  2. Hondamatic 450 for touring?

    Miscellaneous Discussion
    Hi all! I've been really interested in a 1983 CM450A I found locally; does this bike have enough get up and go to sustain highway speeds (75-85mph) for extended periods? I've never ran an air-cooled bike before, so I'm not sure how hard it's pushed by riding hard. All of mine have been much...

    Hi everyone. A little over month ago I became the 3rd owner of a 1978 CB400A Hondamatic Hawk in Tahitian Red.

    Inside the unit there is a lense with N 1 2. This lense and its bezel are rattling around inside this sealed unit. It doesn't appear serviceable. Is it? Mine looks better than the rusty bits I've seen online so I'm considering a fix. Do you have one to swap or sell? PayPal ready! So...
