Race Tech Fork Spring 0.46 kg/mm, manufacturer part number FRSP 435146 and vendor part number 200-435146, is designed to provide accurate, consistent front suspension performance for select KTM off-road motorcycles. Choosing the correct spring rate is an important step toward improving handling, balance, and predictability, particularly for riders whose motorcycles are under-sprung for their weight or riding conditions.
This high-performance fork spring is made from chrome silicon wire for a high stiffness-to-mass ratio. Race Tech shot-peens and heat-treats each spring to improve durability and help maintain its specified rate during extended use. The 0.46 kg/mm spring rate helps support proper fork response and chassis balance when matched to the rider, motorcycle, and riding application.
Designed for fitment on select KTM models, this Race Tech spring fits 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-W. Verify the motorcycle model year, suspension specifications, and required spring rate before installation. Professional setup or installation is recommended to ensure correct suspension sag and performance.
Race Tech is known for producing accurately rated suspension springs for performance-oriented street and off-road applications. The FRSP 435146 fork spring is built to deliver dependable rate consistency without premature sagging or “sacking out,” making it a practical upgrade for riders seeking more controlled and predictable handling.
