Description

technical field

[0001] The present invention relates to motorcycle components, especially motorcycle mufflers. Background technique

[0002] At present, the common structure of motorcycle mufflers equipped with CG125 and CG150 engines is as follows: figure 1 , figure 2 As shown, the muffler cylinder 1 is a single-layer structure, and the inner cavity of the muffler cylinder 1 is divided into several muffler chambers by partitions. There is a baffle at the end of the inner connection pipe 2 located in the first muffler chamber, and it is close to The pipe wall of the inner connection pipe of the baffle is provided with radial exhaust holes, the partition between the first and second anechoic chambers is a porous plate, and the rest of the anechoic chambers are communicated through the air guide pipe 9, and the gas finally Discharged from the tailpipe.

[0003] The motorcycle muffler of this structure has the following defects in use:

[0004] 1. Since the muffler cylinde...
