Moto Tassinari V417A V-Force 4 Reed Valve System

All-new design. Has all-new reed petal resin system, carbon fiber and lay-up. Pre-curved reed petal ensures better seal at the tip. Wider reed cage for maximum airflow. Combined reed tip area is increased by 10 1/2% for better airflow. Airfoil shape added to cage tip to increase velocity from the outer ports. Long reed stops added to progressively slow reed petal tip velocity for increased petal durability. Reduced frontal area of the central wing combined with a more aerodynamic shape. Replacement reeds sold one set per reed cage.
