V-Force V-Force 3 valve box - Yamaha JET

Product details

Moto Tassinari's VForce reed valves have been the benchmark for 2-stroke engine tuning specialists for over 10 years. VForce 3 reed valves increase engine power and throttle response by improving the efficiency of the intake system compared to the original valves.

• Double the contact surface compared to original valves
• Increases performance across the entire engine speed range: low speed, mid-speed, and high speed
• More efficient system thanks to stiffer valves
• Increased airflow = increased power
• Highly resistant valves, reduced wear
• Screwless construction: reduced risks and quick valve changes
