but I have heard and seen several that towed 2000 - 4000 Lb. boats... so that would equate to 200-400 Lb tounge weight. the hitch MUST be installed to handle the load, but I don't see any trouble towing a 250Lb motorcycle on a small utility trailer.
do a search with the words 123 and hitch on this forum and I bet you find plenty of info on it.
