The solution for every Sachs rider and widescreen lover..

It is an identical copy of the original cylinder Sachs 503 AB CH / AC CH / ADV CH. The overflow channels as well as intake and outlet have remained true to the original and have not been optimized.

The appearance also remains identical and is indistinguishable from the original.
The original cylinder head can be used and works without any issues.

The cylinder also features a bore for mounting a decompressor. If this is not used, it can be capped off with a blind screw.

Warning: The flange for the exhaust is angled on this cylinder model.
