V-Force 4X Reed Valve Assembly for 2-Stroke Engines (V4X26AM-I)

Description

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.

• The V-Force 4X has a newly designed reed valve that achieves the same extended reed petal life of the V-Force 4R. This is achieved through an all-new reed cage surface design and reed petal combination that increases reed petal life.
• For select Yamaha YZ250 and YZ250X motorcycles this has been designed to offer you exceptional durability and overcome the shortcomings of the stock reed valve system.
