Attention! For all Vespa tuning friends SIP has again something brand new at the start: the racing cylinder 125cc 6 Travasi for the Vespa 50-125/PV/ET3/PK/S/XL/2.
High performance 125cc cylinder kit for Vespa smallframe models. The SIP Performance cylinder helps the small Vespas to modern driving performance in the popular displacement class and is now available in the online store.
The SIP Performance cylinder 125cc has a modern layout of the overflow system. This allows for much better performance than the original 125cc cylinder on Vespa smallframe models.
- 125cc displacement
- Modern channel layout with large cross-sections
- 8-fold bolted head
- High quality piston
The 125cc class enjoys unbroken popularity. It enables the entry into motorized locomotion on two wheels. Depending on country-specific regulations, two-wheelers with 125ccm may often be moved without a motorcycle license. Sometimes a car driver’s license, special driver’s licenses from the age of 16 or inexpensive additional driver’s licenses are sufficient.
With the SIP Performance 125cc there is the possibility to build engines for such driving license regulations, which come up with adequate driving performance. The original Vespa Smallframe engines bring it only to 5.6HP and 85km / h. With the SIP Performance 125, the achievable performance is on par with the 133cc-136cc grey cast iron tuning cylinders that have been widely used since the 90s.
Important: for operation on public roads, of course, a consultation with the licensing authorities is necessary beforehand!

Questions and Answers about Vespa Tuning
Is Vespa tuning legal?
Basically, it can be said that any modification to the Vespa leads to the expiration of the operating license. However, Vespa conversions are not completely prohibited. With a proper certificate and proof of performance for the corresponding conversion parts, there is a good chance to work with the TÜV to enter the conversion parts in the vehicle file.
