Overview

Introducing the 1958 Harley-Davidson KR 750: a compelling blend of classic design, rugged performance, and American engineering that solidified Harley-Davidson’s reputation in the enduro-offroad category. As a model that emerged during the golden age of motorcycling, the KR 750 was not just a bike; it was a symbol of adventure and freedom, appealing to those who dared to take the road less traveled. With its robust build and distinctive styling, this motorcycle quickly became a favorite among enthusiasts and racers alike, setting the stage for the brand's legendary status in both dirt and street riding. At the heart of the KR 750 lies a powerful V2, four-stroke engine that displaces 744cc, delivering an impressive 46 horsepower at 6,500 RPM. This power enables the bike to reach a top speed of 110 mph, making it a formidable contender on any terrain. Riders will appreciate the smooth power delivery and responsive throttle, all while enjoying the distinctive throaty growl that only a Harley can produce. Coupled with a 4-speed gearbox, the KR 750 allows for an exhilarating ride, whether you're tearing through dirt trails or cruising on the pavement. The lightweight chassis, tipping the scales at 360 pounds, combined with a power-to-weight ratio of 0.2817 HP/kg, ensures that this bike feels nimble and agile, giving riders the confidence to tackle even the most challenging off-road conditions. The KR 750 boasts several key features that enhance both its performance and rider experience. The telescopic front suspension offers improved handling and stability on uneven surfaces, while the rigid rear suspension design pays homage to the simplicity and durability that Harley-Davidson is known for. On the technology front, the single Tillotson carburetor and Fairbanks-Morse magneto ignition system contribute to reliable performance, while air cooling keeps the engine running efficiently even in tough conditions. The bike's vintage aesthetics are complemented by a classic design that showcases Harley’s iconic branding, making it a true collector's item for motorcycle aficionados. **
