Expanded 41 mm cylinder kit with 10 mm piston pin including gaskets and stud bolts.
This tuning cylinder without sealing fits Puch X30 Velux and Puch X30 NG-2AH mopeds.
Please select the desired piston in the selection field.
Figure 1 shows the Meteor piston with molybdenum coating manufactured for swiing. This is characterized by its high-quality and precise workmanship.
The piston is more durable and provides minimal additional power compared to the standard piston, which can be seen in Figure 2.
Attention: On Velux engines, the small slot in the sealing surface at the base of the cylinder must be filled in to ensure that the cylinder kit is tight.
The Wekem liquid metal, which can be found in the accessories, is recommended for this purpose.
