The RAD Valve Block Cage Kit is designed for the Yamaha YZ85 (2002-2019). Featuring carbon fibre reeds, it enhances engine performance by improving airflow, increasing horsepower, and reducing reed petal wear. The screw-free design allows for quick reed changes and eliminates the risk of screws entering the motor. It also boasts a pre-curved reed petal for better sealing, wider reed cage for maximum airflow, and improved aerodynamics.
