Race Tech 0.48 kg/mm Fork Spring FRSP 454748 is designed to help improve front-suspension balance, handling, and predictability on compatible off-road motorcycles. Selecting the correct fork spring rate is essential for achieving controlled suspension performance, especially when the original spring is too soft for the rider or riding conditions. This Race Tech spring is manufactured for accurate, consistent performance and is an excellent choice for riders tuning their motorcycle for improved control.
Made from high-quality chrome silicon wire, the spring provides a high stiffness-to-mass ratio while maintaining dependable durability. It is shot-peened and heat treated to resist fatigue and maintain its specified rate during repeated use. The Race Tech 0.48 kg/mm spring is engineered to prevent spring rate degradation, helping deliver consistent suspension response over time. Its precise rate supports more balanced chassis behavior and improved confidence during braking, cornering, and aggressive riding.
This fork spring fits select 2017–2019 Honda, 2019 Suzuki, and 2019 Kawasaki motorcycles, including the Honda CRF450R, CRF450RX, CRF250R, CRF450R W.E., and CRF250RX; Suzuki RM-Z450; and Kawasaki KX450F.
