VForce Tassinari V4R26 V-Force 4 Reed Valve Set — Beta / GasGas / Husqvarna / KTM 2016-2026
Product Description
The V-Force 4 Reed Valve Set (V4R26) is the industry standard for 2-stroke performance, engineered to maximize your engine's potential. Designed for riders who demand crisp throttle response and increased power throughout the entire RPM range, this system is an essential upgrade for your Beta, GasGas, Husqvarna, or KTM dirt bike.
This system features a wider reed cage and a sophisticated resin system that provides 10.5% more reed tip area. By incorporating aerodynamically shaped central wings and longer reed stops, the V-Force 4 reduces petal tip velocity to ensure exceptional durability and a consistent, precision seal every time you grab a handful of throttle.
Top Features: VForce V-Force 4 Reed Valve Set
- Enhanced Durability: Long reed stops progressively slow reed petal tip velocity to extend the lifespan of the petals.
- Maximum Airflow: Combined reed tip area is increased by 10.5% for superior fuel/air delivery.
- Aerodynamic Design: Reduced frontal area of the central wing and airfoil-shaped cage tips increase velocity from outer ports.
- Precision Engineering: Advanced carbon fiber resin system and pre-curved petals ensure an airtight seal for optimal performance.

Frequently Asked Questions
Q: Will this reed valve set provide more low-end power?
A: Yes. The VForce 4 is designed to improve the efficiency of your engine's intake, which typically results in cleaner, snappier throttle response and increased low-to-mid range torque compared to stock reed valves.
Q: Do I need to re-jet my carburetor after installation?
A: Because the VForce 4 improves airflow significantly, it is highly recommended to check your jetting. In most cases, you may need to slightly adjust your pilot or main jet to take full advantage of the increased air/fuel flow.
Expert Pro-Tip: When installing your new VForce petals, ensure the mounting surface on your cylinder block is perfectly clean and free of old gasket material. Even a microscopic piece of debris can cause a slight air leak, which will ruin your bike's idle and tuning. Also, avoid using any liquid gasket sealers—the VForce system is designed to seal with the provided gaskets only.
