Collection: VFORCE

The VForce reed valve system by Moto Tassinari has been the reed valve system of choice by anyone serious about two-stroke engine performance for the last 25+ years. The simple premise of the VForce reed valve system is to increase engine power and throttle response by increasing the efficiency over a conventional reed valve design by doubling the reed-tip surface.

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

ALL-NEW VFORCE4R FEATURES
Rubber overmodling on reed tip surface of cage to further enhance petal life
Pre-curved reed petal ensures better seal at tip
