1985–2005 Kawasaki KLX250 KLR250 KL250 12-Coil 4-Wire Stator 21003-1121

Product Overview

Replace a weak, burned, or failed stator with this 12-coil 4-wire magneto stator, designed for select Kawasaki KLX250, KLR250, and KL250 motorcycles from 1985–2005.

The stator is an important part of the motorcycle charging and ignition system. It helps generate electrical power while the engine is running, supporting the battery, lights, ignition system, and other electrical components. If your Kawasaki KLX250, KLR250, or KL250 has weak charging, no spark, dim lights, unstable voltage, or stator-related electrical failure, replacing the stator may help restore normal electrical performance.

Built with a metal lamination core and copper windings, this replacement stator is designed for stable conductivity, heat resistance, and long service life. Please compare your original stator’s OEM number, wire count, plug layout, mounting hole distance, and dimensions before ordering.
