HONDA produced two types of CB550 models:  the CB550f and the CB550K3. The CB550f was known for the 4 into 1 exhaust on the right hand side. The CB550K3 was provided with the classic 4 into 4 exhaust. The CB550K3 model would have the choke-control on the dashboard, whilst the F models were operated on the carbs using a lever.

The first CB550F release was the CB550F1 model (1976), its predecessor was the CB550F2 model (1977-78).
