Vespa Malossi 46.5mm "73cc" Cast Iron Cylinder Kit - 12 Pin carlo and Si mopedsBig cast iron cylinder kit for Vespa mopeds from Malossi. 46. 5mm bore and an absurd number of holes in the piston and cylinder. Surely a ripper. Features a 2 ring piston and Bravo style head. Will work on most Vespa models with the exception of Ciao. This will require you to bore out your stock cases or pair with a set of Malossi cases. It will not fit without modifying the stock cases. This is for 12 pin cranks! You'll have to open your engine up
