The wait is finally over, as Moto Tassinari introduces the all-new VForce4 for the Yamaha Banshee and Blaster ATVs. The Yamaha Banshee was chosen to be at the front of the line for VForce4 introduction as it continues to be our most popular off-road application to date.

 

The VForce4 reed valve system is entirely new. The only carry-over from the VForce3 is the bolt pattern. Some of the major updates are listed below:

 

All-new reed petal resin system, carbon fiber and lay-up Pre-curved reed petal ensures better seal at tip Wider reed cage for maximum airflow Combined reed tip area increased resulting in increased total air flow Airfoil shape added to cage tip to increase air velocity from outer ports Long reed stops added to progressively slow petal tip velocity, for increased petal durability Reduced frontal area of central wing by 15.6%, combined with a more aerodynamic shape

 

Independent dyno testting has repeatedly shown significant performance gains over the already outstanding performance provided by the VForce3 reed valve system.
