Moto Tassinari VForce4 Reed Valve 2018-2022 Yamaha YZ65 V4R82B-I

Why does the new YZ85 VForce4Ri outperform standard reed cage systems?

The main reason is by having the reed cage configured in and dual v-shaped cage it doubles the reed surface area. This increased reed surface area allowing an increase of air flow. The reeds this travel less, which ensure the reeds opening and closing fully.  The “R’ cages have a rubber pad area for the reed tips to land on to improve reed life. The reed pedals are constructed from carbon fiber and are light weight and stronger than conventional fiber reeds.

The new YZ85 VForce4Ri reed system now includes a new performance intake boot this offers a straighter shot into the reed cage. The new intake boot will increase the airflow and performance over OEM intake boots.

Features of the VForce4 Reed Valve - Yamaha YZ85:

• 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
