Taken from a 1972 CB450 .Very nice shape, chrome is very good on top with only very minor rust areas at the underneath welds Backrest has a repaired area underneath and is slightly canted. 1972 CB450 had a product code of 346 shared with 1973 and 1974. However I believe it will also fit K-2 K-4 as the rear ends are nearly the same. Email me if you have fitment questions for your model before ordering More photos coming
