Beautiful bright chrome seat rail taken from a Honda CB350 Four cylinder. The chrome on this piece makes it look like it could be NOS. A thin small piece has been broken off(possibly a bungee cord mount??) from one side-- The broken piece is included and it could be welded back on.
26.4 cm inside shock mounts
