Two-wheeled motor vehicle

摘要

A two-wheeled motor vehicle (1) that includes a body frame (2). A rear wheel (9) is swingable through an area relative to the body frame (2) and a brake disk (52) is attached thereto. An exhaust muffler (39) is at a side of the rear wheel (9) and attached to a side of the body frame (2). A service caliper (53) is on the brake disc (52) for producing a braking force in time of traveling. A mechanical caliper (54) for quiescence prevents rotation of the brake disc (52)and is disposed on the brake disc (52). In a side view and in every position within the entire area through which the rear wheel (9) is swingable, the mechanical caliper (54) and the service caliper (53) are located below different sites of the exhaust muffler (39) that are each closest to the rear wheel (9) than any other site of the exhaust muffler (39) in respective cross sections taken in different axial positions of the exhaust muffler (39).
