RENTHAL Aluminium Ultra-Light Self-Cleaning Rear Sprocket 121U - 420 for Yamaha YZ65 121U-420-47GBSI

Renthal Ultralight™ Self-Cleaning Rear Sprocket

• Machined with great precision in a light and durable 7075 T6 aluminum.
• A profile designed for the teeth that facilitates the evacuation of the mud and minimizes power losses due to friction between the chain and the rear sprocket

Anodizing hardens the surface material and improves aesthetics. Bores are made on the sprocket at strategic locations to lighten the piece without reducing resistance.

This rear sprocket will bring you a gain in weight, power, resistance and longevity. An asset for the MX, SX or enduro.
