If you are looking at this ad, I probably don't have to tell you how rare this sidecover is. This model was made in one half of each model year 1968-1969. The right sidecover was interchangeable with either the CB or CL450 of these years. They didn't sell many, and I have only seen one in my lifetime of collecting bikes.
It is painted red, but it is faded and its paint has an area on the top crease that the paint is rubbed off. It has its hard to find stock decal and its rubber and metal mounting grommet intact.
