Description
V Force 4X Reed Valve System KTM / Husqvarna / Gas Gas 150cc-300cc
Building on the legacy of the VForce4R, the VForce4X represents a complete overhaul. It introduces an innovative reed cage with an airfoil shape at the tips for enhanced air velocity, paired with a new reed petal resin, carbon fiber and a novel lay-up methodology for the pre-curved petals, ensuring superior sealing. This model also boasts longer reed stops to decelerate petal tip velocity, enhancing durability. With a more than 10% increase in the combined reed tip area, it achieves a significant boost in airflow. Additionally, the VForce4X showcases a 15.6% reduction in the frontal area of the central wing, matched with an aerodynamically optimized shape, highlighting its commitment to advancing performance through design innovation.
