Down side to this thing is the fact that you are bolting a piece of welded together steel, that has no engineering data to support it's strength, to a piece of 1/2" plywood (in most motorcycle trailers), maybe tieing it into one crossbar made of 1/4 angle iron welded onto the frame of the trailer if the install location happens to match up with the crossmember.
Personally I do not want to tie down a 900# + motorcycle with a bracket held in by 4 bolts to a piece of plywood. Wouldn't take much impact to rip the whole thing from the floor. A strong man can beat a hole in a piece of plywood with a 16 oz hammer, so what happens when you add the other 899#s?
And before anyone comments that all trailers have motorcycle tied to plywood floor, well mine doesn't. I have e-track welded front to back on both sides of trailer to each crossmember as well as the front and rear of the trailer and a Condor thru bolted to add-in crossmembers.
I take this strength thing serious.
