Fitment FAQ
Will this part fit my specific model and year?

It is best matched to original part number(s) 31120-HM3-671, 1993-2009, 11395-HM3-670. Key physical/spec details from the product data include Outer Diameter: 92mm (3.62"), Inner Diameter: 35mm (1.38"), Iron Core Height: 16mm (0.63"). 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 31120-HM3-671, 1993-2009, 11395-HM3-670 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 Honda TRX300X 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 31120-HM3-671, 1993-2009, 11395-HM3-670, treat the fitment as unconfirmed. Model years outside 1993–2009, 1993–2008, 1993–2000, 1993, 2009 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): 31120-HM3-671, 1993-2009, 11395-HM3-670. Recheck listed specs such as Outer Diameter: 92mm (3.62"), Inner Diameter: 35mm (1.38"), Iron Core Height: 16mm (0.63"). If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
