Moto Tassinari VForce4R V4R04 Reed Valve Yamaha YZ125 2005-2017

The unique design of the VForce reed valve system has twice the reed tip surface than traditional reed valve designs. This has two major benefits: 1) The reed petals only travel half the distance for airflow similar to traditional reed valve designs. 2) In traditional reed valve designs, the reed petals only have to travel half a distance, making them more likely to fully open and more likely to seal when "closed." The reed petals never truly "close" in the classical sense, as they are always in motion. Think about it, an engine running at 8,000 RPM opens and closes the reed petals 133 times in one second. This fact highlights another VForce advantage. Because the petals only travel half the distance, they experience less wear than the reed petals in traditional reed valve designs. Standard VFORCE Reed Valve Features Doubles the reed tip surface than traditional reed valve designs, strengthening the bottom end, strengthening the midrange, and lengthening the top end. Increases efficiency by reducing reed petal movement, increases air flow, reduces reed petal wear, and eliminates the risk of screws passing through the motor Screw-free design quickly removes reed petals You can change it.
