Tornax was a motorcycle manufacturer from Wuppertal, Germany that was founded in 1922 by Ernst Wewer, but began motorcycle production in 1926. Wewer was a racer, and recruited other racers to help quickly build a name for Tornax (a play on the word for Tornado). Like many manufacturers at the time, they did not produce their own engines, instead using British JAP (J. A. Prestwich) engines of various capacities. Their first machine was a 600cc single called the I-26. In the beginning, Tornax used the year of production in their model names rather than displacement or catchy names. Also unlike other manufacturers, Tornax started with large machines and later went to smaller displacement models. peaking with the 1,000 cc four stroke III-31 SS, which produced a claimed 76hp, and was claimed to be the fastest machine in the world. It was a large impressive machine, but an expensive one with bad timing in the market given the depression. Tornax survived the 1930s by first producing smaller machines, and then reducing its output to a single 600cc model using an engine from German supplier, Columbus. It also moved away from alphanumeric model names and adopted catchy names like Tornado, and Rex (which interestingly utilized a DKW engine), and Schwarze Josephine.

The factory was destroyed in WWII, but Tornax resumed production in 1948. Ironically, they resumed with a 125cc two-stroke single cylinder model. This was followed by a  175cc, a 250cc and then a twin cylinder 250cc Earles Fork model producing 15hp. A far cry from their 1,000cc 76hp peak! Then in 1954, Tornax purchased the rights to german engine-builder Opti’s four stroke machines to eliminate contracts with ILO, Columbus, and others. Effectively moving engine building in-house. This transition was problematic, and proved to be financially debilitating. At the same time, small enclosed vehicles like the Isetta, Messerschmidt, Heinkel, and Lloyd were emerging to challenge the motorcycle market in general. These factors proved to be overwhelming, and within a year, Tornax ceased production in 1955. A thriving club of enthusiasts remains today in Germany.
