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. Features: Advanced reed petal resin system, carbon fiber and lay-up Pre-curved reed petal ensures better seal at the tip Wider reed cage for maximum airflow Combined reed tip area is increased by 10.5 for better airflow Airfoil shape added to cage tip to increase velocity from the outer ports Long reed stops added to progressively slow reed petal tip velocity for increased petal durability Reduced frontal area of the central wing combined with a more aerodynamic shape Replacement reeds available Made in the USA Note: Images are for reference only, actual product will vary based on make and model.
