The VFORCE/MOTO TASSINARI V-Force 4 Reed Valve Set V417A is designed for select Beta and KTM applications. It features an all-new manifold, reed cage, and air guide designed for the VForce4R system, along with a wider reed cage intended to maximize airflow.
Long reed stops progressively slow petal tip velocity to help increase petal durability. The reed cage includes rubber overmolding on the reed tip surface to further enhance petal life, while an airfoil shape at the cage tip is designed to increase air velocity from the outer ports. The central wing has a reduced frontal area and a more aerodynamic shape, and the combined reed tip area is increased to help improve total airflow.
The set uses an all-new reed petal resin system, carbon fiber, and lay-up. Pre-curved reed petals help provide a better seal at the tip. The V417A is made in the USA. Distributor part number: V417A. Manufacturer part number: V417A.
