Home made Farkles-Like a lot !!!
Exile, WOW, I really like your style. Making your own farkles! Cool.
I've made a few for my 2006 DR650... like a package shelf on the left side, attached to the left rear foot peg mounting bolts. It will hold a case of beer or a plastic fuel jug. Probably more things too.
Made a bracket for the right side of the bike that bolts to the right rear turn signal mount bolt and the right passenger foot peg mounting bolts. I bolt on my Kolpin rifle case or the home made chainsaw bar sheath that holds the 20" bar and Stihl 031 saw (1978 model-got new). Works well for opening logs on trails.
Think your rack and pannier frames are cool, and will be doing some copying, if you don't mind.
