High-quality 43 mm gray cast iron racing cylinder compatible with your Piaggio Ciao, Si, Bravo, or Boxer moped.
The racing cylinder, with a displacement of 65 ccm, is ideal for an everyday tuning setup. The tuning cylinder features 6 overflow channels, which ensure consistent power across the entire RPM range.
Piston pin diameter: 10 mm
Notes:
To achieve optimal performance, the intake port on the engine block and the area around the overflow channels should be modified accordingly. A tutorial for modifying the intake port is linked below.
You should also use at least a 12/12 carburetor.
It is recommended to install a cylinder head with a larger diameter. Please note the installation direction during assembly. The piston is installed with the arrow pointing toward the exhaust on the exhaust side.
You can find compatible cylinder heads, replacement pistons, and oil mixture in the accessories section.
