1954 Adler MB 250

The success of the modern twin-cylinder 2-stroke, such as the Yamaha RD series, can be traced back to the postwar Adler. The MB 250 was a revolutionary design that set new standards, and was copied by many manufacturers such as Ariel and Suzuki, not forgetting Yamaha. Adler also built typewriters, and when motorcycle sales in Europe declined they were purchased by Grundig who still produced them under the TA label. Adler translates to Eagle in English.
