Description

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.

Specifications

Bolt Hole Spacing: 64mm
Bolt Hole Diameter: 7mm
Shaft Diameter: 9mm
Splines: 9
Rotation: Clockwise
Engine: Minarelli 1PE40QMB 50cc 2-stroke

Compatibility

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.
