Piaggio 58070R Complete Stator 350W – Beverly, MP3, Vespa GTS, Nexus and Atlantic 250-300

The complete Piaggio 58070R stator is the 350 W, 18-pole generator for first-generation Euro 3 Piaggio group 250 and 300 four-stroke engines: the stationary part of the alternator which, located under the flywheel magnet, generates current for the electrical system and charges the battery. It is fitted to Piaggio Beverly 250 and 300 Tourer, Carnaby, MP3 125-250, X7, X8, and X Evo 250, Vespa GT, GTS, and GTV 250, Gilera Nexus, and Aprilia Atlantic, Sport City, SR MAX, and Scarabeo Light. Complete with wiring, sensor, and connector. Product code 58070R.

✓ Key features

• Original Piaggio spare part – this is the 58070R code listed in the flywheel group catalog for these engines; not a refurbished part or a third-party replacement.
• 350 W, 18-pole – the standard power and configuration for 250-300 Euro 3 engines, for which the regulator and electrical system are calibrated.
• Complete stator – copper windings, wiring, phase sensor, and connector already assembled: just bolt it to the plate and connect it.
• One code for four brands – Piaggio, Vespa, Gilera, and Aprilia, from 2005 to 2016.
• Solves charging issues – battery always dead, dim lights at idle, scooter cutting out after a few dozen kilometers.

Who it is perfect for

This is the spare part for those who have a Beverly, MP3, GTS 250, Nexus, or Atlantic with a battery that stays dead even after replacement, lights that dim at idle, and eventually, the scooter cutting out after a few dozen kilometers: if the stator no longer charges, a new battery will drain just like the old one. It is also the part that workshops keep on their shelves because a single code covers four brands and the entire 250-300 Euro 3 generation, and fitting the original part restores the power and calibration that the regulator and system were designed for.

Frequently Asked Questions

On which scooters can the Piaggio 58070R stator be installed?
Code 58070R is listed in the Piaggio catalog for Beverly and BV 250, Beverly and BV 300 Tourer, Carnaby 250 and 300, MP3 125 and 250, X7, X8, and X Evo 250, Vespa GT, GTS, and GTV 250 and Super GTS 300 USA, Gilera Nexus 125-300, Aprilia Atlantic, Sport City, Sport City Cube, SR MAX 125, and Scarabeo Light, as shown in the table.

The battery keeps draining: is it the stator?
It could be, but it is not the only suspect. With the engine started and revved, the voltage at the battery terminals must rise compared to the voltage when the engine is off: if it does not rise, the fault lies in the charging chain, i.e., the stator or the voltage regulator. Both should be tested with a multimeter before ordering the part.

Do I also need to replace the voltage regulator?
It is strongly recommended to check it. A shorted regulator is often the cause of a burned-out stator: 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 it together if its reading is not within the standard range.

What does the «complete stator» include?
The lamination stack with the 18 copper windings, the sheathed wiring, the phase sensor for ignition, and the connector to the system, all pre-assembled as shown in the photos. It does not include the flywheel magnet, the cover gasket, or the mounting screws, which can be reused if in good condition.

Can I install it myself?
You need to remove the flywheel cover and, on almost all these engines, the flywheel itself using a dedicated puller: this is a job for a well-equipped workshop. The tightening torques for the plate screws must be respected, and a new cover gasket must be installed, otherwise the engine will leak oil from the left side.

Is it an original Piaggio spare part or a refurbished one?
It is the original Piaggio spare part with code 58070R, new and never installed, exactly as prescribed by the manufacturer for these scooters. It is not a refurbished part or a third-party replacement: for a component that must deliver 350 W continuously, standard windings and insulation make the difference in durability. It is shipped from Italy with an invoice.
