The Race Tech Fork Spring 0.52 kg/mm, part number FRSP 435152 and vendor part number 200-435152, is designed to help improve front-end balance, handling, and suspension predictability on compatible KTM motorcycles. Selecting the correct spring rate is an important step in tuning a motorcycle for rider weight, riding style, and terrain. This spring is especially suited to riders who need more appropriate fork support than the original equipment setup provides.
Manufactured by Race Tech, this high-performance fork spring is made from chrome silicon wire for a high stiffness-to-mass ratio and consistent performance. The spring is shot-peened and heat-treated to promote durability, accurate spring rates, and resistance to sagging or “sacking out” during extended use. Its 0.52 kg/mm rate provides a reliable foundation for suspension tuning and can contribute to more controlled braking, cornering, and rough-terrain performance when properly matched to the motorcycle and rider.
Fitment includes the 2013 and 2014 KTM 500 XCF-W; 2005 KTM 250 SX; 2006 KTM 250 SX, 250 SX-F, and 250 XC; 2007 KTM 250 XC and 250 XC-W; and 2008 and 2009 KTM 250 XC-W. Confirm motorcycle model year and suspension specifications before installation. Professional installation and suspension setup are recommended to ensure the Race Tech FRSP 435152 spring is correctly installed and tuned for the application.
