The CB200 forks are shorter by a few inches then the CB125t tubes so I just swapped them and they fit quite well. I would look at a fork chart and figure out what will fit Diameter wise and then start looking at the fork lengths. you should find something that will fit. Getting the tube retreaded might be a pain in the ass. Here is a list of bikes with 33 mm forks and Tube diameters as well as some other info.
