Remember also that there were changes made before production in some lines.
The Hercules/W2000 was originally a Shaft Drive motorcycle.

Google Translate:

Prototype of the entire W 2000 series, was first presented in October 1970 at the IFMA (International Motorcycle and Bicycle Exhibition) in Cologne. The machine is equipped with the gearbox and cardan shaft of the BMW R27, which, however, was too expensive for series production. An adapted SACHS KM 914 stationary engine was used as the engine. Location: Deutsches Museum München, in future the Center for Industrial Culture Nuremberg

The shaft drive idea was stolen from the French Advancer from 1972 I bet !
