Passform-FAQ
Passt dieses Teil zu meinem spezifischen Modell und Baujahr?
This starter motor is designed for select Suzuki KingQuad 450 / LT-A450X applications when the original starter matches OEM 31100-11H00 or 31100-11H00-000 and the 9T starter design. Please compare your original starter motor’s part number, gear count, body shape, mounting points, and electrical terminal before ordering.
Muss ich die OEM-Teilenummer verwenden?
Yes, matching the OEM or reference number is strongly recommended. This starter motor replaces Suzuki 31100-11H00 and 31100-11H00-000. However, OEM number alone is not enough. Please also confirm the 9-tooth / 9-spline drive, mounting hole spacing, installation gear diameter, shaft position, starter body shape, and terminal style.
Für welche Modelle oder Situationen passt dieser Teil nicht?
This part does not fit Suzuki KingQuad, QuadRunner, Vinson, Eiger, Ozark, LTR450, LTZ400, or other Suzuki ATV models 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, CDI / ECU, or complete wiring harness.
Was sollte ich vor der Bestellung überprüfen?
Before ordering, please check your ATV’s make, model, year, trim version, EPS / Power Steering configuration, original starter motor OEM number, tooth count, mounting hole spacing, installation gear diameter, 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.
