The production steps (cold winding, tempering, shot peening, end grinding, and polishing) are aimed at ensuring geometry and surface conforming to specifications, and allow for precise identification of the spring rate through laser engraving. These springs are intended for modifications and replacements on off-road machines where compatible components with enduro/motocross constraints are sought.

Examples of models for which these springs are commonly chosen: YAMAHA YZ 450 F (2026), BETA RX 450 4T (2026), SUZUKI RM-Z 250 (2026). Check compatibility with your fork before installation.
