The Moto Tassinari VForce3 reed valve system is often times the number one choice of users looking to improve the performance of their machine. It’s a true “bolt-on” performance modification. If you’ve ever checked your reed petals for wear (which you should be doing once a year) than you can install a VForce3 Reed Valve System.
The VForce3 Reed Valve System incorporates features you won’t find with other system on the market. With such features as twice the reed tip surface, radius cage surface, snap-together construction, proprietary carbon fiber recipes and more. By doubling the reed tip surface the petals now only need to open half as far to have 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. This design also enables the valve to drastically improve the entire powerband with a significant boost in the bottom and mid. Instant throttle response is an understatement! The petals now sit on a radius surface to create a “pre-loading” effect that improves an already snappy acceleration. Our new cage design now allows the reed petal tips to be recessed into the cage itself. This allows for a cushioning of the reed tips and also discourages the possibility of any back-flow.
