High-Output Enduro Performance | OEM Ref: 31120-MEY-672
Keep your CRF450X trail-ready. Known for its dominance in Baja and endurance racing, the CRF450X demands an electrical system that can handle extreme heat and constant vibration. This Premium 12-Pole Magneto Stator is a precision-engineered replacement for OEM 31120-MEY-672, designed to provide a rock-solid spark and consistent charging—even in the most punishing off-road conditions.
Engineered for the Long Haul:
- Extreme Heat Resistance: Features high-grade copper windings insulated to withstand temperatures up to 200°C, preventing the common "hot-start" failures caused by OEM stator breakdown.
- 12-Pole High-Efficiency Design: Precision-wound to ensure stable AC voltage across the entire RPM range, supporting smooth idling and strong ignition.
- Enduro-Grade Protection: Built with superior lamination and sealed grommets to resist corrosion from moisture, mud, and hot engine oil.
- True Plug-and-Play: Includes the integrated pulsar (pickup) coil and factory-style connectors for a seamless, modification-free installation.

Fitment FAQ
Will this part fit my specific model and year?
This magneto stator is intended for Honda CRF450X (2005-2017). It is best matched to original part number(s) 31120-MEY-672, 2005-2017. Key physical/spec details from the product data include Inner Diameter: 32 mm, Outer Diameter: 77 mm, 32 mm. 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-MEY-672, 2005-2017 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 CRF450X/MEY-672 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-MEY-672, 2005-2017, treat the fitment as unconfirmed. Model years outside 2005–2017, 2005, 2017, 2006, 2007 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-MEY-672, 2005-2017. Recheck listed specs such as Inner Diameter: 32 mm, Outer Diameter: 77 mm, 32 mm. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
