VFORCE/MOTO TASSINARI - V4X07EL - V-Force 4X Reed Valve Set with Light Tension Petal - Yamaha
Two-stroke power starts with intake efficiency, and the reed valve is the component that controls how aggressively and cleanly your engine draws in the air-fuel charge. The VFORCE/MOTO TASSINARI V4X07EL is a precision-engineered reed valve system for Yamaha engines that improves upon OEM performance through better airflow geometry, more durable materials, and an elimination of the mechanical weak points that cause OEM reeds to fail. Low tension version of VFORCE4X reed valve, part #1008-0360 (sold separately). Ideal for woods riders, hard enduro riders, tight MX tracks or any rider looking for maximum bottom-end. Material: Carbon Fiber. For riders who want cleaner throttle response and more peak power, upgrading to the V4X07EL is one of the most effective engine modifications available for a two-stroke.
