The VForce3 reed valve system by Moto Tassinari incorporates features
you won't find with other system on the market. With such features as
twice the reed tip surface, radius cage surface and more. By doubling
the reed tip surface (over a stock standard valve design) the petals now
only need to open half as far to provide the same flow as a stock style
cage. This is a significant advantage when you factor in that a reed
petal opens and closes 133 times per second at 8,000 rpm. The petals are
only traveling half the distance of a stock style cage, so now fatigue
to the petal has been greatly reduced, increasing petal life.
