Product Overview
Replace a weak, burned, or failed stator with this 18-coil 5-wire magneto stator, designed for select Kawasaki EX500, EX400, GPZ500, GPZ400S, ER500 / ER-5, EN400, EN500, Vulcan 400, Vulcan 500, Vulcan 500 LTD, KLE400, KLE500, and 454 LTD motorcycle applications using OEM reference number 21003-1123.
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, ignition system, lights, and related electrical components. If your Kawasaki motorcycle has weak charging, repeated battery drain, dim lights, hard starting, unstable electrical output, or stator-related 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, corrosion resistance, and long service life. Please compare your original stator’s OEM number, coil count, wire count, connector layout, pickup / trigger coil position, mounting hole distance, thickness, and dimensions before ordering.

Fitment FAQ
Will this part fit my specific model and year?
This stator is designed for select Kawasaki EX500, KLE500, KLE400, ER500 / ER-5, EN500, EN400, Vulcan 400, Vulcan 500, Vulcan 500 LTD, GPZ500, GPZ400S, and 454 LTD applications using OEM reference number 21003-1123. Because these Kawasaki models cover multiple markets and year ranges, please compare your original stator’s OEM number, wire count, connector layout, inner diameter, outer diameter, mounting hole distance, trigger coil position, thickness, and overall shape before ordering.
Do I need to match the OEM part number?
Yes, matching the OEM or reference number is strongly recommended. This stator replaces Kawasaki OEM 21003-1123 and may cross-reference with 21003-1267 on some listings. However, OEM number alone is not enough. Please also confirm the 18-coil layout, supplied 5-wire configuration, DC electrical type, plug style, inner diameter, outer diameter, mounting hole distance, trigger mounting position, trigger hole diameter, and stator thickness.
What models or situations does this part not fit?
This part does not fit Kawasaki EX500, KLE500, ER500, EN500, Vulcan, GPZ, Ninja, or other Kawasaki models that use a different stator diameter, different wire count, different connector layout, different pickup / trigger coil position, or different charging system design. It is also not a replacement for the regulator rectifier, battery, CDI, ignition coil, flywheel, starter motor, or complete wiring harness.
What should I check before ordering?
Before ordering, please check your motorcycle’s make, model, year, trim version, OEM/reference number, original stator coil count, wire count, connector shape, inner diameter, outer diameter, mounting hole distance, trigger mounting hole distance, trigger mounting hole diameter, stator thickness, and overall shape. For best fitment, compare the product photos and specifications with your original stator before purchase.
