Cylinder 50cc 38mm Sachs 504 / 505 / Hercules / KTM Athena

This cylinder of the Italian brand Athena is the result of years of development and expertise. Athena has cast this cylinder in one piece, so the timing of the cylinder and the piston can be adjusted perfectly and there will never be any compression loss between the cylinderhead and the cylinder. The set comes standard with gaskets, piston, piston pin and piston rings.

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.
