40 mm reproduction cylinder kit for Puch Supermaxi LG1 / LG2 mopeds. This cylinder also fits Puch Maxi or Puch X30 mopeds, as it is equipped with smaller exhaust ports. In this case, however, the corresponding exhaust with a narrow outlet must be fitted.
This tuning cylinder has more displacement and a larger intake and exhaust. As a result, the cylinder has significantly more pull than its original counterpart.
The piston has two piston rings.
Note: Please observe the installation direction when assembling. The piston is inserted with the arrow pointing towards the outlet on the exhaust side.
