The high-quality 38 mm original cylinder is now also available exclusively with «Vertex» pistons.
This cylinder fits various Puch mopeds / mopeds such as Maxi S / N, Puch X30 NS / NL, Puch X30 NG-2A.

With this cylinder, you will reach your destination quickly and powerfully.
- The intake window has been moved slightly downwards to achieve better timing
- Lubrication holes on the piston to the piston pin.
- The inner flats on the piston were milled flat for clean guidance of the connecting rod bearing
