Who it's perfect for

This is the spare part for those who feel their Vespa bottoming out on speed bumps, continuing to oscillate after a pothole, swaying in curves, or scraping the stand on turns that previously weren't an issue: these are symptoms of an exhausted shock absorber, which become more evident with a passenger or loaded top case. It's also the first sensible intervention for a second-hand GTS with many kilometers, and the part that a workshop installs when the customer wants original behavior and not a different calibration: same code, same spring, same attachments as the original equipment.

Frequently Asked Questions

Which Vespas does the Piaggio 1C004531R rear shock absorber fit?
Code 1C004531R is listed in the Piaggio spare parts catalog for Vespa Granturismo 125 and 200 L, GT 125, 200 and 250, GTV 125, 250 and 300, and for the entire GTS 125, 150, 250 and 300 family, including Super, Super Sport, Touring, HPE and Sei Giorni versions. The table above lists versions, years, and markets.

Is the price for one shock absorber or for a pair?
For one shock absorber. Vespa GT, GTS, and GTV models use two rear shock absorbers, one on each side, and code 1C004531R is valid for both: if you want to replace both, which is recommended, order quantity 2. The price indicated always refers to a single piece.

Does it come with a spring or do I need to re-use the old one?
It is complete: it comes already assembled with the black helical spring and preload collar, exactly like the factory-mounted part. There's no need to remove the spring from the old shock absorber or use a spring compressor: simply remove the worn part and attach the new one to the same mounting points.

How do I know if the shock absorber needs replacing?
Typical signs include bottoming out on speed bumps, continued oscillation after a pothole, swaying in turns, and oil traces on the rod. With a passenger or loaded top case, the defect becomes more pronounced. If one of the shock absorbers is leaking or worn out, it's advisable to replace the pair.

Is this an original Piaggio spare part or an equivalent?
It is the original Piaggio spare part with code 1C004531R, new and never mounted, the same one the manufacturer lists in the catalog for these Vespas. It is not an aftermarket shock absorber with its own calibration: the spring, travel, and attachments are those of the original equipment. It is shipped from Italy with an invoice.

How can I be sure that this is the correct code for my Vespa?
Check that your model appears in the table with the correct year and market: the GTS range covers almost twenty years and different trim levels, and in some cases the catalog specifies different codes. If your Vespa is not listed, or if you have any doubts about the year, send us your VIN and we will verify it before purchase.
