Adler Founded by Heinrich Kleyer in 1986 as the Adler Fahradwerke AG to produce bicycles and in 1895 started manufacture of typewriters. In 1896 they made their first car and in 1902 motorcycle production started, but only lasted a short time until 1907. It was then after the WWII that they went back to motorcycles in 1949 when they produced the first 100cc machine. They continued with a broad range of machines until 1957 and in July of 1958 with slumping sales Grundig gained a majority share in the company. The senior management were then instructed to concentrate on typewriter production and the motorcycles came to an end.

Adler Model Reviews

MB100 1949-56, 98cc, 2 stroke, 3 speed, 3.7bhp, 44mph A nice commuter bike which was formed around a twin duplex frame which had both front and rear suspension. The front was a complex leading link design attached to an internal coil spring with oil damping and the rear using plungers. The fuel tank held 7 litres which gave this bike a good range. MB125 1951-56, 123cc, 2 stroke, 3 speed, 6.8bhp, 55mph Of similar design to it's smaller brother the MB100 but with a larger 12 litre tank. The brakes were beefed up using a full width 150mm drum. MB150 1951-56, 147cc, 2 stroke, 4 speed, 59mph Similar to the MB125 but substantially larger bike altogether. Available in Black or Metallic Grey MB200 1951-56, 195cc, 2 stroke twin, 4 speed, 63mph Very much the same as the MB150 but with a larger capacity engine. All the cycle parts were common to both models, although the MB200 was 10Kg heavier. This gave it a marginal improved top speed, but the acceleration was markedly better. MB250 1952-55, 247cc, 2 stroke twin, 4 speed, 74mph Similar to its baby brother the MB200 but with a larger 180mm drum brake up front, a different paint job on the tank and fish-tail silencers. This was by far the best selling model of the marque. The twin two-stroke piston ported engine sported a square 54mm bore x 54mm stroke, which was to set standards for future manufactures breaking new ground and providing the pathway to higher revving machines. MB250S 1954, 247cc, 2 stroke twin, 4 speed, 77mph, 70mpg High level exhaust pipes give this sports model a speedy look and there was a small increase in power from 16bhp to 18bhp. There minor changes to the range in 1953 especially around the electrical systems and tank sizes, and changes to the front suspension on all models in 1954. With declining sales in 1955 Adler introduced the Junior which was a 98cc scooter. Sprinter 1956, 247cc, 2 stroke twin, 4 speed, 80mph The new model had a tuned MB250S engine and a new frame sporting swinging arm rear suspension. Favorit 1957-58, 247cc, 2 stroke twin, 4 speed, 74mph Replacing the MB250 it had the same specification only with a single foam seat. For 1957 Adler ditch all the older models and went forward with the Junior scooter and the Favorit motorcycle.
