A Brief History of the Marque

Tornax, Wuppertal

Manufactured: 1926-1955

Tornax was founded by Ernst Wewer and a Mr. Schmidtmann in 1922. The firm contracted with J. A. Prestwich for the supply of engines and production began in 1926 with the 600cc model I-26. In 1930 they released the then fastest road-going motorcycle the world had seen, the Tornax 1000. The company had considerable success in competition during this period.

As the financial crisis deepened, in 1931 or '32 the big V-twin was discontinued and the firm began producing lighter machines of 125 and 250cc using JLO engines.

In the 1950s the Tornax Schwarze Josephine (Black Josephine) powered by a JLO 250 twin proved a very successful model.

During this period Wewer bought the rights to the Opti 4-stroke twin and cancelled the contract with Jlo. Unfortunately, the Opti proved a disaster and contributed to serious financial problems.

Over the years Tornax used many different engines including JAP, JLO, Bark two-strokes and Columbus.

They also built an automobile, the Tornax Rex, powered by a 700cc DKW two-stroke twin.

There is a very good history of the marque at

In the 1920s components were supplied by a number of manufacturers. Forks from Tiger-Werken in Cologne, fuel tanks from Spillner of Cologne, brakes from Pränafa in Solingen, and gearboxes from Hermes-Getriebebau of Wuppertal and from Burman in Britain.

Hello! I'm Dieter from Wuppertal in germany where Tornax-Motorcycles were manufactured. I created the biggest Tornax-homepage in the world:
I search any info about Tornax-Bikes in the world, which countries did they reach? I need also every brochure and other things. Do you have a nice story how you received your Tornax?
I am working at the first Tornax-Book, it will be published in 2009! Thanks to all. Nice greetings. Dieter

Hello, I'm Giuseppe from Italy
I would like, if it is possible, you to open the Tornax page, so I'm sending to you all the information I was able to find about Tornax : " Tornax from 1950 to 1954 built different types of light motorbikes, with two times engines, of 122, 173, 197, 244 and 247 cc with two or free gears, and with conventional frames. Tornax built also a racing car, in 1951, of 125 cc, planned by Ing. Kuchen." I'm sending also a picture of my Tornax motorbike, it should be a LM 200 of '52.
Thanks for the attention, -- Giuseppe -- defer at
