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.
…if you are serious about
performance, both on the lake and on the track, the VForce reed valve
system is your best chance to obtain the ultimate in competitive power.

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 are
they receive less wear than the reed petals on a conventional reed
valve design.
One of the best things consumers
can do for the money is replace the stock reed cage with a set of Moto
Tassinari VForce reed valves.

While two-strokes may have lost their place in the pro ranks of AMA
supercross and motocross racing, they are still alive and well, and
even prospering in some disciplines such as off-road racing. Currently
the two-stroke motorcycle appears to be making a bit of a resurgence in
popularity in the UK and other parts of Europe. Because of both the
superior performance and durability of the VForce reed valve system you
will find the VForce as an OEM item in select KTM, Husqvarna, TM, BETA,
Gas Gas, and Cobra motorcycles. These manufactures realize both the
performance and durability benefits of the VForce3 and chose to spec
their motorcycles with the finest reed valve system available.
I have been doing this for a long
time—for an aftermarket company to make a product that outperforms what
the factory’s make is pretty rare these days. VForce is one of those
rare exceptions.
—Roger DeCoster, Manager KTM MX/SX Team
The VForce3 reed valve system has always enjoyed a strong following
in the snowmobile market, which really isn't too surprising as the
first VForce reed valves ever manufactured were exclusively for
snowmobiles. We soon branched out into motorcycles, quads, personal
watercraft, micro sprints and more. We continued to dominate the
snpwmobile aftermarket market with the VForce reed valve system racking
up championships in oval, ice drags, grass drags, pavement drags,
hillcross, hilclimbs, snocross and more. The VForce reed valve system
can now be found OEM in the race sleds of Arctic Cat, Polaris and
Ski-Doo.
The VForce3 Reed Valve System is
the perfect combination of performance and durability, making it a
natural choice for the sleds Team Arctic races.
—Russ Ebert, Race Manager for Team Arctic Cat
Though there is currently a lot of fuss being made over four-stroke
technology, Moto Tassinari continues to refine and add technology to
our VForce product line. We have just completely redesigned our VForce
reed valve system for the KTM 250/300 motorcycle line. This is the
exact same reed valve that will be used as OEM by KTM for the 2012
model year. It is available for consumer purchase now.
The VForce3 reed valve system
improved the boost in the upper midrange and wants to let the bike rev
to the moon.

VForce3 Product Information
Though the original VForce3 reed valve system has been out for over ten
years it's still "new" technology to some, as well as constantly
undergoing refinements in design. We'll do our best to answer some of
the most common questions below.
01WHAT

CAN I EXPECT AFTER INSTALLING THE VFORCE3 REED VALVE SYSTEM?
Dyno testing shows an immediate horsepower gain of anywhere from 5-10%
through the majority of the powerband. The VForce3 also greatly
increases throttle response and acceleration, while also broadening the
peak power.
04WHAT'S
INVOLVED WITH INSTALLING THE VFORCE3 REED VALVE SYSTEM?
Simply remove the stock reed cage assembly and replace with the VForce3
