ARASHI | BMW S1000RR 2009-18 STATOR MAGNET COIL

Arashi High-Performance Stator Magnet Coil — BMW S1000RR / S1000R / S1000XR (2009–2018)

Keep your motorcycle's electrical system performing at its peak with the Arashi Stator Magnet Coil, engineered specifically as a direct replacement for BMW's high-revving 999cc inline-four platform. Built with high-purity copper windings and heat-resistant insulation, this generator coil delivers consistent voltage output to support your ignition, lighting, quickshifter, complex ABS/TC electronics, and battery charging under demanding street, track, and high-RPM conditions.

Whether replacing a burnt-out factory coil or restoring reliable charging performance, Arashi components meet or exceed original OEM standards for seamless plug-and-play installation.

Key Features:

High-Purity Copper Windings: Precision-wound with premium, heat-resistant copper wire to reduce internal electrical resistance and minimize thermal degradation.

Optimized Generator Core: Built using high-grade magnetic lamination materials to ensure maximum current output and stable voltage across all RPM ranges.

Direct OEM-Style Fitment: Equipped with a factory-matching wiring harness, rubber grommet, and heavy-duty 3-pin waterproof connector for a clean, bolt-on setup—no wire cutting or splicing required.

Epoxy Insulated Protection: Coated with heat, oil, and vibration-resistant insulation to prevent short circuits and breakdown caused by hot engine oil and intense high-RPM engine vibrations.

Restores Full Charging Power: Fixes common charging issues such as battery drainage, starting difficulties, electronic glitches, and dimming lights during long rides.
