The all-new VForce4 is built upon the solid foundation that has made the VForce3 such a success for the last 10 years. While the VForce3 has been continually refined over the years, this is a complete redesign of the entire system. We jokingly say, "The only thing we didn't change is the bolt pattern." However this is actually quite true. All the components that go into making a VForce reed valve system have been significantly changed since the VForce3.
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". A reed petal never truly "closes" in a classic sense, as it is always in movement. Consider this, an engine operating at 8,000 RPM results in a reed petal opening and closing 133 times in one second. This fact, sheds light on another VForce advantage. Since the petals are only traveling half the distance, they generally last longer as they receive less wear than the reed petals on a conventional reed valve design.

Moto Tassinari manufactures the AIR4ORCE adjustable intake system for four-stroke bikes and the VForce reed valve system for two-stroke motorcycles in the United States.
A VForce reed valve system increases bottom-end power while also improving mid-range and top-end performance. It also allows for increased airflow, which results in increased horsepower.
For almost a decade, Moto Tassinari's VForce reed valve system has been the reed valve system of choice for anyone serious about two-stroke engine performance. The VForce3 reed valve system is based on the simple idea that it will make the engine more powerful and the throttle more responsive by making it more efficient than a standard reed valve.
The VForce reed valve system's unique design provides twice the reed tip surface of a typical reed valve. This has two significant advantages:
1) The reed petals travel approximately half the distance required by a normal reed valve design to produce the same amount of airflow.
2) Because the reed petals travel only half the distance required by a traditional reed valve design, there is a greater possibility of them being fully opened as well as a greater chance of sealing when they are "closed." A reed petal never completely "closes" in the traditional sense, because it moves all the time and never stops.
The VForce3 also has a completely screw-free design, which means there are no loose screws, or worse, screws that go through your engine and cause damage. Because screws aren't used, reed petal changes can be done very quickly.
Vivid Racing includes a wide collection of Moto Tassinari products such as the VForce3R Reed Valve System, VForce2R Replacement Reed Petals, System Arctic Cat, VForce4R Replacement Reed Petals, and Reed Gasket for different models of motorbikes.
