Who it is perfect for

The 0641 bracket is the part needed by anyone reinstalling a torpedo-style exhaust on a Vespa smallframe who finds themselves with a bent, stripped, or rusted mount. It is a typical restoration spare part: it costs a few euros, avoids having to buy the entire exhaust, and restores the original rigid fastening to the silencer. Suitable for workshops, restorers, and vintage Vespa enthusiasts.

Frequently asked questions

Which Vespa models is the 0641 bracket for?
It fits Vespa smallframe models: Vespa 50, Vespa 90, Vespa 125 Primavera, and Vespa 125 ET3, which are the models for which the manufacturer provides the SITO 237 or 238 torpedo exhaust. It is not the support for Vespa PX, PK, or modern wide-frame Vespas.

Which exhausts is this the right spare part for?
For SITO 237 and SITO 238 torpedo exhausts. The 237 is the system for the Vespa 125 ET3 and 125 Primavera, while the 238 is for the Vespa 50 and 90. Code 0641 identifies the bracket only: the exhaust is not included.

Are the fastening screws included?
No. The package contains the bracket, and no catalog source indicates any bolts, nuts, or rubber grommets with the part. If you are dismantling an old system, it is worth getting new screws and gaskets, as the original ones are almost always corroded by heat.

Is it an original part or an aftermarket equivalent?
It is the official catalog spare part from the company that makes the exhaust, SITO, which is now part of LeoVince. It is not an original Piaggio spare part: the torpedo exhaust is a SITO system, and this is the bracket provided by its own manufacturer, not a third-party adaptation.

What material is it made of and how much does it weigh?
It is a metal plate with a black paint finish, as seen in the photo of the actual part. The manufacturer does not publish the alloy or the dimensions, so we do not list them. The only data certified by catalog sources is the weight: 0.105 kg, which is 105 grams.

How can I be sure it's the right bracket?
Check the stamped code or the label on your exhaust: if it is a SITO 237 or 238, this is the intended bracket. If in doubt, send us a photo of the old support and your Vespa's chassis number, and we will confirm if the part matches.
