In My Humble Opinion, not having ever put a bike on the rear of a trailer, I would think that it would mess up the pin weight, cause frame flex, twist, and just generally create problems. The frame on our Monty's is not that heavy and is of soft steel. I just added extra stabilizers in back of the wheels, and the steel was very easy to drill through for the brackets.
I rode Gold Wings for about 15 years, and they weigh 880 pounds, stock.
I sure wouldn't want something like that hanging on the rear end of my trailer. A fat boy I believe wieghs in the neighborhood of 600 pounds wet. A lot of wight no matter where you go. There is also degree of moment imparted to the trailer, and the weight bouncing around back there.
Again, this is just my opinion. If you can get it to work, YES!!!!!
Motorcycles are aobut the best thing man ever invented other than aircraft.
