Motorcycle.

摘要

A motorcycle has a frame assembly including a main frame (5) supporting front (1) and rear (3) wheels on a central line (C0) thereof, a connecting means (6) mounted on the main frame (5) between the front (1) and rear (3) wheels, and a subframe (7) mounted on the connecting means (6) and being capable of banking laterally about the connecting means (6). At least one of the front (1) and rear (3) wheels is a drive wheel, at least the drive wheel (3) being capable of preventing the main frame (5) from banking laterally. Centrifugal forces generated upon cornering are counterbalanced by centripetal forces produced when only the subframe (7) banks laterally, and the drive wheel (3) supported on the main frame (5) which does not bank has an increased road gripping force. Thus, high-speed cornering is made possbile.
