1979 marked the end of GL1000 development with the K4 model (the UK version was designated KZ). Dry weight increased slightly to . for the last Gold Wing to be powered by a one-liter engine. There were only minor changes for this model year, except for the ComStar wheels; new ComStars had stronger steel spokes on aluminum rims instead of the original aluminum spoked wheels that precipitated a 1979 recall (for the 1978 model year). During the final run of the GL1000 in 1979, "Hondaline" saddlebags and trunk were available, but Honda still did not offer a fairing.
