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.

Fitment FAQ
Will this part fit my specific model and year?
This stator is designed for select Yamaha YZ four-stroke dirt bikes, including YZ400F 1998–1999, YZ426F 2000–2002, YZ250F 2001–2005, and YZ450F 2003–2005. Please compare your original stator’s OEM/reference number, wire count, connector layout, outer diameter, inner diameter, iron core height, and overall shape before ordering.
Do I need to match the OEM part number?
Yes, matching the OEM or reference number is strongly recommended. This stator commonly replaces 5SF-85560-00, 5XD-85560-00, 5XD-85560-09, 5BE-85560-00, and related 5BE-85560 replacement numbers. However, OEM number alone is not enough. Please also confirm the 4-coil 6-wire layout, plug style, outer diameter, inner diameter, and original stator shape.
What models or situations does this part not fit?
This part does not fit Yamaha YZ models that use a different stator diameter, different wire count, different connector layout, different OEM number, or different ignition system design. Do not use it for YZ250F 1998–2000, because those years are not a valid YZ250F fitment range. It is also not a replacement for the CDI, ignition coil, spark plug, regulator rectifier, flywheel, or complete wiring harness.
What should I check before ordering?
Before ordering, please check your dirt bike’s make, model, year, OEM/reference number, original stator coil count, wire count, connector shape, outer diameter, inner diameter, iron core height, pickup coil layout if applicable, and overall shape. For best fitment, compare the product photos and specifications with your original stator before purchase.
