When racers looking for the performance edge on two-stroke race bikes. The VForce3 reed valve system for all modern 2stroke motocross you will increase horsepower and torque by increasing the efficiency over a conventional reed valve design. VForce3 reed cage offers a unique design features double the reed tip surface over the OEM reed valve design.
Moto Tassinari design is superior, consider when an engine operating at 8,000 RPM the reed petal opening and closing 133 times in one second. That is demanding on the VForce3 reed system, reliability and performance are what you need from your reeds. This is where the Moto Tassinari VForce3 system outperforms the competition. Since the petals are only traveling half the distance, they last longer over the OEM Designed reed valve design.
Moto Tassinari used the proven success of the VForce3 and have taken the performance even father with the VForce4. The VForce3 has been receiving constant updates and improvement to its design (including the latest VForce3R models). The VFroce3 has been a success when it comes to performance but after 15 years it was time to move forward.
The new VFroce4 reed cage design now incorporates an airfoil shape at the reed tip area to increase air velocity from the outer ports. Moto Tassinari used an all-new reed petal resin system, carbon fiber and lay-up on their new pre-curved reed petals. Why does VForce4 use pre-curved reeds, the benefit of the pre-curved reed petal is better sealing at the tip area. The VForce4 also features longer reed stops to progressively slow petal tip velocity, for increased petal durability. The combined reed tip area has been increased by over 10% resulting in increased total airflow. Finally, they reduced frontal area of central wing by 15.6% combined with a more aerodynamic shape.
The all-new VForce4R models incorporate a rubber overmodling on the reed surface to drastically increase reed petal life, while also creating a superior sealing surface.
The all-new VForce4Ri models include a custom intake manifold boot that offers a straighter shot to the intake that greatly enhances both airflow and performance. The VForce4Ri is currently only available for select bikes and atv’s.
