This magnesium power valve cover is a direct replacement outer cover for Kawasaki KX125 models from 1994 to 2002, designed to replicate the factory-style magnesium covers used on race and works bikes of the era.

Manufactured from lightweight magnesium, this cover replaces the original OEM power valve cover and encloses the power valve cavity without altering valve timing, actuation, or internal components. It is intended for restorations, race builds, and period-correct KX125 projects where authenticity and reduced weight matter.

This is an external engine cover only. It does not modify, upgrade, or interact with the internal power valve mechanism in any way.
