Fitment FAQ
Will this part fit my specific model and year?
This magneto stator is intended for Engine Type; KTM; 390 Duke; 2013 – 2021; 373cc Single-Cylinder; RC 390. Listed year information includes 2013–2021, 2014–2021, 2013, 2021, 2014. It is best matched to original part number(s) 90230040000, 2013-2021, 2014-2021, 93730040000. Key physical/spec details from the product data include 373cc. 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 90230040000, 2013-2021, 2014-2021, 93730040000 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 KTM 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 90230040000, 2013-2021, 2014-2021, 93730040000, treat the fitment as unconfirmed. Model years outside 2013–2021, 2014–2021, 2013, 2021, 2014 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): 90230040000, 2013-2021, 2014-2021, 93730040000. Recheck listed specs such as 373cc. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
