Since you were kind enough to post photos of my 1976 Honda CB750 custom build that I recently finished I wanted to show you the trailer I built for it to tow behind our old GMC camper.
It could have turned out better if I really took my time but I got this as a stripped down old pop up and it needed a lot of fixing.
I added a new floor-raised and extended the front so there was a "Bib" to protect the bike from rock and debris while towing. Added brand new lights and wheel bearings and 3 new wheels -one for a spare. I basically used scrap metal and wood I had here at home to do this. I even made the fenders out of old plywood braced with metal.
Maybe it will give others some ideas when they need a trailer to haul things.
Thanks again and keep up the great site!....Nick
