Shipping notice: truck drivers' strike in Italy
Updated 19/10/2026
Since 16 October, truck drivers protesting against high diesel prices have been blocking roads and ports in Southern Italy (Campania, Calabria, Sicily, Puglia, Basilicata), and the protest could spread to the rest of the country. The strike affects all our shipments, in Italy and abroad: Poste Italiane is currently not collecting parcels, while BRT and DHL are collecting as usual but deliveries may be delayed in some areas.
- Italy we ship with BRT and DHL · possible delivery delays
- European Union for now we ship with DHL only · possible delays
- Non-EU countries (customs) shipments temporarily suspended: they will leave as soon as Poste Italiane resumes collections
We apologise for any inconvenience and thank you for your patience.
This order ships outside the European Union and is subject to customs clearance in the destination country.
Export formalities and costs from Italy are on us and are already included in the price.
Import duties, taxes and clearance fees in the destination country are payable by the buyer. They are not included in the product price or the shipping cost, and we cannot calculate them: they are set by the customs authority of the destination country.
The carrier will not release the parcel until the recipient pays these charges. If the shipment is refused or the charges are left unpaid, the parcel is returned to us and shipping, return and any customs costs are deducted from the refund.
The original Kymco 31120-KBN-9000 alternator stator (internal code 00103204) is the OEM replacement part factory-fitted on Kymco MXer 125, MXer 150 quads and other 125/150 4T models with the same engine base, such as MXU 150 and Maxxer 150. It is the component of the electrical generation system (alternator / flywheel magneto): the fixed winding that, coupled with the rotor, produces the current needed to power ignition, lighting system, battery charging, and the CDI unit.
