Who is this perfect for?

This is the spare part you need when your scooter no longer starts via the button: the starter motor turns slowly, gets stuck halfway through a rotation, or does not turn at all while the lights and dashboard remain on. These are symptoms of worn brushes and a damaged commutator, and on a ten- or fifteen-year-old starter, it is more cost-effective to replace it than to rebuild it. It is also the part that should be replaced if the scooter has been sitting unused for a long time with a flat battery: starting under insufficient voltage is what wears them out fastest. Installation is manageable for a workshop in half an hour, and on many models, you can access the starter motor without removing the engine.

Frequently Asked Questions

Which scooters does the 1A011611R starter motor fit?
It fits Piaggio Group 125, 150, 250, and 300 4T engines: Vespa GTS and GTS Super, GTV Sei Giorni, 946, Primavera, Sprint, LX, LXV, S and LT, and Piaggio Beverly 250 and 300, MP3 125 and 300, Liberty 125 and 150, and Fly 125 and 150. The table above lists the exact years for each model.

Does it replace part number 58142R?
Yes. The 1A011611R is the updated version of the 58142R (also seen as 58142R5) and fully replaces it. If your manual, old invoice, or the label on your removed starter lists that code, this is the correct replacement to order today.

How do I know if the problem is really the starter motor?
First, rule out the battery, starter relay, and connections: if you hear a single «click» when pressing the button and the lights suddenly dim, it is almost always the battery. If the relay clicks, the voltage at the terminals is good, but the starter motor turns slowly or remains silent, then it is the starter.

Is it original Piaggio or an equivalent?
It is an original Piaggio Group spare part, with factory code 1A011611R. Equivalent starter motors from other manufacturers are available on the market; they fit, but on a component that draws tens of amps every time it starts, original windings and brushes make a difference in longevity.

Are screws, cable, and starter relay included?
No: the starter motor is sold as a standalone complete unit, with the sealing O-ring already in place and the positive terminal stud mounted. Mounting screws can be reused from the old one; the power cable and starter relay can be ordered separately if they also need replacing.

The vehicle filter lists my scooter, but the year doesn't match: what should I do?
The compatibility table on this page is the authoritative source, as it reflects the years from the official catalog. The site's filter works by model family and may show wider intervals. If your year does not appear, send us your chassis number and we will confirm the correct part code for you.
