The VFORCE/MOTO TASSINARI V-Force 4 Reed Valve Set (Part Number: V417A) is engineered to deliver superior performance and durability for Beta and KTM motorcycles. This advanced reed valve system features long reed stops that progressively slow petal tip velocity, significantly enhancing petal durability and extending component lifespan. The design reduces the frontal area of the central wing by 15.6%, combined with a more aerodynamic shape that minimizes air resistance and improves overall airflow efficiency. Additionally, the increased reed tip area by 10.5% contributes to higher total airflow, resulting in improved engine response and power output. Rubber overmolding on the reed tip surface provides enhanced petal life by protecting against wear and tear during operation. The airfoil shape added to the cage tip increases air velocity from outer ports, optimizing airflow dynamics for better throttle response. The all-new manifold, reed cage, and air guide are specifically designed for the VForce4R, ensuring seamless integration and maximum performance. When ordering replacement reeds, it is recommended to purchase one set per reed cage to maintain optimal operation. The reed petals are constructed with a new resin system utilizing carbon fiber and lay-up techniques, offering increased strength and resilience. The pre-curved reed petal design ensures a better seal at the tip, reducing air leakage and improving efficiency. The wider reed cage allows for maximum airflow, contributing to enhanced engine power and responsiveness. Made in the USA, this reed valve set combines innovative engineering with high-quality materials to meet the demands of competitive and recreational riders alike.
