Derived from the 1966 CB450, it stood out for its modern air-cooled inline four-cylinder engine, capable of reaching 200 km/h with a high degree of safety and reliability — a feat that none of the contemporary Italian manufacturers had managed to match. This combination of performance, innovation and ease of use immediately won over the demanding North American market, consolidating Honda’s reputation as a benchmark in the high-capacity motorcycle segment.
Among its technical innovations, the CB750 introduced a front disc brake — a first on mass-produced motorcycles — a five-speed gearbox, and an average fuel consumption of just 5 litres per 100 km. More than a motorcycle, it represented a technological leap that would mark the beginning of the “superbike” era.
The K2 version, launched in 1972 and now represented in the collection of the Caramulo Museum, retained the successful formula intact while adding aesthetic and practical refinements: a gold pinstripe on the fuel tank, smaller side logos, a larger rear light unit and enlarged reflectors, enhancing safety.
The overall package preserved the innovative spirit of the original model, establishing itself as a historic milestone in motorcycle engineering and one of the most sought-after examples of its generation.
