High-performance cylinder kit in the 125cc class for Vespa smallframe models.
The SIP Performance Cylinder helps the small Vespas to achieve modern performance in the popular displacement class.
The SIP Performance Cylinder 125cc has a modern layout of the transfer system.
This allows significantly better performance to be achieved than with the original 125cc Cylinder on Vespa Smallframe Models.
125cc displacement
Modern port layout with large cross-sections
8-fold bolted head
High-quality Piston
The 125cc class continues to enjoy unbroken popularity.
It enables entry into motorized locomotion on two wheels.
Depending on country-specific regulations，125cc two-wheelers can often be ridden without a motorcycle license.
Sometimes a car driving license，special driving licenses from the age of 16 or inexpensive additional driving licenses are sufficient.
With the SIP Performance 125cc，it is possible to build engines for such driving license regulations that offer adequate performance.
The original Vespa Smallframe Engines only deliver 5.6 hp and 80 km/h.
With the SIP Performance 125，the achievable performance is on a par with the 133cc-136cc cast iron tuning cylinders that have been widely used since the 1990s.
Important：for operation on public roads，prior consultation with the licensing authorities is of course necessary！
