Graves High Precision Cam Chain Tensioner Yamaha R3 / MT-03

Graves Motorsports High Precision Cam Chain Tensioner Yamaha R3

Graves Cam Chain Tensioners were professionally developed under strict guidelines for use in the Graves Yamaha factory race bikes. It is machined from aerospace materials and features a fine thread that allows for micro-adjustability. 

The Yamaha OEM cam chain tensioner is automatic and hydraulic, though great for everyday riding it is not the best for racing applications. The stock automatic tensioners can fail and hydraulic pressure can be inconsistent under race conditions. The Graves Cam Chain Tensioner eliminates these possible failures and allows you to fine-tune the tension and keep in within the set parameters.
