Fitment FAQ
Will this part fit my specific model and year?
This starter motor is designed for select Suzuki GSF1250, GSF1250S, GSX1250, Yamaha MT-09, FZ-09, XSR900, and Niken 850 applications when the original starter matches the listed OEM references and 9-tooth CCW design. Please compare your original starter motor’s part number, tooth count, rotation direction, body shape, mounting points, and electrical terminal before ordering.
Do I need to match the OEM part number?
Yes, matching the OEM or reference number is strongly recommended. This starter motor replaces Suzuki references 31100-18H00, 31100-18H10, and 31100-18H11, as well as Yamaha references 1RC-81890-00-00, B7N-81890-00-00, and BFD-81890-00-00. However, OEM number alone is not enough. Please also confirm the 9-tooth gear, CCW rotation, mounting layout, shaft position, and terminal style.
What models or situations does this part not fit?
This part does not fit Suzuki Bandit, GSX1250, Yamaha MT-09, FZ-09, XSR900, Niken, or other motorcycles that use a different starter gear count, different rotation direction, different shaft length, different mounting holes, different terminal style, or different starter body. It is also not a replacement for the battery, starter relay, starter clutch, stator, ignition coil, ECU, or complete wiring harness.
What should I check before ordering?
Before ordering, please check your motorcycle’s make, model, year, engine version, original starter motor OEM number, tooth count, rotation direction, mounting hole layout, electrical terminal, shaft position, starter body length, starter body width, and available installation space. For best fitment, compare the product photos and specifications with your original starter motor before purchase.
