This Driven Racing 525 Front motorcycle sprocket works as a bolt-on replacement for your stock sprocket. It is designed to fit the Yamaha YZF-R1M years 2015 to 2018. We recommend also replacing the drive chain when changing sprockets on your bike - remember to match up the front and rear sprockets and chain (520 with 520, 530 with 530, etc).
