Following the end of WWII and the Allies’ victory, the Germans saw many of their factories and blueprints taken as reparations. These German intellectual properties included rockets, submarine research and even motorcycles. In fact, the DKW factory created in 1919 notably produced some lightweight 2-stroke 125cc bikes known as the time as RT-125, which were reliable and pretty efficient bikes. The Allies took the bike’s blueprints and adapted them to their taste. For instance, the British BSA created the Bantam from the RT-125. To thank Harley-Davidson for their supply of WLAs during the war, they were also gifted the blueprints, which permitted them to create the Hummer.

At the time, HD were looking for a small bike oriented towards young riders and beginners. To this end, the RT was a perfect base. In 1948, the bike was released. The bike had an air-cooled 125cc 2-stroke engine developing 3 hp. With a very low weight of 170lbs, the bike could reach about 45mph. To get more information about the S-125, please read Motorcycle Classics.

The Hummer featured in the article is in good shape for a 70-year-old lady. The seller claims that the engine has been overhauled, and the whole bike was restored with NOS parts. As we see on the pictures, the bike could need some TLC but still represents a great piece of motorcycle history.
