Reed Valve V-Force 3 KTM 200 / 250

V-FORCE 3 valve

The V-Force reed valve stands out as a groundbreaking advancement in the world of two-stroke engines. Initially designed for motocross, it subsequently gained prominence across diverse disciplines and for a variety of vehicle models.

ADVANTAGES VFORCE 3 reed valve

The VForce 3 from Moto Tassinari features a unique architecture with a V-shape in the middle. This special design allows for using twice as many reeds (4 instead of 2), resulting in improved cylinder filling. This in turn improves throttle response and performance at low RPMs.

In 2-stroke tuning, a reed valve upgrade is often one of the most effective ways of optimizing engine performance and achieving a power boost across the entire RPM range.

There is now an upgraded version the V-Force 3, known as the V-Force 4, which we also carry in our shop.

Reed valves for scooter, motorcycle and moped

The reed valve is an integral part of the intake system. It usually sits under the intake manifold.

How does a reed valve work?

The reed valve is usually V-shaped and is equpped with two blades. When the reed valve is opened, mixture will flow; when the reed valve is closed, the flow is significantly reduced. The flow is controlled by the opening of the carburetor slide, which controls the amount of mixture and affects RPM.

What kind of reed valve?

The type and shape of the reed valve can affect engine performance. Common types include the V-Force reed valve in a W-shape with 4 reed petals, and oversize versions with more volume than the original reed valves.

Adjusting the reed valve

You can improve engine output by using petals in different thicknesses, or by using a stuffer or a reed valve spacer. You can influence the mixture flow, which can affect the overall performance of the engine.

Note: When installing also change the intake gasket!
