Magneto Stator for BMW F650GS F700GS F800GS F800R | 12318524422

Product Overview

Replacement 18-coil magneto stator / generator stator for selected BMW F-Series parallel-twin motorcycles, including compatible F650GS, F700GS, F800GS, F800R, F800S, F800ST, and F800GT applications.

Designed for the BMW 650/700/800 twin-cylinder platform, this stator measures approximately 115mm outer diameter and 54mm inner diameter.

It is designed as an aftermarket replacement for compatible BMW charging-system stators associated with BMW 12 31 8 524 422 / 12318524422 and related references.

Before ordering, verify the OEM number, exact motorcycle model and year, stator dimensions, mounting points, wiring, connector, and original stator appearance.
