Description

Upgrade your Kawasaki KX450F with the PROX Exhaust Valve Conversion Set, part number 28.SES4409-1. Specifically designed for models from 2009 through 2018, this comprehensive kit offers a reliable and cost-effective solution to enhance engine durability and performance. Featuring high-quality steel valves and specially engineered stronger valve springs, this set is an excellent alternative to OEM titanium valves, providing increased wear resistance and longevity under demanding riding conditions.

The steel valves included are nitrided to achieve high microhardness, which significantly reduces wear and extends service life. The nitriding process also results in a supersmooth surface finish, minimizing friction between the valve stem and guide, thereby improving overall engine efficiency. The accompanying high-performance chrome vanadium steel springs are meticulously crafted to handle the additional weight of the steel valves and maintain optimal tension at high RPMs. This ensures consistent valve operation and engine responsiveness.

Designed for straightforward installation, the PROX Exhaust Valve Conversion Set utilizes OEM retainers, bases, and seals, allowing for easy replacement without requiring further engine modifications. This fully rebuildable kit is ideal for riders seeking durable, high-quality components that deliver both performance and reliability. Whether you're performing routine maintenance or preparing for a competitive event, this complete package simplifies the replacement process and ensures your Kawasaki KX450F continues to perform at its best.

Built with precision and attention to detail, the PROX Exhaust Valve & Spring Kit is the perfect upgrade for enthusiasts demanding longevity and consistent engine performance. Trust PROX*s expertise to keep your motorcycle running smoothly mile after mile, race after race.
