New! Polini cylinder set complete with cylinder head by Polini

The cylinder head and piston are custom-made by Polini's design department for the 65cc Puch Polini cylinder! It doesn't get any better than this! This set has been specially designed by Polini for optimal use with the Polini Big Valve 4-valve carbon reed valve and Polini CP 21mm with filter on a Puch Maxi / X30 with E50 / Z50 / ZA50 engine. Of course, the cylinder also fits on other types where the normal Maxi cylinders also fit.

  • One of the fastest aluminium cylinder for Puch Maxi E50, now improved in one package!
  • Polini cylinderhead (211.0608). Use a long thread spark plug, for example the NGK B9ES.
  • Polini 65cc 43.5mm cylinder with nicasil wall (144.0150)
  • Special modified Polini piston for this set (piston pin 12mm)
  • Carbon reed valve (213.0017)
  • Manifold (20mm outer diameter)
  • Complete with gaskets 
  • Cylindersleeve outer diameter: 48mm
  • Polini number 144.0151

Attention! Very sensable cylinder!

Fit the cylinder with 8 Nm, fit the gaskets in the intake pipe with liquid gasket and do not tighten too tightly. Then you will have a cylinder that lasts a long time and is very fast.

Before mounting

We always advise to check and clean the cylinder before installation and to finish the ports in the cylinder with a 1000 grit sandpaper. This way the edges are no longer too sharp because of the Nicasil coating, this will considerably extend the life of the cylinder / piston.


The cylinder is compatible for use on a Puch Maxi S / Maxi N / Maxi K / Maxi P / X20 / X30, Korado, Manet and KTM hobby with E50 / Z50 / ZA50 engine. Just note that you may have to make some modifications. Want advice on whether this cylinder fits your moped? Please contact us.
