CB550F/K (74-78)

Sharing many qualities with the CB550K, the CB550F had some definitive differentiators from the line-up. It was the largest factory boring of the smaller block, air-cooled, 4 cylinder, single over-head cam motorcycles made by Honda during the mid- to late 1970s. The block of the CB550 was similar in appearance to, but considerably smaller than, the heavier casting of the CB750. These motorcycles had two stock gauge and exhaust configurations. The early models had a single gauge cluster and four individual exhaust tubes, each with its own muffling elements. The "Super Sport" model, featured a dual gauge cluster (with a separate speedometer and tachometer) and a stock 4-into-1 header. CB550s shared a similar emblem to the other "Fours" made by Honda: the triangular side covers had the upward-rounded displacement (550, in this case) with the word "Four" superimposed. With the stock gearing, the CB550F Super Sport was capable of reaching speeds in excess of 105 mph (169 km/h) with a 200 lb (91 kg) rider, while remaining well below the 9200rpm yellow line limit on the gauges. Combine that with the engine configuration, placement in the frame, and the fact that it redlines at 11,000rpm and you've got one choice machine for racing the juke box on a Saturday night.
