I haven't really seen much aftermarket for this. At the beginning of the year I was going to take my bike down to Orange County Choppers to have them FAB some stuff up, and someone mentioned to try and get some levers made up. Never happened though as there wasn't enough interest. With that said, the only ones I have found (for the shifter anyway) are pretty much like a stock dirtbike one where the end can bend around. If you know someone w/ a metal shop they could probably weld a piece on for you or something I would imagine. I have size 13 feet that are pretty wide, and don't really have this issue on anything.
