Overview

### 1928 DKW ZSW 500: A Classic Sportbike Ahead of Its Time The 1928 DKW ZSW 500 stands as a remarkable testament to early motorcycle engineering, blending innovative design with spirited performance. Hailing from the German manufacturer DKW, this sport motorcycle emerged in an era when speed and agility were becoming paramount to the riding experience. With the ZSW 500, DKW positioned itself as a serious contender in the sport category, appealing to enthusiasts who craved both performance and style on the open road. As one of the pioneering models of its time, the ZSW 500 aimed to deliver a thrilling ride, setting a standard for future motorcycles. At the heart of the ZSW 500 lies a robust twin-cylinder, two-stroke engine with a displacement of 493.90 ccm. Generating a respectable 14 horsepower, this engine allows the motorcycle to reach an impressive top speed of 100 km/h (62.1 mph)—a remarkable feat for the late 1920s. The 68 mm bore and stroke deliver a balanced performance, ensuring a nimble ride that is responsive to the rider's input. The liquid cooling system aids in maintaining optimal engine temperatures, allowing for extended rides without the worry of overheating. Riders will appreciate the smooth acceleration and the engaging sound of the two-stroke engine, which creates a connection between the machine and the rider that is often lacking in modern motorcycles. The ZSW 500 isn't just about raw power; it also showcases key features that reflect the technology of its time. With a lightweight frame weighing in at just 135 kg (297.6 lbs), the ZSW 500 boasts an impressive power-to-weight ratio of 0.1037 HP/kg, making it agile and easy to maneuver through twisting roads or urban landscapes. The motorcycle is equipped with expanding drum brakes at both the front and rear, providing adequate stopping power for spirited rides. Although the rear suspension is non-existent, the ZSW 500's design allows for a connected feel to the road, giving riders a sense of control that is often celebrated in vintage bikes. ####
