Product Overview
This 9T CW electric starter motor is designed as a replacement starter motor for compatible Yamaha CZD250 X-MAX250 and CZD300 X-MAX300 scooter models using OEM reference number B74-H1890-00.
The starter motor provides the cranking power needed to start the engine. If your scooter has slow cranking, clicking when pressing the start button, intermittent starting failure, or the starter motor no longer engages properly, replacing a worn starter motor may help restore reliable starting performance.
Built with a 9-tooth drive gear and clockwise rotation design, this starter motor is made for direct replacement use when the OEM number, tooth count, rotation direction, mounting points, and overall body shape match your original part.
