In this category you will find all the spare sprockets we can have for your YAMAHA YFM, RAPTOR, WARRIOR, GRIZZLY,... quad of brand AFAM, DID, PBR,... available in several size and quality. It is important to maintain your transmission properly. The teeth of your crown wheel must not be too thin and the hollow of the links must not be too ovalized to guarantee a good transfer of power from the engine to your wheel. A crown in bad condition could unfortunately do a lot of damage in case of breakage. We advise to change the crown every 20 hours
