Yamaha YFZ 450 R Camshaft Chain Kit - Hot Cams - Silent - '09-'21. This Hot Cams silent camshaft chain kit is designed specifically for the 2009–2021 Yamaha YFZ 450 R (450cc) to deliver durable, low-noise timing chain performance.

The kit is engineered to meet and in many areas exceed OEM expectations for wear resistance and longevity. Heat-treated links provide improved friction and impact resistance to reduce chain stretch over time, while an advanced stamping method increases contact with the sprocket for more consistent engagement. The silent-chain design reduces operational noise compared with conventional roller chains, making it a practical upgrade for riders focused on reliability and quieter running without altering engine components.
