The first step to great handling and predictability is selecting proper spring rates. 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.

Improve front-end balance, handling, and suspension predictability with the Race Tech Fork Spring 0.44 kg/mm, manufacturer part number FRSP 434644. Designed for riders who need a properly matched spring rate, this high-performance fork spring helps address the under-sprung condition commonly found on sport and off-road motorcycles. Correct spring selection supports consistent suspension response, improved rider control, and more predictable performance across changing terrain and riding conditions.
Manufactured by Race Tech from chrome silicon wire, the spring delivers a high stiffness-to-mass ratio while maintaining reliable performance under demanding use. The spring is shot-peened and heat-treated for durability, with accurate spring rates engineered to resist sagging or “sacking out” over time. Its 0.44 kg/mm rate is intended for compatible applications listed below and should be matched to the motorcycle, rider weight, riding style, and suspension setup.
This Race Tech fork spring fits the 2015 KTM 350 XC-F and 2015 KTM 350 SX-F; 2015 Husqvarna TE 300; 2014 and 2015 Husqvarna FE 250; 2014 and 2015 Husqvarna FE 501; 2014 Husqvarna TE 250; 2005 Kawasaki KX250F; and 2005 Kawasaki KX125. Verify motorcycle year, model, fork specifications, and required spring rate before installation. Professional installation and suspension setup are recommended for the best fit and performance.
Features:
- Spring Rate: 0.44 kg/mm for compatible motorcycle suspension applications
- Material: Chrome silicon wire for strength and reliable performance
- Construction: Shot-peened and heat-treated to improve durability
- Performance: High stiffness-to-mass ratio supports responsive suspension control
- Consistency: Accurate spring rate helps maintain predictable handling
