About this model
About the Hercules K 125
The Hercules K 125 is a light military motorcycle from the West German manufacturer Hercules (Nuremberg), produced from approximately 1970 to 1985. It was used by the Bundeswehr (BW version) and several other Western European armed forces for liaison and light logistics duties. The 123cc air-cooled two-stroke engine produces modest power but is extremely easy to maintain in the field. The motorcycle is compact and robust, available in two variants that differ in front wheel suspension design.
The Hercules K 125 is today a sought-after classic military motorcycle among collectors and historical motorcycle groups. Its simple construction makes it accessible for restoration, and original parts circulate through military surplus networks and specialist Hercules clubs. It rivals the DKW Hummel and Zündapp KS 50 Bundeswehr versions in collectible status.

Before you buy
What to check before buying
- Check the two-stroke cylinder bore and piston for wear; after more than 50 years, a full engine rebuild is overdue on high-mileage examples.
- Inspect the 6V electrical system for corrosion and poor contacts; military storage conditions increase the risk of oxidation.
- Check originality of the paint finish and front mudguard markings; restored examples are less valuable than preserved originals.
- Ask for provenance and military administrative papers; genuine BW examples are better documented than civilian K 125 variants.
