Moto Tassinari - VForce 4X Reed Valve Light Tension Petal - Yamaha 

We like the Moto Tassinari VForce 4X Light Tension Petal Reed Valve because it transforms the Yamaha YZ250 and YZ250X into bottom-end monsters built for woods, hard enduro, and tight MX lines. The lighter tension petals snap open with less effort, delivering crisper throttle response, stronger low-end grunt, and smoother power right where riders need it most. Add in the precision pre-curved carbon fiber reeds, a widened cage for increased airflow, and aerodynamic shaping that boosts velocity, and you get a setup that not only makes the bike more responsive but also more durable. For riders clawing through rocks, threading tight singletrack, or blasting out of corners, this reed valve makes every twist of the throttle feel sharper, stronger, and more controlled. Proudly made in the USA, it’s built to perform and built to last.

Key Features:

  • Low tension version of VFORCE4X reed valve
  • Ideal for woods riders, hard enduro riders, tight MX tracks or any rider looking for maximum bottom-end
  • Advanced reed petal resin system, carbon fiber and lay-up
  • Pre-curved reed petal ensures better seal at the tip
  • Wider reed cage for maximum airflow
  • Combined reed tip area is increased by 10.5% for better airflow
  • Airfoil shape added to cage tip to increase velocity from the outer ports
  • Reduced frontal area of the central wing combined with a more aerodynamic shape
  • Made in the USA

Low quality. Recommend something from a better brand.
Low quality. Seemed fine until the first one I ordered one of the terminals broke off with very little tightening force. The replacement i had ordered worked for a few days then quit working altogether. Overall disappointed.
