Restore 12V Reliability | OEM Ref: 31120-459-921
Keep your "Postie" delivering performance. The Honda CT110 is legendary for its reliability, but an aging stator can lead to weak sparks and battery drain. This premium 12V Magneto Stator is a direct plug-and-play replacement designed specifically for the 1991–2013 models, ensuring your bike starts first kick and your lights stay bright.
Why This Stator is a Postie Essential:
- Steady 12V Output: Engineered to eliminate voltage fluctuations, protecting your battery and ensuring a consistent charge even at low idle.
- Superior Heat Management: High-quality copper windings are treated with a thermal-resistant coating to prevent internal shorts—a common cause of failure in high-mileage CT110 engines.
- Instant Start Performance: Delivers a high-intensity signal to the ignition system to cure "hard-starting" and weak spark issues.
- No-Fuss Installation: A true bolt-on unit that matches factory mounting points and OEM connectors perfectly.

Fitment FAQ
Will this part fit my specific model and year?
This magneto stator is intended for Honda CT110 Postie Bike (1991-2013). It is best matched to original part number(s) 31120-459-921, 1991-2013, POST-1991, PRE-1991. Key physical/spec details from the product data include Steady 12V Output: Engineered to eliminate voltage fluctuations, protecting your battery and ensuring a consistent charge even at low idle., Voltage System: 12V Models (Post-1991), Outer Diameter: 88mm (3.46"). 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 31120-459-921, 1991-2013, POST-1991, PRE-1991 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 CT110 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 31120-459-921, 1991-2013, POST-1991, PRE-1991, treat the fitment as unconfirmed. Model years outside 1991–2013, 1991, 2013 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): 31120-459-921, 1991-2013, POST-1991, PRE-1991. Recheck listed specs such as Steady 12V Output: Engineered to eliminate voltage fluctuations, protecting your battery and ensuring a consistent charge even at low idle., Voltage System: 12V Models (Post-1991), Outer Diameter: 88mm (3.46"). If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
Construction of the stator coil is solid, exactly what you'd want in a replacement part. Nothing feels loose or anything, and it appears to be of excellent craftsmanship. Removal of the stator cover and old part and install of the new coil was quick and simple, and it functions just like it's brand new one I reattached the cover and cover gasket. The cable is basically plug and play, and the grommet is exactly where it I needed it to be to seat it when attaching it and the retainer clip to the cover. Definitely a great product I would recommend to anyone looking for a replacement.
