Very unique and beautiful crash bar arrangement.
Taken from a 1974 CB450 Honda. However its 1974 model code is 346 which is the same for all CB450 Hondas from 1972 to 1974 Would likely also fit 1971-1973 as their frames were very similar. It has a main bar and two footpegs with rubber cover. but also two other side protecting bars included. Very good condition, chrome is very good all around.
dimensions 72 cm wide, 37 cm tall, 19.5 cm I.D. between bottom mountings top mount holes 4.3cm on center
