It's round bar that was formed in the profile of the floorboard and angled out a little, it's used to keep my prosthetic from sliding off. Yes the controls were modified; a linkage system and a left side brake pedal were added so that I can use my left foot to shift and brake. Both were fabricated and installed by Maxwell Brothers Cycle Shop near Petoskey, MI. They are a good group of guys at that shop that make sure that any mod's are done to meet your expectations and needs.Redwhat do you have around the footboards? have you controls been modded and if so by who?
