V-FORCE 4 REED VALVE SET KTM SX/ HUSQVARNA TC 85 2003-2025

VForce Reed Valve System: Enhanced Performance and Durability

The VForce reed valve system boasts a unique design that doubles the reed tip surface compared to conventional reed valve designs. This innovation offers two major benefits:

1. Reduced Travel Distance: Reed petals travel only half the distance of conventional designs, ensuring the same airflow.
2. Improved Sealing and Longevity: With reduced travel distance, reed petals have a better chance of fully opening and sealing, resulting in longer lifespan due to less wear.

Consider this: at 8,000 RPM, a reed petal opens and closes 133 times per second. The VForce design minimizes wear, enhancing durability.

Standard VForce Reed Valve Features:

• Double the reed tip surface
• Increased bottom end, stronger mid-range, and longer top-end
• Greater efficiency with reduced reed petal travel
• More airflow for increased horsepower
• Reduced reed petal wear
• Screw-free design eliminates risk of screws entering the motor
• Rapid reed petal changes with screw-free design

Improved VForce4 Features:

• New reed petal resin system, carbon fiber, and lay-up
• Pre-curved reed petal for better seal at the tip
• Wider reed cage for maximum airflow
• 10.5% increase in combined reed tip area for more airflow
• Airfoil shape added to cage tip for increased air velocity
• Long reed stops for increased petal durability
• Reduced frontal area of central wing by 15.6% with a more aerodynamic shape

All-New VForce4R Features:

• Rubber overmolding on reed tip surface for enhanced petal life
• Extended reed petal stops
• Pre-curved reed petal for better seal at the tip
