1998–2005 Yamaha YZ250F YZ400F YZ426F YZ450F 4-Coil 6-Wire Stator

Product Overview

Replace a weak, damaged, or failed stator with this 4-coil 6-wire magneto stator, designed for select Yamaha YZ four-stroke dirt bikes including YZ400F, YZ426F, YZ250F, and YZ450F applications.

The stator is an important part of the motorcycle ignition and electrical system. It helps generate electrical output while the engine is running, supporting ignition performance and related electrical components. If your Yamaha YZ has no spark, weak spark, hard starting, intermittent ignition loss, poor running, or stator-related electrical failure, replacing the stator may help restore normal performance.

Built with high-quality copper wire and insulation, this replacement stator is designed to deliver stable electrical output, withstand off-road vibration, and handle high-temperature riding conditions. Please compare your original stator’s OEM number, wire count, connector layout, mounting style, and dimensions before ordering.
