✓ Key features

• Complete system, manifold included – silencer and manifold in a single item: no need to order anything else to replace the exhaust.
• Original-type silencer – the Sito technical data sheet classifies it as «original-type», not sporty: the power delivery curve and noise levels remain the same as stock.
• Black painted steel – heat and corrosion-resistant finish, faithful to the original Vespa aesthetic.
• BSAU homologated – not a track exhaust: it is a road-legal exhaust.
• Direct cylinder attachment – mounts to the original seat, replacing the stock exhaust.

Vehicle compatibility

This list is as declared by the manufacturer for item 0237. If you have any doubts, send us your Vespa's frame number and we will verify the correct code.

Who it is perfect for

It is the ideal exhaust for anyone getting a Primavera or ET3 back on the road without wanting to alter its character. The original exhaust on these Vespas is almost always the most worn-out piece: rusted inside, holes in the belly, and a loose bracket. This one replaces it one-to-one, with the same torpedo shape and the same black finish. Since it is BSAU homologated, it remains a street-legal bike, not a show-piece with an open exhaust.

Frequently asked questions

Which Vespas does the Sito 0237 exhaust fit?
It fits the Vespa 125 ET3 and Vespa 125 Primavera, the two vintage 125 two-stroke models for which LeoVince lists this item. It is not the exhaust for the modern Primavera from 2013 onwards, which is a completely different vehicle: check the frame number on your registration document before ordering.

Is the manifold included or sold separately?
It is included. The Sito technical data sheet for item 0237 states «silencer complete with manifold»: the package contains the silencer and its manifold with the cylinder connection, ready to be fitted. Only gaskets and bolts remain to be sourced, as they are not part of the kit.

Is it road-legal?
Yes: item 0237 features BSAU homologation, so it is an exhaust for road use and not a race-only end can. The silencer is classified by the manufacturer as «original-type», so the noise levels remain the same as stock.

Does it change performance compared to the original exhaust?
It is an original-type replacement, not a tuning exhaust: it is designed to restore the Vespa's stock power delivery, not to increase it. LeoVince does not declare any power or torque increases for this item, and we do not report any.

What material is it made of and how does it hold up over time?
It is made of steel with heat-resistant black paint, with an aluminium mounting bracket. It is the same solution as the factory exhaust: it should be kept clean and dry, especially in the area of the bracket and the curve, where moisture accumulates if the Vespa is left standing for long periods.

How can I be sure it is the right one for my Vespa?
Check the model and years in the compatibility table and compare them with your vehicle's frame number. If your Vespa is not listed, or if the engine has been modified from the original, write to us with your frame number: we will check the LeoVince catalogue and confirm if this is the correct exhaust.
