Revised 2021 version of one of the best cylinders available including cylinder head suitable for your Piaggio Ciao, Si, Bravo, Boxer moped / moped with 12 mm piston pin.
This cast iron cylinder offers a very good increase in performance over the entire speed range and makes it one of the most popular 73.5 cc racing cylinders for Piaggio engines.
The workmanship is very clean and the alignment of the piston windows with the overflow channels and boost parts is very good. The webs in the area of the cylinder head significantly reduce the risk of piston jamming and make the cylinder extremely durable. The cylinder head with its small combustion chamber and large flat sealing surface ensures good compression. Thanks to the additional cooling fins on the sides, this racing cylinder head can dissipate the resulting heat even better and thus protects the racing set from overheating.
