Product Overview
Replace a weak, burned, or failed stator with this 18-coil 5-wire magneto stator, designed for 2008–2009 Honda CBR1000RR Fireblade motorcycles using OEM reference number 31120-MFL-641.
The stator is a key part of the motorcycle charging system. It helps generate electrical power while the engine is running, supporting the battery, lights, ignition system, and other electrical components. If your Honda CBR1000RR has battery charging problems, dim lights, unstable voltage, or repeated electrical failure, replacing the stator may help restore normal charging performance.
Built with a metal lamination core and copper windings, this replacement stator is designed for stable conductivity, heat resistance, and long service life. Please compare your original stator’s OEM number, wire count, connector style, trigger coil position, mounting hole distance, and dimensions before ordering.

Fitment FAQ
Will this part fit my specific model and year?
This stator is designed for 2008–2009 Honda CBR1000RR Fireblade models, including CBR1000RR8 and CBR1000RR9, using OEM reference number 31120-MFL-641. Please compare your original stator’s OEM number, wire count, plug layout, trigger coil position, inner diameter, outer diameter, and mounting hole distance before ordering.
Do I need to match the OEM part number?
Yes, matching the OEM part number is strongly recommended. This stator replaces OEM 31120-MFL-641. However, OEM number alone is not enough. Please also confirm that your original stator uses the same 18-coil 5-wire design, connector style, mounting hole spacing, trigger mounting position, and overall dimensions.
What models or situations does this part not fit?
This part does not fit Honda CBR1000RR models outside the 2008–2009 fitment range if they use a different stator design, OEM number, wire count, connector layout, trigger position, or mounting hole spacing. It is also not suitable if your charging issue is caused only by a bad regulator rectifier, weak battery, damaged wiring, burned connector, or poor ground connection.
What should I check before ordering?
Before ordering, please check your motorcycle’s make, model, year, OEM part number, original stator coil count, wire count, connector shape, inner diameter, outer diameter, mounting hole distance, trigger mounting hole distance, trigger mounting hole diameter, and stator thickness. For best fitment, compare the product photos and specifications with your original stator before purchase.
