Cylinder 70cc Metrakit by GPO Puch Maxi, X30 and other models
This Good Parts Only. Metrakit cylinder is an optimized version of the standard 65cc Metrakit cylinder. This 70cc variant is an aluminum cylinder with a cast-iron liner and features optimized port timings As a result, this cylinder delivers strong torque while also providing a good top speed.
- Aluminum cylinder with cast-iron liner
- Includes piston (12 mm piston pin) and gasket set
- Very strong cylinder with plenty of torque
- The cylinder features a large intake port; the use of a 15 mm or 17 mm carburetor is recommended
- Cylinder base outer diameter: 48 mm
- The cylinder shape does not fully match either the old or the new model. A new-model cylinder head is the best match.
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.
Models
- 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.
