I've seen the basic motorcycle rail for sport bikes and dirt bikes, but that hydrualic one is interesting. I can tell you that the weight of my Dyna exceeds the tongue weight rating for my trailer hitch, let alone the additional weight of that thing. Probably a good idea for the Class A motorhome, but not going to work on my 1/2 ton pickup.

 

I have had one for years. I still use it and it is great.
You just need to be aware that the weight on back will probably cause too light of Tongue weight and you might need to add weight to front of trailer so the trailer doesn't start to fishtail, and I use a strap to keep the lift from wobbling side to side.
