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

The Piaggio 58070R complete 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 that, under the magnetic flywheel, produces the system's current and recharges the battery. It is fitted on 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.

✓ Strengths

• Original Piaggio spare part – this is the 58070R code listed in the catalog for the flywheel assembly of these engines, not a remanufactured or aftermarket part.
• 350 W, 18 poles – the power and original equipment configuration of the 250-300 Euro 3, for which the regulator and system are calibrated.
• Complete stator – copper windings, wiring, phase sensor, and connector already assembled: simply fix it to the plate and connect it.
• One code for four brands – Piaggio, Vespa, Gilera, and Aprilia, from 2005 to 2016.
• Resolves charging failure – constantly dead battery, dim lights at idle, scooter stalling after a few tens of kilometers.

Technical features

Vehicle compatibility

The 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 the VIN, and we will verify the correct code for you.

Perfect for

This is the perfect replacement part for those who own a Beverly, an MP3, a GTS 250, a Nexus, or an Atlantic with a constantly dead battery even after replacement, dim lights at idle, and ultimately, a scooter that stalls after a few tens of kilometers: if the stator no longer charges, the new battery will discharge just like the old one. It is also the part that workshops keep in stock because a single code covers four brands and the entire 250-300 Euro 3 generation, and installing the original part restores the power and calibrations for which the regulator and system were designed.

Frequently Asked Questions

Which scooters does the Piaggio 58070R stator fit?
The 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 dying: is it the stator?
It could be, but it's not the only suspect. With the engine running at speed, the voltage at the battery terminals must rise compared to when the engine is off: if it doesn't 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 change the voltage regulator?
It is strongly recommended to check it. A shorted regulator is often the cause that burned out the stator: if it remains installed, it will soon 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 advisable to replace it at the same time if its value is not within the norm.

What does "complete stator" include?
The laminated core with 18 copper windings, the wiring with the sheath, the phase sensor for ignition, and the connector to the system, already assembled as seen in the photos. It does not include the magnetic flywheel, the cover gasket, or the mounting screws, which can be reused if intact.

Can I install it myself?
It requires removing the flywheel cover and, on almost all these engines, the flywheel itself with the dedicated puller: this is a job for an equipped workshop. The tightening torques of the plate screws must be respected, and a new gasket must be reinstalled on the cover, otherwise the engine will leak oil from the left side.

Is it an original Piaggio spare part or a remanufactured one?
It is the original Piaggio spare part with code 58070R, new and never fitted, the same as provided by the manufacturer for these scooters. It is not a remanufactured or aftermarket part: on a component that must deliver 350 W continuously, original equipment windings and insulation make a difference in durability. It is shipped from Italy with an invoice.
