V-Force / Moto Tassinari

V-Force (Moto Tassinari) is the American specialist in reed valve systems for 2-stroke engines — number one on the market when it comes to more power and better response. V-Force 3, 4 and 4X reeds use a composite cage with a dual-stage folded geometry that significantly increases petal area compared to the original. The result is stronger midrange pull, a faster reaction to the throttle and smoother running across the whole rev range, with no need for further modifications. The complete assembly fits as a direct replacement for the original and lasts for years of hard use.
