VFORCE offers you this double roof valve box for your motocross KAWASAKI KX 250cc. MOTO TASINARI has developed this type of valve to offer more torque and especially a better controlled flow to facilitate the driving and get the most performance possible to your motocross. This valve gear model is called V FORCE 3. With its double roof architecture it allows to open the slats 2 times less than the original ones. To be clear, an engine running at 8000 rpm, the slats open and close 133 times! With an original slat the movement is longer and so is the motor reaction. With this W-system, the 4 blades move 2 times less distance while feeding your engine perfectly. The engine reacts much better at any rpm and gives much more torque. The blades are made of carbon to offer a good rigidity and reliability. The thickness is specially studied for each engine to offer the most performance possible. The air flow has also been reworked to have the most flow and the best direction possible. You will have this valve gear and the best of the admission for 2-stroke engine
