Always preferred the heel/toe shifter. Bought the Kury for my 2016 F6BD. Works very well with no issues. I still have driver pegs (always have had footboards but these pegs are surprisingly comfortable and a nice change). No install conflicts with foot pegs, side stand, et.al. as mentioned earlier.
I just bought the shifter and break lever for the other side. I like a larger break pedal. No problems so far but I don’t stomp on the upshift. I just apply enough pressure to get into gear. Before I would occasionally miss shifts because my boot was pushing up on the shifter constantly.
