The K-Tech Front Fork Spring 9.0N is a high-precision linear spring developed for elite-level motorcycle racing.
These springs are the go-to choice for tuners and racers using K-Tech DDS (Direct Damping System) and 20IDS fork cartridges. The 9.0N rate offers a versatile "middle-ground" setup, providing excellent front-end support without sacrificing the compliance needed to maintain grip over surface imperfections.
Every spring is manufactured to DIN 2095 Grade 1 standards from premium Chrome Silicone wire.
Through a rigorous multi-stage process of cold coiling, heat treatment, and shot peening, K-Tech ensures the rate remains stable and consistent under the extreme thermal and mechanical stresses of racing.
