Moto Tassinari's VForce tuning reed valves developed for racing provide higher airflow and better fuel/air mixture. The torque and power curve improves over the entire speed range and provides better acceleration.
The all-new VForce4 is built upon the solid foundation that has made the VForce3 such a success for the last 10 years. While the VForce3 has been continually refined over the years, this is a complete redesign of the entire system.

Details:

• All-new reed petal resin system, carbon fiber and layup
• Pre-curved reed petal ensures a better seal at the reed tip
• Wider reed cage for maximum airflow
• Combined reed tip area is increased by 10.5%, resulting in increased total airflow
• Airfoil shape added to the cage tip increases the air velocity from the outer ports
• Long reed stops added to progressively slow the petal tip velocity for increased petal durability
• Frontal area of the central wing is reduced 15.6% and combined with a more aerodynamic shape
• Note: When ordering replacement reeds, order one set per reed cage
