9-Tooth Starter Motor for Yamaha YZF-R6 R6S FZ6 5EB-81890-00

Product Overview

Replace a worn, weak, noisy, or failed starter motor with this electric starter motor, designed for select Yamaha YZF-R6, YZF-R6S, FZ6, and FZ6 Fazer motorcycle applications using OEM reference number 5EB-81890-00-00.

The starter motor helps crank the engine when the electric start button is pressed. A failing starter motor may cause slow cranking, clicking, intermittent starting, no-crank issues, grinding noise, or failure to start even when the battery is fully charged.

This replacement starter motor is built with high-grade copper coil winding, a reinforced outer shell, and a sealed structure based on supplied product data. Please compare your original starter motor’s OEM number, tooth count, rotation direction, mounting points, electrical terminal, body shape, gear position, and overall dimensions before ordering.

Please confirm your original starter motor matches OEM 5EB-81890-00 or 5EB-81890-00-00 and the overall physical design before ordering.
