Overview

### Introducing the 1952 Adler M 250: A Classic Custom Cruiser The 1952 Adler M 250 stands as a testament to post-war innovation in the motorcycle realm, perfectly blending nostalgic charm with practical functionality. Positioned within the custom-cruiser category, this motorcycle beckons enthusiasts who appreciate classic design and the thrill of open roads. With its unique styling and robust build, the M 250 captures the essence of mid-20th century motorcycling, appealing not only to collectors but also to anyone seeking a stylish ride for leisurely jaunts. ### Engine Performance and Riding Characteristics At the heart of the Adler M 250 lies a spirited twin-cylinder, two-stroke engine that displaces 250 cc, delivering an engaging 16 HP at 5,590 RPM. This power is managed via a smooth 4-speed gearbox, allowing riders to harness the motorcycle’s capability while enjoying a balanced ride. The air-cooled engine, paired with a carburettor fuel system, delivers a satisfying performance that truly shines during relaxed cruising and gentle acceleration. The M 250 maintains a respectable fuel consumption rate of 5.70 litres per 100 km, making it an economical option for those long, winding rides. Weighing in at just 135 kg, its power-to-weight ratio of 0.1185 HP/kg ensures that every twist of the throttle translates into an exhilarating experience. ### Key Features and Technology The Adler M 250 is not just about engine performance; it also boasts several features that enhance both comfort and safety. The semi double cradle frame provides a sturdy foundation while contributing to the bike's agile handling. Equipped with 180 mm expanding drum brakes at both the front and rear, the M 250 ensures reliable stopping power, even in challenging conditions. The classic kick starter adds a layer of authenticity to the experience, allowing riders to engage with their machine in a way that modern electric starters simply can’t replicate. With a fuel capacity of 12 litres, riders can confidently embark on longer journeys without the constant worry of refueling. ###
