Yamaha YZ125 Fork Spring Kit - Eibach - EMS - '06-'21. A direct-fit Eibach spring kit for Yamaha YZ125 models from 2006 through 2021. This kit gives riders more precise spring rate options to better match fork feel to rider weight and riding style.

Built to Eibach standards for motorsport applications, the EMS fork springs replace the stock springs without requiring modification to fork internals. The matched left and right springs allow consistent compression and rebound behavior across both legs, helping you fine-tune front-end support, small-bump compliance and mid-stroke resistance. The kit is intended for riders and tuners who prefer to adjust mechanical spring rates before altering damping components.
