Overview

Introducing the 1956 Horex Imperator, a classic motorcycle that effortlessly embodies the spirit of post-war German engineering and style. Positioned in the all-rounder category, the Imperator was designed to cater to a diverse range of riders, from urban commuters to weekend adventurers. With its sleek lines and robust build, this motorcycle not only turned heads but also established Horex as a serious contender in the competitive motorcycle market of the 1950s. The Imperator was a testament to Horex's commitment to quality, combining aesthetic appeal with functional performance, making it a beloved choice for enthusiasts and collectors alike. At the heart of the Imperator lies a single-cylinder, four-stroke engine with a displacement of 400cc, generating an impressive 18.9 horsepower at 6,790 RPM. This power allows the motorcycle to reach a top speed of 135 km/h (83.9 mph), providing a thrilling ride for its era. The engine’s design, featuring a 7.5:1 compression ratio and air-cooled system, offers excellent reliability while maintaining a smooth power delivery. Riders will appreciate the responsive nature of the motorcycle, which is further enhanced by its chain final drive. The combination of a light yet sturdy frame and a balanced weight of 196 kg (432.1 pounds) ensures that the Imperator handles confidently, making it a joy to navigate through winding roads or city streets. The Horex Imperator is not just about performance; it also boasts several key features that elevate the riding experience. Its duplex cradle frame provides structural integrity and stability, while the expanding drum brakes—both front and rear, measuring 190 mm—offer dependable stopping power. With a fuel capacity of 17 liters (4.49 gallons), riders can embark on longer journeys without frequent refueling stops, enhancing its practicality for both daily use and longer excursions. The motorcycle's dimensions, with a length of 2,140 mm (84.3 inches) and a width of 660 mm (26.0 inches), contribute to its manageable handling, striking a balance between comfort and control. **

Pros

  • Classic Styling: The Horex Imperator features timeless aesthetics that appeal to vintage motorcycle enthusiasts and collectors.
  • Reliable Performance: With its robust 400cc engine and sturdy construction, the Imperator offers a dependable and engaging riding experience.
  • Comfortable Ride: The well-designed chassis and balanced weight allow for smooth handling and increased rider confidence.

Cons

  • Limited Power: While 18.9 HP is sufficient for leisurely rides, it may feel underpowered compared to modern motorcycles, especially for highway cruising.
  • Drum Brakes: The expanding drum brakes, while reliable for their time, may not provide the stopping power and responsiveness expected by today's standards.
  • Weight Considerations: At 196 kg (432.1 pounds), some riders may find the Imperator on the heavier side, which could affect maneuverability for less experienced motorcyclists.
