Not so nice 
Cast iron cylinder with 50 cc displacement, suitable for your Piaggio Ciao, Si, Bravo and Boxer moped / moped with 12 mm piston pin.
Mäsig-läsig! – We strive to offer you the widest range of moped spare parts. However, this product is of rather poor quality and is not recommended by us. Should you nevertheless choose this item, we can understand you, but do not grant you any warranty or exchange.
The cylinder is not cleanly finished and occasionally has chips and general manufacturing defects. In contrast to the original cylinder and other replicas, the exhaust and the overflow channels are significantly smaller and therefore the power output is correspondingly low.
Note: Check the piston ring joint before installation using a reed gauge. This should be between 0.15 - 0.4 mm to prevent the piston from jamming.
