Cylinder kits to replace worn original cylinders.
Standard kits in 1：1 original design，some also PIAGGIO，including complete Piston.
The older a vehicle is and the more kilometers the Engine has run，the more likely it is that the original Cylinder will need to be replaced.
Cylinder bores are often worn，have piston seizures or seizures behind them or are run-in.
Inexpensive standard cylinder kits are available that correspond 1：1 to the originals - dimensions，performance，appearance and fit are identical.
Where available，PIAGGIO cylinder kits are also offered，which are marked accordingly.
Scope of delivery：Cylinder with complete Piston incl.
2 Piston Rings，without Cylinder Head and without Gaskets.
A powerful，high quality alternative to the more usual 2-transfer port cylinders available are our reworked OE PIAGGIO VESPA PX125/150cc cylinders，as well as the even more powerful 2-port version of the 177cc cylinders produced by POLINI and DR.
The boost ports of these cylinders have been sealed and the transfer of fuel gas is provided by the ports of the same name，located on both sides of the bore.
No further modification of your crankcase is necessary for immediate use of these cylinder kits，making them the ideal plug and play tuning option for all VESPA 125 VNB/GT/GTR/150 VBA/VBB/GL/Sprint/T4 and Super models.
If your crankshaft has a bush，instead of a bearing at the small end，it will also need replacement.
Conclusion：Attractively priced cast iron cylinder，ideal for your daily runabout.
If you wish，this cylinder can easily be further tuned with the addition of a 24mm carb，a reworked inlet port，a race crankshaft and a SIP Road exhaust.
SIP-TIP：For added power and reliability for your touring setup a race crank，expansion chamber exhaust，24mm carb and an electronic ignition kit from VESPATRONIC can be included.
Robert Kremer，ScooterandSpareparts Kissing，November 2011：
“I built this reworked POLINI 2-transfer cylinder into a scooter for one of my customers.
He is more than happy.
The scooter accelerates strongly and is also very reliable over long distances.
A more than adequate alternative to the PINASCO version.”
