Specifically engineered for the Kawasaki KX250, this system is designed to provide immediate gains in throttle response and overall engine efficiency, helping you get the most out of every gear.

Frequently Asked Questions

Q: Will this reed valve improve my KX250's mid-range power?
A: Absolutely. The V-Force 3 is designed to smooth out the power delivery and improve air intake efficiency, which is most noticeable through the mid-range and throttle response.

Q: Is there any risk of the reed petals breaking?
A: Moto Tassinari uses high-grade carbon fiber materials designed to withstand the rigors of competitive motocross. While all reed petals are wear items, the V-Force 3 design is widely considered the most durable and reliable system on the market.

Expert Pro-Tip: When swapping your reed block, never use gasket sealer on the rubber-coated flange faces of the V-Force block. They are designed to seal perfectly against the cylinder and manifold on their own. Adding silicone or sealer here can actually create a gap or uneven surface that leads to air leaks—keep it clean and dry for the perfect seal.
