Yamaha YZ125 Fork Spring Kit - Eibach - EMS - `06-`21. This Eibach EMS fork spring kit is made for Yamaha YZ125 models from 2006 through 2021 and provides a direct-fit option for riders looking to refine fork feel. It’s a straightforward upgrade intended for riders who want more control over fork response.

The kit uses Eibach EMS springs engineered for consistent manufacturing tolerances and reliable fitment with the YZ125 fork assemblies. By changing the spring characteristics you can better match fork behavior to rider weight, riding style, and track conditions without altering internal damping components. The kit is useful for riders who prefer to dial in preload and spring rate separately from cartridge or damper adjustments.
