Fitment Note
Please confirm your vehicle model, year, stator dimensions, wire count, connector style, and original stator appearance before ordering.
This listing is intended for selected Honda CB400 Super Four / CB400SF NC31 1992–1998 applications. Compatibility may vary by market version and wiring setup, so matching by 107 mm outer diameter + 42 mm inner diameter + 18 coil + 5-wire layout + connector style is strongly recommended before purchase.
If you are unsure about compatibility, contact us with your model, year, connector photos, and original stator measurements before purchase.
Installation Note
Professional installation is recommended.
Before installation, inspect related components such as the battery, regulator/rectifier, wiring harness, connectors, flywheel, and charging system to avoid repeat failure caused by another faulty part.
Burned connectors, a weak battery, or a faulty regulator/rectifier may cause repeated stator failure, so the full charging system should be checked before installing the new stator.

Fitment FAQ
Will this part fit my specific model and year?
This magneto stator is intended for Engine / HP / CC. Listed year information includes 1992–1998, 1992, 1998. It is best matched to original part number(s) 31120-MV9-671, 31120-MBZ-611. Key physical/spec details from the product data include Outer Diameter: 107 mm, Inner Diameter: 42 mm, 400cc. 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-MV9-671, 31120-MBZ-611 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 CB400/NC31 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-MV9-671, 31120-MBZ-611, treat the fitment as unconfirmed. Model years outside 1992–1998, 1992, 1998 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-MV9-671, 31120-MBZ-611. Recheck listed specs such as Outer Diameter: 107 mm, Inner Diameter: 42 mm, 400cc. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
