Here you will find cylinders and their spare and individual parts for Piaggio (Vespa) Ciao P, PX, SC, C24 / Si / Bravo / Superbravo / Boxer / Grillo mopeds. The most important distinguishing feature of these tuning cylinders, in addition to the standard cubic capacities of 50, 63, 65, 70 and 75 cc, is the piston pin diameter (AXE). This differs between 12 mm & 10 mm in the original cylinders and in the racing kits. The easiest way to measure this is on the piston pin or directly on the piston.
