Fitment FAQ
Will this part fit my specific model and year?
This starter motor is designed for select Kawasaki KLF300 Bayou 300 applications when the original starter matches one of the listed reference numbers, such as 21163-1080, 21163-1115, 21163-1141, 21163-1249, or 128000-1490. Please compare your original starter motor’s part number, gear count, rotation direction, mounting hole spacing, body shape, 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 cross-references with Kawasaki 21163-1080, 21163-1115, 21163-1141, 21163-1249, and 128000-1490. However, OEM number alone is not enough. Please also confirm the gear count, rotation direction, mounting hole spacing, terminal position, shaft design, starter body shape, and available installation space.
What models or situations does this part not fit?
This part does not fit Kawasaki Bayou, Prairie, Lakota, Brute Force, Mule, Mojave, KFX, or other Kawasaki ATV models that use a different starter motor number, different 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, CDI / ECU, or complete wiring harness.
What should I check before ordering?
Before ordering, please check your ATV’s make, model, year, drive type, original starter motor OEM number, gear count, rotation direction, mounting hole spacing, electrical terminal, shaft position, starter body length, starter body shape, and product photos. For best fitment, compare this starter motor directly with your original unit.
