Race Tech 0.52 kg/mm Fork Spring FRSP 454752 for Honda, Suzuki and Kawasaki Motorcycles

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.

Upgrade front-end performance with the Race Tech 0.52 kg/mm Fork Spring, manufacturer part number FRSP 454752 and vendor part number 200-454752. Designed for riders who need accurate spring rates and improved suspension balance, this high-performance fork spring helps provide more predictable handling than an under-sprung setup. The spring is engineered for motorcycle applications where proper rate selection is essential to maintaining control, stability, and consistent fork response.

Race Tech manufactures this spring from chrome silicon wire for a high stiffness-to-mass ratio and dependable performance. Each spring is shot-peened and heat-treated to improve durability and resist sacking-out over time. Its precise 0.52 kg/mm rate supports consistent suspension behavior and makes it a practical choice for tuning the front suspension to rider weight, riding style, and terrain. Professional installation and setup are recommended to confirm the correct spring rate and suspension adjustment for your application.
