125cc aluminum Racing Cylinder with powerful layout for all Vespa Largeframe Models from 125 to 150 cc.
With the SIP Performance 125 Cylinder，all Vespa Largeframe scooters can be transformed into a two-wheeler in the 125cc class with modern performance.
This makes it particularly suitable for Vespa riders who have a license with a 125cc engine capacity limit.
Powerful 125cc Cylinder
Compatible with 2- and 3-channel Engines
Coated aluminum Cylinder
Unfortunately，classic 125cc scooters in their original condition are no longer up to date in terms of performance.
With the SIP Performance 125 Racing Cylinder，this can be easily changed and even 125cc license holders can safely keep up with the traffic.
The Cylinder is made of aluminum and has a coated raceway.
The Cylinder draws its power from its sophisticated transfer system.
The mixture enters the combustion chamber through six transfer ports and escapes back into the Exhaust through three exhaust ports.
The head is fitted with 8 fittings and additionally sealed with an O-Ring.
The exhaust is made of steel and is bolted to the Cylinder.
The Piston is coated to protect the piston skirt during the running-in phase.
The Cylinder is always installed with a 4mm thick Spacer between the Cylinder and the Crankcase.
Two different Spacers are included in the kit.
One is for mounting on a three-channel casing，the other allows the Cylinder to be mounted on a two-channel casing.
The scope of delivery includes paper gaskets of different thicknesses for both types of housing，which can be used to adjust the height of the Cylinder.
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.
Important：for operation on public roads，it is of course necessary to consult the licensing authorities beforehand！ Depending on the country-specific regulations，a complex individual approval is usually necessary.
Without a special approval by the responsible approval authorities，the operation of the Cylinder on public roads is prohibited.
