With its sleek lines and robust build, this bike not only captures the eye but also promises a dependable ride, making it a favorite among enthusiasts who appreciate classic motorcycles with a storied past. At the heart of the Adler M 250 S lies a spirited 247cc twin-cylinder, two-stroke engine that delivers a thrilling performance.

Equipped with drum brakes at both ends, measuring 180mm, the M 250 S delivers reliable stopping power, instilling confidence in the rider. The rear suspension, featuring two shocks, absorbs bumps effectively, making for a comfortable ride on various terrains.
