Yamaha R3 - Select front and rear sprocket sizes from the options chart. 415 Conversion Kit converts your stock 520 chain and sprockets to 415 Sizes. On average a weight savings of 2 LBS. Kit includes your choice of sprocket, chain with rivet link, locking tab washer and nut.
Our 415 counter shaft sprocket is designed with the Professional in mind. No more stripped out counter shafts our nuts that come loose. Just replace the stock nut, washer and sprocket with our special precision counter shaft sprocket, special nut, reusable bend over locking tab washer and it makes gearing changes a breeze.
DID ERZ 415 Chain from Graves comes with a rivet master link and is 144 links long. Addition master links and custom lengths are available.
This custom 415 rear sprocket is made for Graves by Vortex. This sprocket is Preston machined and hard anodized for long life. It also has the mounting area machined down to accept the short receiver studs and thin 10mm lock nuts just like on all of our race bikes. The advantages from these modifications are reduced rotating weight and improved clearance when changing the wheels.
