Racing Exhaust SITO Plus for

Vespa PK80-125 S/PK100-125XL
with BSAU mark, dent is


The SITO Plus is the classic amongst road tuning exhaust systems. These series similar models are visually similar to the original, but they get respectably more power out of your Vespa.


This racing exhaust system offers impeccable perfect fit and a pleasant hearty sound. Durability is a guarantee with the SITO Plus, made of solid steel sheet metal and painted black.


The PK50 version, thanks to E-Norm, is street legal. A small restrictor in the jointpipe throttles speed to 45 km/h. When removed, performance increases and inspection, depending on your country, may or may not allow it. This offers a decent possibility to tune up a PK and is often used in combination with larger cc cylinders. The SITO Plus is also the only available racing exhaust for the Vespa PK50 S/SS/XL N Automatica/Plurimatic.


Conclusion: Sporting road tuning exhaust in original optics


Sport exhaust / made of steel

Steel, painted black, shaped practically the same as the original, exact fit, partially with E-Norm.

Jets should be adjusted.


SIP TIP: Use of high temperature proof exhaust paint extends durability of exhaust system. The SIP exhaust stub (part No 21601100) is a perfect addition.


SIP community user ‚Maanuu‘ (about 24990000): „YEAH!! Great part, Vespa pulls better now, top speed about 10 km/h faster…. of course the sound is great now, only for those who want an inconspicious racing exhaust“


SIP community user ‚vespaamsterdam‘ (about “This exhaust is good to combine with 75cc Pinaso cylinder. But when using aluminium outlet pipe, its problaby will loose due vibration. Its better to use steel outlet pipe with this exhaust. Use this item with Art.Nr. 21601600 and and original exhaust gasket for good performance.”
