Race Tech FRSP454748 Fork Spring kg/mm lb/in - 0.48 26.90

The Race Tech FRSP454748 is a high-performance replacement fork spring with a 0.48 kg/mm (26.90 lb/in) spring rate, designed to deliver precise, consistent suspension performance for dirt and street motorcycle applications. Selecting the correct spring rate is the single most important step toward achieving balanced, predictable handling — and Race Tech's extensive lineup ensures a proper match for a wide range of riders and riding styles.

Key Features:

• Spring Rate: 0.48 kg/mm (26.90 lb/in) — extremely accurate rates within 2% tolerance
• Material: Chrome silicon steel for an exceptional stiffness-to-mass ratio
• Shot-peened and heat-treated for long-term durability and fatigue resistance
• Preset (no sack-out) — maintains rate consistency over the life of the spring
• Lightweight construction reduces unsprung weight for improved suspension response
• Made in the USA
• Sold as a set (contains the quantity required per vehicle application)

Race Tech fork springs are an ideal first upgrade for any performance-minded rider. Stock bikes are typically under-sprung for the average rider's weight, leading to unbalanced and unpredictable handling. Upgrading to the correct spring rate improves ride quality, cornering accuracy, braking stability, and overall confidence on any terrain.
