V-Force 3 Reed Valve System

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 years. The simple premise of the VForce3 reed valve system is to increase engine power and throttle response by increasing the efficiency over a conventional reed valve design.

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 super quick reed petal changes
Each unit ships with reeds, reed cage and all required gaskets
Made in the USA

Great

Adds power and really wakes up the bike!

Great buy!

In back to back comparisons with the OEM reed valve my son said his KTM 65 pulled stronger out of corners and also had better top speed on the long straights.

Great product- V-Force3 reed box 03 CR250R. Smooooth power. What a difference. Paired with PC national pipe/spark arrester.

Works better than the old reeds.

The ride is 80 percent better.

Perfect fit.

I ordered this from another website and 7 days later the reeds still hadn't shipped. Cancelled that order after I found the exact same reeds cheaper on here and got them really quick even with the covid-19 scare going on. These were the cheapest I could find. Would highly recommend.

Answer Question

Can someone please show me what manifold boot I need for this.does it work with the stock manifold?

By Justin

V-Force 3 Reed Valves work with the stock intake components on any machine you select from our fit guide. If your machine's intake components are otherwise stock, you should have no problem fitting this to your machine.
