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 10+ 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.

The unique design of the VForce reed valve system features double the reed tip surface over a conventional reed valve design. This has two major benefits: 1) The reed petals only travel half the distance as a conventional reed valve design to get the same airflow. 2) Because the reed petals only need to travel half the distance of that on a conventional reed valve design, there is a greater chance of them being fully opened as well as a better chance of sealing when they are "closed". A reed petal never truly "closes" in a classic sense, as it is always in movement. Consider this, an engine operating at 8,000 RPM results in a reed petal opening and closing 133 times in one second. This fact sheds light on another VForce advantage. Since the petals are only traveling half the distance, they generally last longer and they receive less wear than the reed petals on 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.

Awesome!

This product does exactly what you buy and some. My throttle response is is amazing and sounds throaty which is also cool. They were easy to install on my 2001 YZ125. The shipping was great like always and like always showed up couple of days early. I can't wait to go riding this weekend!

Not a quick bolt in.........

V Force almost made a reed cage that wasn't worth the trouble.
On my 2002 ktm sx250, you have to cut the reeds off flush on
the stock Boysen block. File, cuss, and fab up a carb adaptor.
Good reeds, for the money, it should be a straight bolt in.

VForce 3 Reed Valve System

Somewhat easy to install. The existing air boot for the KX85 & kx100 will need to be trimmed, which a template plate is provided in the kit. I does mention this in the detailed instructions as a possible task/
Be sure to adjust your jetting, the V Force will make the bike run leaner. I had to increase the main jet from 138 to 142.

Great product and provides additional power throughout the throttle range.

Increased mid range hit

I freshened the top end of my 02 yz 250 and added the v force 3 reed.
I have noticed an increase in my mid range. So far, happy with the installation and performance.

GREAT PRODUCT

I have noticed a big difference of how crisp it is now and how responsive my throttle is now. Couldn't ask for a better performance item. It gives you instructions on how to modify the carb. boot and everything. Very worth it (97 CR250)

HORRIBLE!!!

DO NOT BUY!! My 2008 yz125 ran great with OEM and I should have left well enough alone. THEY DO LEAK!! All the reviews were CORRECT! Go with boyesen or stick with OEM. VFORCE are a waste of money and I could see light coming through the reeds right out of the box. DO NOT WASTE YOUR TIME!

Will I need to do anything to my 01 YZ 125 to accommodate the reeds, jet kit etc..?

If your bike is currently jetted properly you will likely not have to make any changes after installing this VForce 3 Reed Valve System. I would recommend installing the VForce and riding the bike to see how it is running then tuning your carburetor from there if necessary.
