Technical specifications

Vehicle compatibility

This list is as declared by the manufacturer for item 0251. If you have any doubts, send us your Vespa's frame number and we will verify the correct code.

Who it is perfect for

This is the exhaust for those who use their PK on the track or in traffic-free rallies, and for those tuning a PK 125 engine who want a sports-range Sito Plus exhaust instead of the original. It is not the right part for road-legalizing a registered Vespa: for that, a homologated exhaust is required, which the manufacturer clearly excludes here.

Frequently asked questions

Which Vespas does the Sito Plus 0251 exhaust fit?
It fits the Vespa PK 125 and Vespa PK 125 XL, the two versions of the two-stroke PK 125 frame for which LeoVince specifies this item. The PK 125 covers the S and S Automatica versions as well, while the XL is the VMX6T frame code produced from 1986 to 1990.

Can I use it on the road?
No. LeoVince declares item 0251 not homologated and intends it exclusively for use in closed-circuit competitions. A homologated exhaust is required on public roads: if your PK is registered and driven, this is not the appropriate replacement.

Is the header included or must it be bought separately?
It is included. The manufacturer's datasheet describes the kit as complete and specifies that no additional parts are required: in the box, you will find the muffler with its header. You only need to provide your own gaskets and bolts, which are not part of the kit.

How much power do I gain compared to the original exhaust?
LeoVince does not declare power or torque increases for this item, and we do not report any. The difference compared to the original is that it belongs to the Sito Plus sports range and is not homologated: the performance on your engine depends on how it is tuned.

What material is it made of and what is the finish?
It is made of steel, with a heat-resistant electrostatic paint treatment: this is the finish LeoVince provides for the Sito Plus line. It should be kept clean and dry, especially in the bend and connection areas, where moisture can accumulate if the Vespa remains stationary for a long time.

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 catalog and confirm if this is the correct exhaust for your bike.
