Moto Tassinari VForce4 Reed Valve - V4R82B-I - 2018-2023 Yamaha YZ65

Experience unparalleled performance and reliability with the Moto Tassinari VForce4 reed valve system. Designed for modern 2-stroke motocross bikes, this innovative system increases horsepower and torque by doubling the reed tip surface over OEM designs. No matter if your engine operates at 8,000 RPM or higher, trust VForce4 to provide the durability and performance you need.

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 VForce4 Reed Valve - Yamaha YZ65:
  • 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
  • Yamaha YZ65 2018-2023
The “R’ cages have a rubber pad area for the reed tips to land on to improve reed life.
