The all-new VFORCE4X for select GasGas, Husqvarna and KTM TBI fuel injected 125/150/250 and 300cc motorcycles has been designed to offer you exceptional durability and overcome the shortcomings of the stock reed valve system.

 

VForce4R offers enhanced reed petal life as well as all the added benefits of the unique VForce reed valve design. Vforce 4 reed valves are the world leading design and performance reed valve with gains in power no other reed valve standard or aftermarket can match. With a twin stack system you get twice the tip surface and with petals only needing to travel half the distance of a normal single stack, Vforce4 air/fuel control is massively improved when compared to stock.
