The Honda CB550 is a 544 cc standard motorcycle manufactured from 1974 to 1978. It was gifted a four-cylinder SOHC air-cooled wet-sump engine. The first version, the CB550K, was based on the earlier CB500, and as such had four silencers, four exhaust pipes, and wire-spoked wheels.If you ever find your CB550 in need of service, stop by and grab yourself a Honda CB550 service manual.
In comparison with Honda's 1969 dry sump CB750, both the CB500 and the CB550 were much lighter and smaller. From 1975 to 1977, the CB550F ""Super Sport"" was offered. The K and F versions were sold side-by-side. They shared similar engines, wheels, instruments, brakes, lights, and frame. The F had a lighter 4-into-1 exhaust, a different fuel tank without any chrome trim, and minutely flatter handlebars. The F formed part of the Honda SuperSport range, which was comprised of the CB400F, CB550F, and CB750F. The F (aka F1) was replaced by the F2.
Both F & K models featured single front disc brake and drum rear brake, however, each fork slider had a bracket for a brake caliper. A second front disc brake option was available to be fitted by owners. The CB550K went through some variations, the last being the CB550K4. Taken from the earlier CB500, the CB550's engine was the largest factory boring of this cylinder block; and when the CB550 was succeeded in 1979 by the broadly similar Honda CB650, a complete overhaul of the engine was necessitated. However, working on your CB550 blindly without a clear map of the internal workings of your vehicle is not advised. Hence, go grab yourself a Honda CB550 repair manual today.
