Compared to Honda's 1969 dry sumpCB750, both the CB500 and the CB550 were much smaller and lighter. The CB550K shared some visual similarities with the CB750, and it fitted into Honda's four-cylinder range as its mid-capacity bike.
From 1975 to 1977, a second version of the CB550 was offered, the CB550F "Super Sport".[1] The CB550K and CB550F were sold alongside each other, sharing a similar engine, instruments, lights, wheels, brakes, and frame. The CB550F has a lighter four-into-one exhaust, slightly flatter handlebars, and a different fuel tank without chrome trim. The CB550F is part of the Honda Super Sport range, along with the CB400F, an CB750F. The F (aka F1) was succeeded by the F2, which had an additional flash decal on the fuel tank and deletion of the fork gaiters.
Both CB550F and CB550K models had a drum rear brake and a single front disc brake, although each fork slider had a bracket for a brake caliper. The CB550K went through some minor iterations, the last being the CB550K4. Closely derived from the earlier CB500, the CB550's engine was the largest factory boring of this cylinder block; and when the CB550 was replaced in 1979 by the broadly similar Honda CB650, a completely new engine design was necessary.
Cycle Test magazine recorded a Шаблон:Cvt time of 14.47 seconds at Шаблон:Cvt in a September 1975 test of the CB550F Super Sport.[2] The engine output was Шаблон:Cvt at 8,000 rpm and Шаблон:Cvt torque at 7,500 rpm, with a curb weight of Шаблон:Cvt and average fuel consumption of Шаблон:Cvt.[2]
