44 mm diameter racing cylinder kit, compatible with Tomos Sprint, Quadro, FunSport, and Classic mopeds equipped with an A35 engine.
This reliable everyday cylinder impresses with its suitability for daily use, though it doesn’t compete at the top level.
To get the full performance out of the 65 cc tuned cylinder, we recommend installing a racing exhaust and a matching carburetor.
The package includes the gray cast iron cylinder and the complete piston. The gaskets for the racing cylinder are not included.
Note: We recommend that you check the edges inside the cylinder and lightly deburr them if necessary, as they may occasionally be slightly sharp. Please observe the installation direction during assembly. The piston is installed with the arrow pointing toward the exhaust on the exhaust side.
You can find alternative racing cylinders and the matching gasket set in the accessories section.
