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.
Technical data cylinder:
The intake manifold with diaphragm system for Dell'Orto SHA or PHBG carburetor and exhaust flange is included in the scope of delivery.
Notes:
Plugs with long thread must be used.
For Swiss 504 engines (42 mm stroke), the following modifications must be made to the cylinder:
As experience has shown that the steel diaphragm plates supplied can break, we recommend replacing them with carbonite diaphragm plates. You can find these and other suitable parts in the accessories section.
