Improve front-end balance, handling, and ride predictability with the Race Tech Fork Spring 0.52 kg/mm. Designed for performance-focused riders, this high-quality fork spring helps provide the proper spring rate for motocross and off-road applications. The spring is manufactured from chrome silicon wire to deliver a high stiffness-to-mass ratio, supporting consistent suspension performance under demanding riding conditions.
The Race Tech FRSP 444952 is shot-peened and heat-treated for durability, accurate spring rates, and reliable resistance to sagging or “sacking out” over time. Selecting the correct fork spring rate can help address an under-sprung setup, improve chassis balance, and create a more controlled, predictable feel during braking, cornering, and uneven terrain. This model is designed as a direct-fit suspension component for compatible applications and is suitable for riders seeking a precise suspension upgrade.
Fitment includes the 2019, 2014, 2015, 2016, and 2017 Yamaha YZ250F; 2019 Yamaha YZ450F; 2019, 2020, and 2021 Yamaha WR450F; and the 2019 Suzuki RM-Z250.
