Vforce 4RI Membranblock KlappenkastenRef : VF00019A / 1009785

Moto Tassinari's VForce Reed Valve Systems have been a reference for specialists in the preparation of 2-stroke engines for more than 10 years. VForce4Ri Reed Valvex increase engine power and gas reactivity by improving the efficiency of the intake system compared to the original reed valves

Improved Vforce4 features :

• 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
• Combined reed tip area increased by 10.5% resulting in increased total air flow
• Airfoil shape added to cage tip to increase air velocity from outer ports
• 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

New Vforce4Ri features :

• Rubber overmodling on reed tip surface of cage to further enhance petal life
• Custom intake manifold boot that offers a straighter shot to the intake that greatly enhances both airflow and performance
