Racing Lightweight Valve Spring Kit - KTM SX-F / XC-F 250 2013-2014

Product Information

KPMI® takes a scientific “System” approach when designing our Valve spring kits. Each component is designed to work with the others as part of the complete system. KPMI’s engineers use our proprietary design and simulation softwares, and draw on our 70+ years of design experience to create these systems. Our design, simulation, and manufacturing processes insure compatibility of the valve spring’s force and natural frequency with the cam profile, valvetrain mass, system harmonics, and the engine RPM. Our spring manufacturing partners are U.S based companies that are ISO certified. The Super-Clean Chrome Silicon valve spring wire we use is traceable back to Kobe Japan where some of the best spring wire in the world is manufactured. Combining our design and simulation protocols with this premium quality valve spring wire, and manufacturing processes including, heat treatment, stress relief, and shot peening, allow us to supply you with the best valve springs in the world.

Note: The use of KPMI® guides(#96-9642X and #96-9643X) may be necessary when using higher than stock lift cams.
