We bought this Enduro motorcycle directly from the German Bundeswehr (military. You don’t see the K-180 versions so often. They mostly used the smaller K-125 models. Like their civilian cousin, they have the single cylinder, 2-stroke Sachs motor. The K-180 was in excellent shape. We have had both models. The photo in the forrest is of the Hercules K-125. These were used exclusively by the German Bundeswehr.
