Two-wheeled motor vehicle

Abstract

The invention provides a two-wheeled motor vehicle having a main stand capable of suppressing enlargement of a rear portion of a vehicle body and achieving a vehicle body with a low center of gravity. The two-wheeled motor vehicle includes a rear arm (6) arranged to extend in a fore-and-aft direction at the rear of an engine (21); a main stand (26) having paired support legs (27) and (28) that extend in the fore-and-aft direction below the rear arm (6) and are spaced away from each other in the vehicle width direction; and a muffler (24) for expanding exhaust gas flowing from an exhaust pipe (23) in its inside. A rear portion (24e) of the muffler (24) is positioned below the rear arm (6) as well as between a rear wheel (8) and pivot support plates (4) and (5). Moreover, the rear portion (24e) is positioned between the paired support legs (27) and (28) arranged to extend in the fore-and-aft direction, in a plane view of the muffler (24) and the main stand (26).

Description

[0001] This case is a divisional application of the patent application with the application number 200880123391.9 and the invention name is Motorized Two-wheeled Vehicle technical field [0002] The present invention relates to a motorcycle including an exhaust device in which a space for expanding exhaust gas flowing in from an exhaust pipe is formed, such as a muffler and an exhaust chamber. Background technique [0003] A motorcycle has an exhaust device in which a space for expanding exhaust gas flowing in from an exhaust pipe connected to the engine is formed. For example, there is a motorcycle in which a muffler that discharges expanded exhaust gas to the outside is provided as an exhaust device, and the muffler is arranged on the side of the rear wheel, that is, the rear arm that supports the rear wheel swingably. above. In addition, there is also a motorcycle in which an exhaust chamber disposed between the engine or the part behind the engine in the body frame and ...

AI Technical Summary

Problems solved by technology

[0006] However, when increasing the displacement of the engine in a motorcycle in which the muffler is directly arranged on the exhaust pipe, it is also necessary to increase the size of the muffler in order to match the displacement of the engine.

Therefore, in such motorcycles, when increasing the displacement of the engine, since the muffler is arranged on the side of the rear wheels, the rear portion of the vehicle body is enlarged.

In addition, since the muffler is placed above the rear arm, it is difficult to achieve a low center of gravity body
