Trust the Moto Tassinari VForce4 reed valve system to deliver durable, reliable performance for your modern 2-stroke motocross bike. Doubling the reed tip surface area of OEM designs, this system is designed to boost horsepower and torque, whether your engine operates at 8,000 RPM or beyond. VForce4 ensures peak performance.

The new VForce4Ri utilizes a winged air guide that increases air velocity for a dramatic gain in throttle response. Paired with the new winged air guide is a custom intake manifold boot that offers a straighter shot to the intake that greatly enhances both airflow and performance. The VForce4Ri also incorporates carbon fiber per-curved reed petals designed to ensure superior reliability and maximum performance.

Features of the V-Force4 Reed Valve - Yamaha YZ85:

  • Rubber over-molded reed cages to aid in sealing to extend reed life.
  • VForce4 Reed Valve System increase torque and increases horsepower over the entire power band.
  • VForce4 Reed Valve System incorporates the industry's first and only patented snap together reed valve design. The entire assembly is completely screwed free, meaning that when reed petals need changing the job is now literally a "SNAP".
  • Newly designed reed stops for increased reed petal stability and a shorter reed cage for a noticeable performance increase due to lighter reed petals
