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

The intake manifold and exhaust flange are included in the scope of delivery.

Plugs with a long thread must be used.

Technical data cylinder:

  • Ø inside intake manifold: 15 mm
  • Connection diameter intake manifold: 20 mm
  • Ø inside exhaust flange: 20 mm

Attention: For Swiss 504 engines (42 mm stroke), the following modifications must be made to the cylinder:

  • Adjust 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.
  • In the model with an external clutch lever, the intake must be extended, otherwise the carburettor may come into contact with the clutch lever.

Quality product from the Italian manufacturer Athena.
