The Features and Benefits of VForce Technology

The Moto Tassinari VForce3 reed valve system is the number one choice of the Factory teams. Currently more Factory race teams depend on our reed valve technology than all the other brands combined.

The VForce3 valve 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 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.

Changes on the VForce3:
While the VForce3 reed valve system may look barely changed for 2004, nothing could be further from the truth. The VForce3 was developed with direct feedback from riders such as Factory Honda’s Ricky Carmichael and Factory Kawasaki’s James Stewart. There is no substitute for working with world class athletes in product development and testing. So what exactly is new and different on the VForce3? Let’s take a look.

• Symmetrical petals:
The VForce3 now uses symmetrical reed petals. No longer will you need to be concerned with having both “inner” and “outer” reed petals.

• Super quick petal changes:
The VForce3 incorporates the industry’s first and only patented snap together reed valve design. The entire assembly is completely screw free, meaning that when reed petals need changing the job is now literally a “SNAP”.

• Custom air guides:
Custom air guides specific to each individual application ensure the maximum airflow and benefits of the VForce3 reed valve system in your motorcycle or ATV.

• Advanced composite technology:
The VForce3 utilizes an advanced composite technology with an all new carbon fiber lay-up and resin system. This new lay-up was designed entirely around the reed cage design of the VForce3 for superior performance and response.

• Redesigned reed stops:
A new improved reed stop design completely eliminates the need for retaining screws. This new feature now removes any possible chance of a failure.

• Airfoil technology:
Airfoil shaped (flat on bottom/curved on top) reed tip surface increases velocity of fuel/air mixture as it passes through, creating the optimum fuel atomization.
