(2023) MiNr. 920 ** - Andorra (Fr.) - Caterpillar motorcycle Kettenkrad

The NSU Kettenkrad, officially referred to as the Sd.Kfz. 2 or Kleines Kettenkraftrad HK 101, was a unique semi-tracksuit motorcycle developed during World War II in Germany. The name "Kettenkrad" is a compound of the words "Ketten" (tracks) and "Kraftrad" (motorcycle).

Development and Construction

Kettenkrad was originally designed as a light tractor for airborne troops. Its compact size allowed it to be transported inside a Junkers Ju 52, which was crucial for rapid deployment. The vehicle was equipped with a water-cooled 1.5 litre Opel Olympia four-cylinder engine, which provided 36 horsepower. The transmission had three forward and one reverse speed, with a choice between road and off-road modes.

Deployment and Use

Kettenkrad was deployed on various fronts in World War II, including the Eastern Front, North Africa and Western Europe. Its ability to navigate difficult terrain such as mud, sand or snow made it invaluable for:

The Kettenker

• Laying communication cables
• Transport of troops and material
• Hauling light guns and other equipment

Later in the war it was also used to tow aircraft on airfields, particularly Messerschmitt Me 262 jet fighters, to save fuel.

The production of the Kettenkrad took place at the NSU Motorenwerke AG plant in Neckarsulm. A total of approximately 8,345 units were produced. After the war, production was resumed for civilian purposes, especially in agriculture, and continued until 1948.
