I installed a pair of Knight Design lowering pegs on my 2015 R1200R this evening. If you look at the photos you'll see I put a tape to the factory peg, and to the new Knight Design while the bike was up on the center stand to show the difference. The Knight lowers your foot about 1-5/8" which is a huge improvement for me in leg comfort. The interesting thing is, it only costs you 3/16" in ground clearance when leaned over! In truth you'll probable be grinding your boot before you hit peg because of the absence of the drag spur on the OEM peg.
I didn't have a chance to go for a ride after the install which took less than a half-hour, because I had to do a conversion from the BMW GPS mount to a Garmin 590LM mount that took a LOT longer.
I'm hoping the lack of a rubber pad doesn't make the engine vibration too bad on the Knight pegs. I'll check in after I've spent some time on them.
