V-Force 4 Reed Valve System


The VForce4 is built upon the solid foundation that has made the VForce3 such a success over previous years. While the VForce3 has been continually refined over the time, this is a complete redesign of the entire system. The only thing Moto Tassinari didn't change is the bolt pattern. All the components that go into making a VForce reed valve system have been significantly changed since the VForce3 for more power, better throttle response and a better ride.

  • 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 with a more aerodynamic shape
  • Each unit ships with reeds, reed cage and all required gaskets
  • Made in the USA

If I bore out my blaster 200 to a 249 do I have to buy a different one or can I still get this one?

Yes, you would still be able to use this system.
