Exhaust system for motorcycle multiple cylinder engines

摘要

In an exhaust system for motorcycle multiple cylinder engines in which the downstream end of a choke pipe 41 connected to the downstream end of at least one of a plurality of exhaust pipes 22, 23 is inserted into at least one of a plurality of individual pipe portions 24a, 24b of a confluence exhaust pipe 24, the dimensional accuracy of the choke pipe 41 can be improved regardless of the exhaust pipes 22, 23 and the design of the choke pipe 41 alone can be changed, thereby making it possible to enhance the degree of design freedom. The choke pipe 41 which is separate from the exhaust pipes 22 and 23 is fixed to the downstream end of at least one exhaust pipe 22.
