Piaggio 259832 Fuel Tank Cap – Vespa LX and GTS, Liberty, Beverly, MP3 and Zip

The Piaggio 259832 fuel tank cap is the plastic screw cap, with the embossed GASOLINE lettering, that closes the fuel filler neck on almost the entire range of Piaggio Group scooters: Vespa LX, S, GTS and Primavera, Liberty, Fly, Beverly, MP3, Zip, Typhoon, Gilera Fuoco and GP 800, Aprilia Sport City ONE and Scarabeo. In the official Piaggio spare parts catalog, it is listed as "Fuel tank cap", in the "Fuel tank" section, in quantity 1.

✓ Strengths

• Original Piaggio spare part – this is the code prescribed by the manufacturer in the catalog, with the correct thread pitch and stop.
• A single code for almost the entire catalog – the same cap covers Piaggio, Vespa, Gilera, and Aprilia, from 50 to 800 cc: if you have multiple vehicles in the family, it fits all of them.
• Complete screw cap – it comes pre-assembled and ready to screw on, no key or tools required.
• Lobulated edge – the shaped crown provides grip even with gloves or wet hands.
• Part that gets lost and damaged – it is one of the most requested spare parts: it gets left at the gas station, stripped, or cracked by the sun.
• Seal that holds again – an old cap that doesn't screw on properly lets water into the tank and allows gasoline odor to escape from under the seat.

To check together

• The cap gasket – code 258160, in the same section: this is what seals against vapors.
• The fuel tank flap – on Beverly, MP3, and Vespa, the cap is under a lockable flap: if that is no longer closing, the spare part is a different code.
• The oil mixer cap – on 2-stroke engines, this is a different, smaller part with a different code: on Vespa PX, it is the 102585.

Who it's perfect for

It's the most common and most purchased spare part there is: the cap left at the gas station, the stripped one that no longer screws on, the sun-bleached one that crumbles in your hand. If you ride a Vespa LX, a Liberty, a Beverly, or an MP3 and the cap is missing or no longer sealing, this is the original one you need — and given how many models it covers, it's also a good part to keep as a spare in the workshop.

Frequently Asked Questions

Is this cap suitable for my Vespa LX 125?
Yes: the Piaggio catalog indicates the 259832 for the Vespa LX 125 in all versions, from 2006 to IGET up to 2023, and it is the same cap for LX 50 and 150, Vespa S, LXV, Primavera, Sprint, GTS, and GTV. It is the most common cap in the Piaggio range.

What is the exact name in the official catalog?
"Fuel tank cap", code 259832, in the "Fuel tank" section, quantity 1. The position in the section varies by model.

Does it have a key or a lock?
No: the 259832 is a screw cap without a key. On many scooters, security is provided by the external fuel tank flap, which opens with the ignition key and is a separate spare part.

Is it the fuel cap or the oil cap?
It is the fuel tank cap — you can recognize it by the embossed GASOLINE lettering. On 2-stroke engines with a separate mixer, the oil cap is a different, smaller part with a different code.

Is it also suitable for Aprilia and Gilera?
Yes. The same code is prescribed in the catalog for Aprilia Sport City ONE 50 and 125, SR Motard 50 and 125 and Scarabeo Light 250, 300 and 400-500, and for Gilera Fuoco 500, GP 800, Stalker, Storm and Ice: these are brands from the same group and share the filler neck.

How is it installed?
By hand, without tools: unscrew the old one counter-clockwise and screw on the new one until it stops, using the lobulated crown for grip. If the old cap was stripped, also check the filler neck thread before reassembling.
