SIP 19874600 Thermal unit cylinder kit

Cylinder Kit PIAGGIO by SIP 125 cc for Vespa 125 VNB/GT 125 cc for Vespa 125 VNB/GT/GTR 1°/Super Ø 52,5mm, cast iron, 2 ports, stroke 57mm, 2 piston ring(s), 3rd port closed with spacer, Grade A - perfect repair For race use only. Not admitted in the area of the German StVZO! The older your vehicle is and the more mileage on your motor, the more reasons for replacing your original cylinder. The born is worn and has siezed a few times or is irreparably damaged. We offer you low priced standard cylinder kits, 1:1 with the original. Measurements, performance and appearance are identical. We also offer you PIAGGIO cylinder kits, as long as we can still get them. If they are PIAGGIO ones, we will name them in that way. The kits come with complete pistons including 2 piston rings, but without cylinder head and 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.'
