Description

The unique design of the VForce4R reed valve system for Yamaha YZ 85 features double the reed valve area of conventional reed valves. This has two advantages:

  • The reeds only open half the distance of conventional reeds to achieve the same flow.
  • By only opening halfway, there's a better chance of them being fully open and a better chance of sealing completely. By only opening halfway, they last longer as they don't experience as much pressure as conventional reeds opening as wide.

Improvements with VForce4:

  • New resin, carbon fiber and lay-up reed system
  • Pre-curved reed ensures better sealing at the tip
  • Wider reed cage for maximum mixture flow
  • Reed tip area increased by 10.5% resulting in increased total mixture flow
  • Airfoil shape added to the tip of the cage to increase air speed to external ports
  • Longer reed stops to progressively decrease the speed of the reed tip movement, for increased durability.
  • Reduced central wing front area by 15.6% combined with a more aerodynamic shape.

New VForce4R features:

  • Rubber over-mould on the reed tip surface to further improve petal life.
  • Pre-curved reed ensures a better seal at the tip.

 

ATTENTION: This product is not a direct fit for the Yamaha DT LC 50. You will need to use, for example, an Athena 115cc cylinder or open the cylinder's intake.
