I did this/do this with the BD hitch and modifications I put into the
archives years ago. I run a Honda XL500S comfortably on a motorcycle rack
that goes on a receiver hitch that I had made up to bolt on the BD hitch
plate. Also use a hitch mount for four bicycles if I'm not carrying the
motorcycle. My reserve gas can in the spare tire well provides the juice for
the Honda on a long wilderness stit. Added about 10 psi to the rear when
carrying the motorcycle. The motorcycle carrier includes the ramp. Works like
a champ. Seriously reduces tailgating!
