Suzuki GS250 GS400 GS450 GS500 GS550 GS750 Magneto Stator 1977-2000

Product Overview

Restore reliable charging and ignition performance with this motorcycle magneto stator coil, designed for selected Suzuki GS250, GS300, GS400, GS425, GS450, GS500, GS550, GS650, and GS750 motorcycle applications.

Built to replace common Suzuki GS-series stator references including 31401-45020 / 31401-45030 / 31401-45021, this stator helps solve common electrical issues such as battery not charging, weak or no spark, hard starting, unstable voltage, and intermittent charging failure.

Made with high-quality materials, this stator is designed for high temperature resistance, chemical corrosion resistance, waterproof performance, stable electrical output, and long service life. It is a practical replacement for a worn, burned, or failing original stator on correctly matched Suzuki GS models.
