When you acquire a CB
Four, the best you can do, is to first determine your exact model by comparing engine- and framenumber to those listed in the first few pages of the Parts Lists. Honda does NOT determine models by year; that is an American invention. There are quite a few differences between models exported to the various markets. You can trace them at CMSNL ofcourse, but
only the parts list will offer you the
overview that fiches lack. It is nice to know what other markets had, so you can pick whatever you like best. For instance, some folks prefer the modest indicators only the
-G models had. Personally I dislike amber plastic and always wanted to get rid of the plastic side reflectors. In the parts list of the CB500K2 (ED, G, F) I detected that the
-F model, for France, originally had modest crossheads instead of the showy reflectors. I've ordered these screws at CMSNL, so my model now is a mix of the CB500K2-ED and the CB500K2-F
. As far as your model, you may notice that the CB550K3
-ED had a 34 teeth rear sprocket, where the others had 37. This was for marketing reasons: the somewhat sportier CB550F2 was launched at the same time and Honda wanted to highlight the K3 as the
tourer version.
