Product Overview
Restore reliable electrical performance to your Kawasaki KLX dirt bike with this replacement magneto stator coil, designed for KLX125S, KLX140, and KLX150 series models.
Built to replace Kawasaki OEM stator numbers 21003-0116 and 21003-0066, this stator helps provide stable electrical output for ignition and charging system performance. It is a practical replacement for common electrical issues such as weak spark, hard starting, no-start problems, unstable output, or stator failure after long off-road use.
Constructed with quality copper windings and heat-resistant insulation, this stator is made to handle the vibration, heat, dust, and trail conditions commonly found in off-road riding.

Fitment FAQ
Will this part fit my specific model and year?
This magneto stator is intended for OEM Reference; Kawasaki; KLX140; Standard / A / S models; 2008–2024; 21003-0116, 21003-0066. It is best matched to original part number(s) 21003-0116, 21003-0066. Key physical/spec details from the product data include Full-size wheel model: 2017–2024, Outer Diameter: 107 mm / 4.21 in, Inner Diameter: 38 mm / 1.50 in. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. Match your original part number to 21003-0116, 21003-0066 before purchase. For this magneto stator, also compare the OEM number, outer/inner diameter, core height or thickness, plug shape, wire count, mounting holes, pickup position, and rubber grommet style. This is especially important for Kawasaki KLX125S/KLX140/KLX150 models because similar model names can use different parts by year or trim.
What models or situations does this part not fit?
Do not order this magneto stator for machines outside the listed compatibility, or for units with different plug layouts, pickup-coil positions, wire counts, stator diameters, or charging/ignition configurations. If your original part number does not cross-reference with 21003-0116, 21003-0066, treat the fitment as unconfirmed. Model years outside 2008–2024, 2017–2024, 2008–2019, 2009–2024, 2008 should be verified separately. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the OEM number, outer/inner diameter, core height or thickness, plug shape, wire count, mounting holes, pickup position, and rubber grommet style. Confirm OEM/cross-reference number(s): 21003-0116, 21003-0066. Recheck listed specs such as Full-size wheel model: 2017–2024, Outer Diameter: 107 mm / 4.21 in, Inner Diameter: 38 mm / 1.50 in. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
The coil is well made and easy to install and got me going again fast. This coil is exactly as described, arrived quickly, and was well-packaged. The seller communicated clearly and made sure I was fully satisfied with my purchase. I highly recommend this seller to anyone looking for a smooth and trustworthy transaction. This works by capturing a changing magnetic field, inducing voltage to generate power, in the case of ignition coils, creating high-voltage sparks. It is very well balanced, quick and easy to replace and install and has NO Issues at all while running. It generates the required electricity and will last a very long time. It is also very fairly priced. This generator coil is a crucial component, made of top grade precision enamel-coated copper wire, wrapped around the solid magneto that converts mechanical energy into electricity through electro magnetic induction. I had a fantastic experience purchasing from this seller.
Just right for a KLX140 repair. Fits, works. Clip is tight
This was exactly what was needed to fix our bike and get it up and running again. Not much I can say other than it worked out well (had someone else do the work for me since I am not a cycle mechanic). But the actual mechanic tells me that it is a good quality replacement part and was installed with no issue.
