rear wheels is a drive wheel. At least the drive wheel is capable of preventing the main frame from banking laterally. Centrifugal forces generated upon cornering are counterbalanced by centripetal forces produced when only the subframe banks laterally. The drive wheel supported on the main frame which does not bank has an increased road gripping force. Thus, high-speed cornering is possible.
