VForce

The unique design of the VForce reed valve system features double the reed tip surface over a conventional reed valve design. This has two major benefits:

  1. The reed petals only travel half the distance as a conventional reed valve design to get the same airflow.
  2. Because the reed petals only need to travel half the distance of that on a conventional reed valve design, there is a greater chance of them being fully opened as well as a better chance of sealing when they are "closed".
While a VForce reed valve system offers increased bottom end, stronger mid-range and longer top-end, it also allows more airflow which means more horsepower.
