Reed Valve System Vforce 4 Vforce Husqvarna Tc 250 2014-2016 Moto Tassinari

Vforce 3 Vforce lamellar pack
The V-Force 3 has features that are not found in any other reed valve on the market. Like the double contact surface, the adjustable blade stops, the fluxed surface of the lamella cage. Doubling the contact surface of the lamella end is sufficient to open the lamella 50% of the original to obtain an equal flow. A decisive advantage, considering that a lamella opens and closes 133 times per second at 8000 rpm. The lamella works half of what works an original lamella, with great reduction of wear and longer life of the component.

In addition, a significant improvement in supply over the entire curve is obtained, with a significant boost to medium and low revs. An instantaneous response of the engine to the gas command is just the beginning of the list of improvements.

The petals of the slats now rest on a radiused surface, which creates an "loading" effect that improves an already lightning acceleration. The new design of the slat cage allows the slat to be "embedded" in the cage itself, with a damping effect on the end of the slat and preventing any kind of reflux in the suction duct.
Each V-Force valve is equipped with an adjustable reed stop that allows you to change the lamella tension from high to low in a short time. This feature allows you to fine tune the delivery and the result is sensitive. A low tension helps the torque and the pull at low revs, while a high tension improves the power of the tip.

What's new about V-Force 3?

Symmetrical lamella petals:
VForce3 now uses symmetrical lamella petals. This eliminates the differentiation between internal and external lamellas.
Speed ​​change of slats:
VForce3 is the first flap valve with a patented slat-mounting slat fixing system. No more screws, just a moment to change the slats.
Specific fluxing for each model
Advanced composite materials for the construction of lamellae:
New construction system in carbon fiber and resin, specific for the new design of the VForce3
Lamellas of new design:
Eliminates the need for fixing screws and reduces the possibility of breakage.
Wing profile applied to the slats
It increases the speed of the mixture flow, with an optimal pulverization.
