This is a home built mono-wheel (single wheel) motorcycle trailer. To make this work for your motorcycle you would need to have a trailer hitch with a vertical flat surface to mount the Universal Joint to. It needs to be a good solid mounting point, and you are good to go. If you have a ball hitch on your bike now, you can fashion up a T-Plate to bolt under the ball hitch and use the "top" of the Tee to bolt this to.
It is very lite weighing in at only 64 Lbs. and will carry quite a bit of camping or hotel gear. It used to carry 2 each ~ (sleeping bags, air mattresses, collapsible chairs, tent and gear)
The parts here are worth well over $500 to build yourself (Thule would be $400, axel & tire well over $100 plus all the nuts & bolts!)
It has a speed rated tire and axel for highway use.
It does have a functioning trailer light which has turn signals and a brake light (4 pin).
I never did have it licensed and never had a problem.
No, it does not have a suspension and does not need one, just don't go hauling around your fine China and you're fine...
