Race Tech Fork Spring 0.46 kg/mm for 2017-2019 Honda, Suzuki and Kawasaki Models – FRSP 454746

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.

Improve front-end balance, handling, and suspension predictability with the Race Tech Fork Spring 0.46 kg/mm, manufacturer part number FRSP 454746 and vendor part number 200-454746. Designed for high-performance motorcycle suspension applications, this fork spring helps provide a more suitable spring rate for riders whose motorcycles are under-sprung from the factory.

Race Tech manufactures this spring from premium chrome silicon wire for a high stiffness-to-mass ratio and consistent performance. Each spring is shot-peened and heat treated to improve durability, resist fatigue, and maintain its accurate rate during demanding riding conditions. The 0.46 kg/mm rate is engineered to support dependable fork performance and predictable chassis behavior when properly matched to rider weight, riding style, and suspension setup.

Fitment includes the 2017 Honda CRF450RX and CRF450R; 2018 Honda CRF450R; 2019 Honda CRF450R, CRF450RX, CRF250R, CRF450R W.E., and CRF250RX; the 2019 Suzuki RM-Z450; and the 2019 Kawasaki KX450F. Verify the motorcycle model, year, and required spring rate before installation. Professional installation and suspension setup are recommended to achieve the intended handling characteristics.
