Mototassinari VForce4Ri reed valve pack Yamaha YZ65 2018-2024

The V-Force4Ri reed valve pack for Yamaha YZ65 2018-2024 represents the pinnacle of innovation in the reed valve system sector for engines. Building on the renowned success of the VForce3, which has dominated the market for over fifteen years, the VForce4 represents a revolutionary redesign of the very concept of the lamellar system.

Advanced Soul Cage Design: The wing shape in the reed tip area accelerates airflow from the external ports, maximizing motor efficiency. Thanks to a new cane petal resin, carbon fiber and layering system, the new pre-curved petals offer superior hold in the tip area.

Improved Durability and Resistance: Longer reed stops progressively slow the speed of the petal tip, ensuring greater durability over time. With a 10% increase in combined reed tip area, you get a noticeable overall increase in airflow.

VForce4Ri represent the latest frontier in optimizing air flow and engine performance. With a custom intake manifold boot, these models offer a straighter hit to the intake, which results in a noticeable improvement in airflow and overall engine performance.
