Description

Unlock your CR500R’s true potential with the Moto Tassinari VForce3 Reed Valve System, the proven upgrade trusted by racers and tuners worldwide. The VForce3 reed valve design features a unique double-reed cage system that increases airflow velocity and efficiency, resulting in more power, better throttle response, and smoother delivery across the entire RPM range.

Built to handle the demands of big-bore two-stroke engines like the legendary CR500R, the VForce3 system improves fuel atomization, reduces turbulence, and enhances torque without sacrificing reliability or low-end response.
