41 mm racing kit with 57 cc, suitable for your Piaggio Ciao, Si, Bravo, Boxer moped / moped.
This is the version with 10 mm piston pin.
The workmanship is clean and the casting is of good quality.
In terms of performance, however, this racing cylinder is no slouch.
The overflow ducts and the exhaust correspond to the original 38 mm cylinder. There are also no boost parts. This cylinder can therefore be regarded as a replacement for the original cylinder with slight tuning, for which no adjustments need to be made to the housing. Due to the increased displacement, we recommend that you always adjust the carburetor and exhaust accordingly in addition to the tuning cylinder. The original cylinder head can be retained, but we recommend replacing it with a 41 mm cylinder cover from the accessories range.
