1978 model you can tell by the badge. Honda calls this color Candy Alpha red which looks like a deep shiny brown. Boy is it hard to take a picture without reflections. Beautiful, no cracks or broken tabs. This is as close to a New NOS sidecover as you can find. Just a couple of very minor rubs on the paint. The paint is a little more faded on the badge, however you would be proud to put this on a any bike. Should physically fit all CB550 Fours.
