For over 25 years, the VForce reed valve system from Moto Tassinari has been the top choice for those seeking improved performance from their two-stroke engines. Its innovative design doubles the reed-tip surface to enhance engine power and throttle response, making it a must-have for serious riders.

VFORCE/MOTO TASSINARI - V-Force 4X Reed Valve System:

• Rubber over-molded reed cages to aid in sealing to extend reed life.
• 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
