Honda CB550 & CB500K Model Overview & History

The Honda mid-sized four-cylinder lineage began in 1971 with the 498cc CB500 K0, followed by the K1 (1972) and K2 (1973). In 1974, the engine was bored out to 544cc, marking the birth of the CB550K series. Performance enthusiasts recognize the CB550F Super Sport (1975-1977) for its signature 4-into-1 exhaust system. The series concluded with the CB550K3 (1977) and CB550K4 (1978), which featured updated carburetors, fuel tanks, and styling trim.

Compatibility Note: These engine and fuel system components are specifically for 4-cylinder SOHC models. They are NOT compatible with the Honda CB500T (1975-1976 Twin Cylinder), though some suspension and braking components may overlap.
