2x VForce4 Reed Valve System RXZ/Y125Z/Y125ZR MotoTassinari Yamaha OEM Version

  
2x - Yamaha VForce4 Reed Valve System RXZ/Y125Z/Y125ZR MotoTassinari OEM Version. 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. Double the reed tip surface over a conventional reed valve design.

Increased bottom end, stronger mid-range and longer top-end. Greater efficiency due to reduced reed petal travel. More airflow means more horsepower. Screw free design eliminates risk of screws going through motor.

Screw free design enables super quick reed petal changes. NEW AND IMPROVED VFORCE4 FEATURES. 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 by 10.5% 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. Includes:Installation instructions, complete VForce4 reed valve system (including two reed valves with reed petals) and gaskets. Yamaha RXZ135 RX135 YZ125 DT175. Also may fit:Yamaha RD RD250 RD350 RD400. THIS IS OEM VERSION, NOT ORIGINAL. Your satisfaction is our top priority.
