2008–2009 Honda CBR1000RR Fireblade 18-Coil 5-Wire Stator 31120-MFL-641

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.
