Manufactured by Dorko-Werke, Abt. Motorenbau, Jäckstrasse 4, Bamberg, 1924-1926
Dorko-Werke purchased Juhö after it closed and built the same 195cc machine, later adding a 269cc 2½ h.p. four-stroke with three-speed gearbox, kick starter and clutch. These motorcycles were marketed as Juhö and later under their own brand, the 350cc Hamakraft "Hexe" (Witch) powered by an S.u.G. engine.
The owners were S. Dorn and J. Kahn, later Dorn, Krüger & Co. The company had 50 employees and an extensive range of products. They converted military vehicles for civil use, and built electric drills. Half of the workforce was laid off during the inflation period before their bankruptcy and closure in 1927.
