Product Overview
Replace a weak, burned, or failed stator with this 18-coil 3-wire magneto stator, designed for the 1985 Suzuki GSX1100EF and compatible GSX1100 charging system applications using reference number 31401-00A00.
The stator is an important 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 Suzuki GSX1100EF has weak charging, low battery voltage, dim lights, repeated battery drain, or stator-related 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 layout, mounting hole distance, and dimensions before ordering.

Fitment FAQ
Will this part fit my specific model and year?
This stator is designed for the 1985 Suzuki GSX1100EF and related Suzuki GSX1100 charging system applications using matching reference numbers and dimensions. Please compare your original stator’s wire count, connector layout, inner diameter, outer diameter, mounting hole distance, thickness, 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 is commonly associated with 31401-00A00 and 31401-08A00. However, OEM number alone is not enough. Please also confirm the 18-coil 3-wire layout, plug style, inner diameter, outer diameter, mounting hole distance, and stator thickness.
What models or situations does this part not fit?
This part does not fit Suzuki GSX1100, GSX750, GS1150, or other Suzuki models that use a different stator diameter, different wire count, different connector layout, different mounting hole spacing, or a different charging system design. It is also not a replacement for the regulator rectifier, battery, ignition coil, starter motor, rotor, or complete wiring harness.
What should I check before ordering?
Before ordering, please check your motorcycle’s make, model, year, OEM/reference number, original stator coil count, wire count, connector shape, inner diameter, outer diameter, mounting hole distance, stator thickness, and overall shape. For best fitment, compare the product photos and specifications with your original stator before purchase.
