There’s not many ads I can find out there for the CB400F. Here’s everything, everything I could find. Thanks to Honda 4 Fun, SOHC4.net, and Ebay
I found these Honda CB400F photos here while looking around on google. I love finding stuff like this!
An awesome illustration showing the proper decal positioning on the Honda CB400F gas tank and side covers. Found here on this SOHC 4 forum.
