The Honda CB550K "Four", introduced in 1974, replaced the CB500K. It was produced until 1978 with minor revisions each year.

The Honda CB550 is a motorcycle manufactured by Honda. It is considered the younger cousin to Honda's CB750 and was introduced in 1974 as the CB550K0. Later iterations were produced through 1978 ending with the K4. Furthermore, the CB550 was offered in a Super Sport, "F" model called, simply, the Honda CB550F. Cosmetically, the CB550 looks much like its larger and smaller cousins. Colors included Flake Sunrise Orange with Black, Boss Maroon Metallic with Black, Freedom Green Metallic with Black, Candy Jade Green, and Flake Sunrise Orange. Stock exhaust was a four-into-four style. Other options included a two-into-two style and a four-into-one on the Honda CB550F.

Specifications for the CB550 were virtually unchanged over the model lines.

Reviews

Reviewers were overwhelmingly positive in regards to the CB550 during the 1970s. However, in some aspects the CB550 is lacking; especially in terms of braking. Despite the reviewer's suggestion, the CB550 is not a beginner's bike. Power comes on suddenly and with lacking brakes, can make the CB550 unforgiving. Furthermore, the handling, when compared to modern sport bikes, is unresponsive with considerable head shake when riding aggressively through corners. However, the CB550 still garners respect.


Maintenance

Maintenance on the CB550 is nearly identical to the Honda CB750 and can be completed, mostly, with common hand tools. Some specialized tools, including feeler gauges, a timing light, chain breaker and riveter, amongst others. Common maintenance tasks include chain tensioning and cleaning/lubing, valve adjustment, rear brake adjustment, oil and filter changes, etc.

Overall, if common maintenance is performed regularly at the proper intervals with quality parts, the CB550 is very reliable and has been reported to be good for 100,000+ miles.
