2004–2015 Yamaha MT-03 XT660R XT660X XT660Z 18-Coil 9-Wire Stator 5VK-81410-00

Product Overview

Replace a weak, burned, or failed stator with this 18-coil 9-wire magneto stator, designed for select Yamaha MT-03 660, XT660R, XT660X, and XT660Z Ténéré motorcycles using OEM reference number 5VK-81410-00.

The stator is an important part of the motorcycle charging and ignition system. It helps generate electrical power while the engine is running, supporting the battery, ignition system, lights, sensors, and other electrical components. If your Yamaha MT-03 660 or XT660 has weak charging, low battery voltage, dim lights, repeated battery drain, hard starting, unstable electrical output, or stator-related failure, replacing the stator may help restore normal electrical performance.

Built with a metal lamination core and copper windings, this replacement stator is designed for stable conductivity, heat resistance, corrosion resistance, and long service life. Please compare your original stator’s OEM number, coil count, wire count, connector layout, pickup / trigger coil position, mounting hole distance, thickness, and dimensions before ordering.
