Motorcycle including an exhaust system

摘要

An exhaust system (10) of a motorcycle (1) comprises front exhaust pipes (11) connected with front cylinders (14a) of a V-type engine (14) and joined to the front part of an exhaust chamber (13). Rear exhaust pipes (12) connected with rear cylinders (14b) of the engine (14) are joined to the upper part of the exhaust chamber (13). Both exhaust gases discharged from the first exhaust pipes (11) and the rear exhaust pipes (12) are unified within the exhaust chamber (13), and a catalyst (16) is disposed in the vicinity of the unifying section. The length of the rear exhaust pipes (12) is shorter than the length of the front exhaust pipes (11). High-temperature exhaust gas is introduced to the catalyst (16) contained within the exhaust chamber (13) via the rear exhaust pipes (12).
