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.
- Bolt Hole Spacing: 64mm
- Bolt Hole Diameter: 7mm
- Shaft Diameter: 9mm
- Splines: 9
- Rotation: Clockwise
- Engine: Minarelli 1PE40QMB 50cc 2-stroke
Fits Minarelli 1PE40QMB and Jog-style 50cc 2-stroke engines, including scooters from Yamaha, MBK, Aprilia, Derbi, and other brands using the Minarelli horizontal 50cc 2-stroke platform with a 9-spline starter shaft.
Fitment Tip: Before ordering, verify your existing starter has 9 splines on the shaft and 64mm bolt hole spacing. Some Jog-style engines use a 10-spline or 11-spline starter — spline count must match your starter clutch gear.
