The sportsbike that started it all

The Honda CB400F, or the 400/4 as it’s more commonly known, was introduced in 1975 as a refinement of the CB350. It had a bigger engine, a six-speed gearbox, and a cool chromed 4-into-1 exhaust system. This defined its aesthetic appeal, embracing the European ‘cafe racer’ style with low handlebars and rearset footrests.

Despite its modest engine size, it earned a reputation for exceptional riding enjoyment. It quickly became a cherished classic and an important model in Honda’s history. It was made from 1975 to 1977 and came in two models, the F and F2. They had different designs and features, like paint colours, logos, and pillion footrest mounts. It’s a beloved and sought-after bike among collectors and enthusiasts today.

Honda’s CB400F may have only been around for three years, but it played a huge role in shaping the world of motorcycles. As Japan’s first true sportbike, the 1975 CB400F Super Sport was the first Japanese motorcycle to combine modern sporty design and performance.

Despite its fewer horsepower compared to rival two-strokes, the CB400F offered superior refinement, smoothness, and fuel efficiency, aided by its six-speed transmission. This model also found success in club racing, with racers like Kaz Yoshima boosting its performance and solidifying its reputation as a formidable contender on the track.
