Why do motorcycle transmission systems use sprockets and chains instead of gears?

1SprocketThe chain is non-conjugated meshing, which makes the machining and installation accuracy of the chain drive much lower than that of the gear drive

2 chain drive can meet the requirements of large center distance, if gear drive is used, it may involve the gear train

3 Compared with gear drive, chain drive is lighter

4 Compared with gear drive, chain drive has better shock absorption performance
