The Boyesen RC2 Series Rad Valve is a model-specific performance component engineered to enhance horsepower and throttle response on the Yamaha YZ250/250X, KTM 65SX, and Kawasaki KX85/100. Each unit is tailored to the specific model, year, and displacement of the motorcycle, ensuring precise compatibility. By redirecting the intake charge for more even distribution to the intake ports, the valve maintains constant flow velocity, which directly contributes to improved engine output and immediate throttle feedback.
Constructed with a one-piece design, the RC2 Series Rad Valve offers a streamlined solution for riders seeking to optimize their air intake system. The component is designed for easy installation, allowing for a straightforward upgrade process without complex modifications. This focused engineering approach ensures that the valve integrates seamlessly with the existing intake geometry to deliver consistent performance gains.
