Reed Valve V-Force3 Moto Tassinari CR85

The unique design of the VForce poppet valve system includes double the poppet tip surface area compared to a conventional poppet valve design. This has two major advantages:

1) The reed petals only travel half the distance of a conventional reed valve design to achieve the same airflow.

2) Because the reed petals only need to travel half the distance of a conventional poppet valve design, there is a greater chance that they will be fully open as well as a better chance of sealing when "closed".
A reed petal never truly "closes" in the classical sense, because it is always in motion.
Consider this, an engine running at 8,000 rpm causes a reed petal to open and close 133 times in one second. This fact highlights another advantage of VForce.
