Motorcycle

Abstract

The motorcycle of the present invention suppresses thermal damage of heat from a catalytic device to a starter motor. The motorcycle is provided with: a body frame (2); an engine (9) that is supportedby the vehicle body frame (2); the engine (9); an exhaust pipe (86) that discharges the exhaust gas discharged from the exhaust port (60) of the engine (9); the exhaust pipe (86); a catalytic device(81) that is provided inside the exhaust pipe (86) and that is disposed in front of the engine (9), the catalytic device (81); and a starting motor (13), the starting motor (13) is arranged in front of the engine (9). The vehicle body frame (2) is provided with a lower frame (23) which extends downward from the head pipe (21), and when viewed from the front of the vehicle, a starting motor (13) isdisposed on one side in the left-right direction of the lower frame (23), and a catalytic device (81) is disposed on the other side in the left-right direction of the lower frame (23).

Description

technical field [0001] The present invention relates to a motorcycle equipped with a catalytic device for purifying exhaust gas. Background technique [0002] Conventionally, a motorcycle has an exhaust pipe through which exhaust gas discharged from an exhaust port of an engine flows, and a catalytic device for purifying the exhaust gas is provided in the exhaust pipe. In recent years, in order to comply with regulations on exhaust gas, it has been required to improve the purification performance of catalytic devices with respect to exhaust gas. In order to satisfy such a request, it is important to dispose the catalyst device as far upstream as possible from the exhaust pipe. Therefore, the catalyst device may be disposed in front of the engine in some cases. [0003] For example, Patent Document 1 discloses that at least a part of the catalyst device is located in front of the crankcase when viewed from the side of the vehicle.

Problems solved by technology

For example, there is a situation in which a starter motor to start the engine is arranged in front of the engine. When the distance between the starter motor and the catalytic device is too close, the starter motor may be thermally damaged due to the heat from the catalytic device, and the starter motor may be damaged due to heat from the catalytic device. reduced performance of
