Here is a set of wheels from a CB500K four. This was an unfinished project.
The wheels have been powder coated, new spokes, appears to be new bearings. There is no brake shoes in the rear wheel. This is just how I got them.
They are a little dusty. These can be used on the CB500K, CB550K, or CB550F models up to 1976. The rear sprocket is for the 500. So you may want to change it if you are putting these on a 550.
