The Race Tech Fork Spring 0.56 kg/mm is designed to improve front-end support, handling balance, and ride predictability on compatible motocross motorcycles. This high-performance replacement spring helps address under-sprung factory suspension setups, providing a more controlled response for riders who require accurate spring rates and dependable performance.
Manufactured by Race Tech from chrome silicon wire, the FRSP 444956 fork spring delivers a high stiffness-to-mass ratio while maintaining durability under demanding riding conditions. The spring is shot-peened and heat treated to resist fatigue and prevent sacking-out, helping it retain its intended rate over time. Its precise 0.56 kg/mm rate supports consistent suspension behavior and allows suspension tuning to be matched more closely to rider weight, riding style, and terrain.
This Race Tech fork spring fits select 2014–2019 Yamaha YZ250F models, the 2019 Yamaha YZ450F, 2019–2021 Yamaha WR450F models, and the 2019 Suzuki RM-Z250.
