Piaggio 58080R Complete Stator – Beverly 400-500, X9 500, Nexus 500, Atlantic and Scarabeo

The Piaggio 58080R complete stator is the 18-pole generator for the Piaggio Group's 400cc and 500cc four-stroke maxi-scooters: it is the stationary part of the alternator which, located under the flywheel magnet, generates power for the electrical system and recharges the battery. It is fitted on the Piaggio Beverly 400 and 500, BV 500, X8 400, X9 500 and Evolution, X Evo 400, the Gilera Nexus 500, and the Aprilia Atlantic 500, Atlantic Sprint 400-500, Scarabeo 500 and Scarabeo Light. Complete with wiring, sensor, and connector. Product code 58080R.

✓ Key features

• Original Piaggio spare part – this is the 58080R part number provided in the flywheel magnet catalog for these engines; it is neither refurbished nor a third-party part.
• 18-pole – the standard configuration for 400-500cc engines, for which the regulator and electrical system are calibrated.
• Complete stator – copper windings, sleeved wiring, phase sensor, and connector already assembled: it mounts onto the plate and plugs in.
• One single code for three brands – Piaggio, Gilera, and Aprilia, from 2001 to 2011.
• Solves charging issues – battery always dead, dim lights at idle, scooter shutting off after a few dozen kilometers.

This list is based on the official Piaggio spare parts catalog (B2B area). If you have any doubts about the year or version, please send us your VIN and we will verify the correct part number.

Who is this perfect for?

It is the ideal spare part for those who own a Beverly 500, X9, Nexus 500, Atlantic, or Scarabeo 500 that has a constantly dead battery even after replacement, lights that dim at idle, and the scooter eventually shutting off after a few dozen kilometers: if the stator is no longer charging, a new battery will drain just like the old one. It is also the part that workshops keep in stock because a single part number covers three brands and all group 400-500cc models from 2001 to 2011. Choosing the original part ensures the power and calibration that the regulator and electrical system were designed for.

Frequently Asked Questions

Which scooters does the Piaggio 58080R stator fit?
The 58080R part number is specified in the Piaggio catalog for Beverly 400 and 500, BV 500 and BV 500 Tourer, X8 400, X9 500 and X9 500 Evolution, X Evo 400, Gilera Nexus 500 and Nexus SP, Aprilia Atlantic 500, Atlantic Sprint 400 and 500, Scarabeo 500 and Scarabeo 400-492-500 Light, within the years indicated in the table.

My battery keeps dying: is it the stator?
It could be, but it is not the only suspect. With the engine started and revving, the voltage at the battery terminals must increase compared to the voltage with the engine off: if it does not increase, the fault lies in the charging chain, meaning either the stator or the voltage regulator. Both should be tested with a multimeter before ordering the part.

Do I also need to change the voltage regulator?
It is strongly recommended to check it. A shorted regulator is often the cause of the stator burning out; if left installed, it will quickly burn out the new one too. It costs much less than the stator, can be tested with a multimeter in a few minutes, and it is worth replacing both if the regulator readings are not within normal range.

Is this the same stator as the 250-300cc Beverly and Nexus?
No. The 58080R is the stator for 400cc and 500cc engines: Beverly, MP3, X8, X Evo, and Nexus models with 125, 250, and 300cc displacements use a different stator with a different part number, specified in the catalog for those engines. Check the displacement on your registration document and, if in doubt, send us your VIN before ordering.

What does the "complete stator" include?
The laminated core with the 18 copper windings, the sleeved wiring, the phase sensor for ignition, and the connector to the electrical system, already assembled as shown in the photo. It does not include the flywheel magnet, the cover gasket, or the mounting screws, which can be reused if in good condition.

Is it an original Piaggio part or a refurbished one?
It is the original Piaggio part 58080R, brand new and never installed, exactly as specified by the manufacturer for these maxi-scooters. It is not refurbished or a third-party part: for a component that works continuously under the flywheel, factory-standard windings and insulation make the difference in durability. It is shipped from Italy with an invoice.
