I initially purchased my B with the Engine Protection Bar and the BMW "Webber Grill Master" Leg Rest; I tried using the Leg Rest on a few rides, it wasn't a comfortable position for me. Similar to Kickstand_Down, I find the floorboards extremely comfortable when compared my GS Adventure bike, and I didn't want to take away from the look of the bike - so I sold the BMW Leg Rest. I've even considered removing & selling the BMW engine protection bar, in order to restore the look of the bike; however, I need the Protection Bar to mount the TC Lower Leg Wind Protection pieces.
I may go out and dork around on the B model, while I'm out in the garage later today (
Installing upper protection bars on cousin's Triumph Tiger XRT 1200), just to re-visit the Leg Rest thing... If I was going to attempt a Leg Rest; I'd probably would go this route as the BMW OEM rest didn't work out.
Below shows how the Leg Rest mounts over the cylinder heads - again, solid Wunderlich design:
