Product Detail
Specification:
[Manufacturer Part no.] V4R82B-I
[Description]
Moto Tassinari's VForce Reed Valve Systems have been a reference for specialists in the preparation of 2-stroke engines for more than 10 years. VForce4Ri Reed Valvex increase engine power and gas reactivity by improving the efficiency of the intake system compared to the original reed valves Standard Vforce reed valve features:
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
Reduced reed petal wear
Screw free design eliminates risk of screws going through motor
Screw free design enables rapid reed petal changes
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
New Vforce4Ri features :
Rubber overmodling on reed tip surface of cage to further enhance petal life
Custom intake manifold boot that offers a straighter shot to the intake that greatly enhances both airflow and performance
