Forged and sealed 41 mm cylinder kit with 12 mm piston pin including gaskets and studs.
This tuning cylinder without sealing fits Puch X30 Velux and Puch X30 NG-2AH mopeds.
Please select the desired piston in the selection field.
Picture 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 at the sealing surface to the cylinder base must be filled in to ensure that the cylinder kit is tight.
We recommend using the Wekem liquid metal for this purpose, which can be found in the accessories section.
Good, inexpensive standard spare part. GPO – GOOD PARTS ONLY.
