I ran across a local ad for a trike kit for a 650 for $525, including instructions and video(s). Out of curiosity (I have a 400) I called the guy and asked if he was on BUSA and he said no. He said it is a Tow Pack. He has installed a couple of these on Burgmans including this one, which he more recently removed for the owner because he couldn't ride any more. I don't know but, thought it sounded sounded like a deal and wanted to pass it on to y'all. I presume he would sell it for the asking price plus shipping. I haven't seen it, didn't ask its condition or what years it would fit. PM me for his phone number if interested.
