Taken from a 1971 CB500K1. Fits 1971-73 CB500 K0-K1-K-2 models. Excellent chrome, straight no dents, no rust check out the pictures. Correct mounting struts and turn indicator brackets are shown. This rack is not compatible with later CB550 models without modification due the difference in tailights. If you want a backrest, I have the one that came off this one for sale under a separate sku5698
