Racing cylinder of the Athena brand for Sachs 504 (with adaptations), 505 & 508 engines, which were installed on Hercules Prima M, 2, 3, 4, 5 and Optima mopeds / mopeds, among others.
Thanks to the large intake, overflow and exhaust, this tuning cylinder provides a considerable increase in performance.

The intake manifold and exhaust flange are included in the scope of delivery.
Note:
Plugs with long thread must be used.
The following modifications must be made to the cylinder on Swiss 504 engines (42 mm stroke):
- Adjust the cylinder base and gasket as shown in Figure 5 .
- The cylinder base must be turned off so that the compression is adjusted again due to the shorter stroke, we recommend setting a crushing edge of 0.8 - 1.0 mm.
- On models with an external clutch lever, the intake must be extended, otherwise the carburetor may come into contact with the clutch lever.
