V-force 4 reed valve assembly | VFORCE/MOTO TASSINARI

Product description

Long reed stops added to progressively slow petal tip velocity, for increased petal durability Reduced frontal area of central wing by 15.6%, combined with a more aerodynamic shape Combined reed tip area increased by 10.5%, resulting in increased total airflow Rubber overmolding on reed tip surface of cage to further enhance petal life Airfoil shape added to cage tip to increase air velocity from outer ports All-new manifold, reed cage and air guide designed for the VForce4R When ordering replacement reeds, order one set per reed cage All-new reed petal resin system, carbon fiber and lay-up Pre-curved reed petal ensures better seal at tip Wider reed cage for maximum airflow
