Revised 2021 version of the well-known cylinder kit from Malossi for Piaggio Ciao, SI, Bravo, Boxer and Grillo mopeds / mopeds.
This is the version with 10 mm piston pin.
This cast iron cylinder with 73 cc, often also known as 75 cc, offers a very good increase in performance over the entire speed range.
The workmanship is very clean and the matching of the piston windows to the overflow channels and boost parts is also very good. The webs in the area of the cylinder skirt significantly reduce the risk of piston jamming and make the cylinder extremely durable.
With the reworking, the triangular shape of the overrunner was adapted to a longitudinal shape. As a result, the cylinder fits much better on racing bikes such as the Polini Speed Engine.
