V Force 4X Reed Valve System KTM / Husqvarna / Gas Gas 125cc-300cc

The VForce4X is built upon the solid foundation that made the VForce4R reed valve system such a success. While the VForce4R has been continually refined over the years, this is a complete redesign of the entire system. All the components that go into making a VForce reed valve system have been significantly changed since the VForce4R. The reed cage design now incorporates an airfoil shape at the reed tip area to increase air velocity from the outer ports. The Vforce4X also uses an all-new reed petal resin system, carbon fiber and lay-up on the pre-curved reed petals. The benefit of the pre-curved reed petal is better sealing at the tip area. The VForce4X also features longer reed stops to progressively slow petal tip velocity, for increased petal durability. The combined reed tip area has been increased by over 10% resulting in increased total airflow. Finally, the Vforce4X features a reduced frontal area of central wing by 15.6% combined with a more aerodynamic shape.
