V-FORCE4 V4145 Reed Valve — V-FORCE

The V-Force 4 reed valve for Yamaha YFS 200 Blaster builds on the strengths of the V-Force 3 while adding targeted improvements for reliability and responsiveness. The carbon fibre reeds, combined with a redesigned resin frame, ensure high fatigue resistance while optimizing airflow: the system delivers an airflow up to 10% greater than the original setup. The external walls protect the reeds from debris and contribute to their longevity, which is beneficial when the terrain becomes demanding.

• Materials: carbon fibre reeds, resin frame.
• Performance: airflow superior to the original (≈ +10%), for better engine velocity.
• Protection: external walls covering the reeds to limit premature wear.
• Manufacturer reference: V4145
• Usage: designed for the Yamaha YFS 200 Blaster quad (listed models: 2006-2007).

For riders seeking a sharper engine response and enhanced durability in off-road use, the V-Force 4 represents a proven solution. Be sure to check compatibility with your exact model before installation and entrust the fitting to a qualified tuner or mechanic if necessary.
