Overview

Introducing the 1957 Horex Imperator The 1957 Horex Imperator is a captivating piece of motorcycle history that bridges the gap between classic design and robust engineering. Emerging from post-war Germany, Horex positioned itself as a manufacturer of innovative and reliable motorcycles, with the Imperator serving as a versatile allrounder. Sporting a sleek profile and a blend of functional aesthetics, this bike appeals to both enthusiasts and collectors who appreciate the craftsmanship and character of mid-20th-century motorcycles. The Imperator is not just a mode of transportation; it represents a nostalgic era of motorcycling where simplicity and elegance were paramount. Engine Performance and Riding Characteristics At the heart of the Horex Imperator lies a spirited 400cc single-cylinder, four-stroke engine that delivers a respectable 18.90 horsepower at a peak of 6790 RPM. This power output translates into a top speed of 135 km/h (83.9 mph), making it an agile companion for both city commutes and leisurely country rides. The engine's 7.5:1 compression ratio and air-cooled design ensure reliable performance, while the carburettor fuel system provides a straightforward and responsive throttle feel. Riders will appreciate the smooth torque delivery, allowing for easy acceleration and a satisfying ride experience. Despite its weight of 196 kg (432.1 lbs), the Imperator’s well-balanced structure gives it a nimble personality that belies its heft, making it a delight to maneuver through winding roads. Key Features and Technology The Horex Imperator is not just about raw power; it also boasts an array of thoughtful features that enhance both safety and convenience. The duplex cradle frame provides a sturdy foundation, while the 190 mm drum brakes at both the front and rear ensure reliable stopping power, a crucial factor for any rider. The bike’s dimensions, with a length of 2,140 mm and a width of 660 mm, contribute to a comfortable riding position that accommodates extended journeys. With a fuel capacity of 17 liters (4.49 gallons), the Imperator allows for longer rides without the constant need for refueling, making it a practical choice for touring enthusiasts. Its classic lines and vintage styling resonate with those who have a penchant for the aesthetic traditions of motorcycling. **
