V Force 4X Reed Valve System KTM / Husqvarna / Gas Gas 150cc-300cc 2024-2025 Installation

V Force 4X Reed Valve System KTM / Husqvarna / Gas Gas 150cc-300cc

The VForce4X stands on the strong legacy of the VForce4R reed valve system, renowned for its impressive performance enhancements. This latest iteration represents a comprehensive overhaul, featuring innovative changes in every aspect of design and materials. It boasts an airfoil-shaped reed cage at the tip area, engineered to accelerate air from the exterior ports and amplify volumetric efficiency. Incorporating an entirely new resin combination for the reed petals, the VForce4X utilizes an advanced carbon fiber construction, complete with a pre-curved layout. This promotes optimal sealing at crucial stages of operation and maximizes petal endurance, thanks to extended reed stops that judiciously decelerate petal tip velocity. As a result, airflow has surged by over 10% due to the expanded reed tip area. The redesign also achieves a 15.6% reduction in the frontal area of the central wing, coupled with a refined, more streamlined shape for a noticeable performance gain. The VForce4X is tailor-made for enthusiasts seeking that extra edge in throttle response and efficiency.

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
