Overview

Introducing the 1956 Adler M 100, a charming specimen from the golden era of motorcycle manufacturing that exudes both character and performance. As a sport model in Adler's lineup, the M 100 was designed to cater to riders seeking an exhilarating yet accessible ride. This lightweight motorcycle, weighing in at a mere 70 kg (154.3 pounds), offered a unique blend of agility and speed, making it a delightful choice for both enthusiasts and those new to motorcycling. With its classic styling and robust engineering, the M 100 holds a special place in the hearts of vintage motorcycle collectors and riders alike. At the heart of the Adler M 100 lies a lively single-cylinder, two-stroke engine with a displacement of 100 cc (6.10 cubic inches) that churns out a top speed of 70 km/h (43.5 mph). The engine’s well-balanced bore and stroke of 50 mm each, combined with a compression ratio of 7.2:1, deliver a spirited performance that’s both fun and engaging. The air-cooled powerplant is paired with a 3-speed gearbox, allowing riders to take full advantage of the bike's lightweight construction and nimble handling. Whether darting through city streets or enjoying a weekend ride along scenic country roads, the M 100 promises a responsive and exhilarating experience. The Adler M 100 isn't just about performance; it also showcases an array of thoughtful features that enhance its usability and rider experience. The double cradle frame provides stability, while the expanding drum brakes—both front and rear with a diameter of 125 mm (4.9 inches)—offer reliable stopping power. The carburettor fuel system ensures a smooth throttle response, and with a fuel capacity of 7 liters (1.85 gallons), riders can enjoy longer journeys without frequent stops. The kick starter adds a nostalgic touch, emphasizing the mechanical simplicity that defines this classic machine. In summary, the 1956 Adler M 100 is a delightful blend of nostalgia and performance, offering riders a unique experience that celebrates the spirit of motorcycling in its purest form.
