Genuine V-Force 4 Reed Valve Assembly.
- Double the reed tip surface over a conventional reed valve design
- Increased bottom end, stronger mid-range and longer top-end
- Greater efficiency due to reduced reed petal travel
- More airflow means more horsepower
- Reduced reed petal wear
- All-new reed petal resin system, carbon fiber and lay-up
- Pre-curved reed petal ensures better seal at tip
- Wider reed cage for maximum airflow
- Combined reed tip area increased by 10.5% resulting in increased total air flow
- Airfoil shape added to cage tip to increase air velocity from outer ports
- Long reed stops added to progressively slow petal tip velocity, for increased petal durability
- Reduced frontal area of central wing by 15.6% combined with a more aerodynamic shape
