I have a very custom 2003 Harley Fat Boy that I wanted to mount some Heritage bags on. I quickly discovered that there was not an easy way to do this without drilling or modifying. So I designed a mounting system that allows the owner to easily add the Heritage bags by using my adapter brackets. The upper and lower brackets are CNC machined from aircraft grade aluminum and are attached using stainless steel hardware. This bracket system can be adapted to work with either the removable docking a fixed backrest or without a backrest. The photo shows a lower bracket also. NOTE: The rear turn signals will need to be relocated and this system will not fit a bike with the stock exhaust. Pipes must be at or below rear axle. Any Interest? I will try to attach photos of the brackets as the are hidden when installed.
