VFORCE/MOTO TASSINARI - V-Force4X Reed Valve Set 1997-2024 Yamaha YZ250 and YZ250X

Introducing the VFORCE4X, designed for 1997-2024 Yamaha YZ250 and YZ250X motorcycles. This reed valve system provides unparalleled durability and addresses the limitations of the stock system.

For over 25 years, the VForce reed valve system from Moto Tassinari has been the top choice for those seeking optimal performance in two-stroke engines. By doubling the reed-tip surface, this system increases efficiency and delivers greater engine power and throttle response when compared to traditional reed valve designs.

MOTO TASSINARI - VForce4X Reed Valve System:

• V-Force4X Reed Valve System increases torque and increases horsepower over the entire powerband.
• V-Force4X Reed Valve System incorporates the industry's first and only patented snap-together reed valve design. The entire assembly is completely screwed free, meaning that when reed petals need changing the job is now literally a "SNAP".
• Newly designed reed stops for increased reed petal stability and a shorter reed cage for a noticeable performance increase due to lighter reed petals
