Chiaravalli Rear Sprockets - Yamaha

** Please do not order any sprocket by description alone. Check the application listing and order your sprocket by product code. If you have any doubts, please ask first. **

As original equipment manufacturers for famous brands such as Ducati and MV Agusta, Chiaravalli remains the first choice for replacing or upgrading your motorcycle’s sprockets. For specific application for your bike please click on the link under resource downloads below. If your bike isn't listed, get in touch as we may have old stock to suit older bikes. Alternatively, if you can’t find the right size or model, Chiaravalli also produces blank sprockets which we can supply for you to have cut to fit.
