With over 500 Hi-Performance Springs to choose from, Race Tech is almost guaranteed to have the spring you need. Sportbikes are generally under-sprung for the average rider, causing the bike to be unbalanced and unpredictable.\n\u003cp\u003eImprove front-end control and handling consistency with the Race Tech Fork Spring 0.42 kg\/mm, manufacturer part number FRSP 435142 and vendor part number 200-435142. Designed for riders who need a properly matched suspension rate, this high-performance fork spring helps create a more balanced and predictable motorcycle. It is a suitable upgrade for sport and off-road applications where the original spring rate may be too soft for the rider, terrain, or riding style.\u003c\/p\u003e\u003cp\u003eManufactured by Race Tech, the spring is made from chrome silicon wire for a high stiffness-to-mass ratio and dependable performance. It is shot-peened and heat treated to support long-term durability, accurate spring rates, and resistance to sagging or “sacking out” under repeated use. Proper spring selection is an important foundation for suspension tuning, and the 0.42 kg\/mm rate provides a targeted option for riders seeking improved fork support without unnecessary weight.\u003c\/p\u003e\u003cp\u003eThis Race Tech fork spring fits select KTM models, including the 2013 and 2014 KTM 500 XCF-W; 2005 KTM 250 SX; 2006 KTM 250 SX, 250 SX-F, and 250 XC; and 2007 through 2009 KTM 250 XC and 250 XC-W models as specified by the application list. Verify the motorcycle model year and suspension specifications before installation. Professional installation and suspension setup are recommended to ensure proper fitment, preload, and performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e0.42 kg\/mm fork spring rate for targeted suspension
