Overview

Introducing the 1957 DKW Hummel, a charming piece of motorcycle history that perfectly encapsulates the spirit of post-war German engineering. As a sport motorcycle, the Hummel was designed to appeal to youthful riders seeking an agile, lightweight machine that offered a blend of excitement and accessibility. With its modest price point, the Hummel became a popular choice among those looking to dip their toes into the world of motorcycling without overwhelming financial commitment. This delightful two-stroke machine is not only a prime example of DKW's innovative spirit but also a nostalgic reminder of the simple joys of riding. At the heart of the Hummel lies a spirited 49cc single-cylinder two-stroke engine, capable of reaching a top speed of 40 km/h (24.9 mph). While it may not break any speed records, the Hummel’s lightweight construction and responsive throttle provide a surprisingly lively ride. The air-cooled engine, equipped with a Bing carburettor, delivers a characteristically peppy performance ideal for zipping around town or taking on twisty backroads. The 1.3:1 compression ratio ensures that every ounce of power is harnessed efficiently, while the chain final drive transfers that power to the rear wheel, allowing for smooth acceleration and a connected feel between rider and machine. The Hummel’s design features a pressed steel frame that balances durability with lightweight agility, making it an approachable motorcycle for novice riders. Its suspension system, highlighted by a swingarm rear, enhances comfort and stability, allowing riders to tackle uneven surfaces with confidence. The expanding drum brakes at both the front and rear provide reliable stopping power, ensuring that safety is not compromised in this spirited little machine. With its minimalist yet functional design, the Hummel reflects the simplicity of its era while incorporating the technological advancements of its time. In summary, the 1957 DKW Hummel is more than just a motorcycle; it's a delightful journey back to a time when simplicity and fun were at the forefront of two-wheeled adventures. Whether you're a seasoned collector or a newcomer to the world of motorcycles, the Hummel offers an engaging experience that celebrates the essence of riding.
