Segment: Clasic

The 1955 Adler MB 250 is a middle-weight machine suitable for daily commuting inside the urban jungle.

It boasts superior comfort levels (for it's time), thanks to a high-end suspension package, composed of a leading link fork, and twin plunger shocks. It also sports an air-cooled, two-stroke, 247cc, twin cylinder powerplant paired to a four-speed manual transmission, and can produce a claimed 16 horsepower at 5600 rpm.
