To me that sounds a bit long to be pulling behind a motorcycle to me. I would think it could cause lots of sway.
The longest trailers made for motorcycles (that I have seen) are the pop up campers and even with tongue they are only 110 to 115 inches.
Thanks for the input, Lucky. I hadn't thought about sway. I have no experience pulling trailers with a motorcycle so thought I would put the question out there. Sounds like it would be a bad idea. I thought it would be kind of fun to show up at a lake or beach on a motorcycle with my kayak. Nice ride there, nice paddle around, and nice ride home. Just a fantacy.
