In 1893 Edouard Scheffer and Victor Donzelot made their first bike for the Swiss military in their new factory under the name Sheffer Freres.

In 1967 Ducati's successful 350 scrambler engine was selected for use in the new Swiss military motorcycle.

The steel exhaust pipe and muffler were built to run almost silently and the whole assembly is sprayed with aluminium.

The oil filler cap changed to a longer tube to make filling easier.

One oddity is that the frame has a lug for a standard Ducati side stand, but one was never supplied by the factory.
