Fitment FAQ
Will this part fit my specific model and year?
This starter motor is designed for select Yamaha V Star 950, XVS950, and XVS1300CU Stryker applications when the original starter matches OEM 5S7-81890-00 or 5S7-81890-10 and the 9-tooth CW design. It may also fit select V Star 1300 / XVS1300 applications, but the original starter motor must be checked before ordering.
Do I need to match the OEM part number?
5S7-81890-10 is commonly shown as a later or superseding Yamaha starter motor reference for 5S7-81890-00 on many OEM parts diagrams. For best fitment, compare your original starter number, tooth count, rotation direction, body shape, mounting points, and terminal position before ordering.
What models or situations does this part not fit?
This part does not fit Yamaha V Star, Bolt, Road Star, Royal Star, Raider, Stratoliner, Warrior, R6, FZ, MT, or other Yamaha 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, market version, original starter motor OEM number, tooth count, rotation direction, installation hole distance, electrical terminal, shaft position, starter body diameter, and available installation space. For best fitment, compare the product photos and specifications with your original starter motor before purchase.
