Get your 50cc 2-stroke scooter starting reliably again with this Universal Parts Electric Starter Motor. Designed for Minarelli 1PE40QMB Jog-style engines, this is the motor that spins your engine over when you press the starter button. A worn or failed starter motor causes slow cranking, grinding, or a complete no-start — this is a direct bolt-on replacement that restores clean, fast starts.
The 9-spline shaft engages the starter clutch gear on the engine, and the 64mm bolt hole spacing matches the standard Minarelli Jog mounting pattern. Clockwise rotation matches the OEM spec.
