Piaggio 191189 Side Stand O-Ring Gasket – Vespa GTS, Beverly, Liberty and X9

The Piaggio 191189 O-Ring seal is the original spare part for the side stand: the official catalog lists it in the "Stand(s)" table and requires two per vehicle. A single code that covers almost the entire Piaggio, Vespa, Gilera, and Aprilia range from the last twenty years. Product code 191189.

✓ Strengths

• Original Piaggio spare part – it is the code provided by the official spare parts catalog, not an equivalent.

• One code for 97 models – from the Vespa GTS to the Porter D120, including the Beverly, Liberty, X9, Nexus, and Runner.
• Not for the center stand – the center stand uses part 273754: here you will find the right one for the side stand.
• Black rubber – it should be replaced every time the stand is disassembled, as is done with any O-Ring.

Who it is perfect for

For those who are restoring their side stand and notice that the rubber is crushed or split: it is the low-cost part that makes the stand silent and play-free again. It is also the right item for workshops working on Piaggio Group scooters, as the same part number covers almost the entire range, making it worthwhile to keep a few in the drawer.

Frequently asked questions

How many pieces are needed for my scooter?
Two. The official Piaggio spare parts catalog indicates a quantity of 2 per vehicle in the "Stand(s)" diagram, and the same quantity is found on all models we have verified. The price shown is for a single piece: if you are refurbishing the stand, put two in your cart.

Is this the O-ring for the center stand or the side stand?
The side stand. In the "Stand(s)" diagram, the 191189 always appears in the side stand assembly, along with the fixing bolt and the return springs. The center stand uses a different O-ring, part number 273754: these are two distinct items and are not interchangeable.

Which models does the 191189 fit?
It fits 97 Piaggio Group models: Vespa GTS, GTV, Primavera, Sprint, LX, and S, Piaggio Beverly, Liberty, Fly, X8, X9, X10, and X Evo, Gilera Nexus, Runner, and GP 800, Aprilia SR Max, SRV, and Scarabeo, up to the Porter D120. The complete list including years is in the table above.

What are the dimensions of this O-ring?
The manufacturer does not publish the diameter and thickness for this part number: the spare parts catalog lists it only as "Gasket," without dimensions. That is why you won't find them written on the product sheet: we prefer to have less information than incorrect information. If you need them measured precisely, write to us and we will measure the part from our stock.

Is it an original Piaggio spare part?
Yes. It is part number 191189 from the official Piaggio Group spare parts catalog, new and never installed. It is not a third-party equivalent and not a copy: it is the same part installed by the dealership, with the same designation and catalog location.

Why is there no barcode?
Original Piaggio and Aprilia spare parts do not have a 13-digit EAN code: the identifier is the part number, in this case 191189. This is normal and is not missing information. To place an order or request verification, that number is sufficient, along with the model and year of your vehicle.
