I'm 6'8" tall and ride a 2012 Super Tenere, and I regret missing most of this conversation.
I use the SW Motech Ion pegs and I like them a lot. I've searched high and low for years and have not found an option that will get the pegs any lower. I believe the Ion mounting kit for Gen 1 XT1200Z was discontinued a few years ago, so they may be hard to find but it seems there is still support for 2016+. I'll be surprised if that kit is any different from the kit for older 1200's.
One thing to note about the Knight pegs - I think the 32mm drop they publish is a bit misleading. I ordered the "Wide, Front, Lowered 1-1/4 inches" with "Trakker tread" and when I received them it was apparent that the drop was about the same as with the SW Motech Evo pegs. If you run the Motech Evo without the optional rubber top pad then you get the same drop as with the Knight with Trakker or Hunter tread. There may be other reasons to choose the Knight pegs, and there may be more of a distinction if you compare both brands with the rubber treads installed.
My biggest issue is that my bike is street-parked in Brooklyn, NY and it's been laid down about ten times over the years thanks to careless parallel parking neighbors. The pegs are the first thing to contact the street, and I don't think they're folding the way they were designed to do (or perhaps they were not designed to fold if the bike is not moving forward when dropped). The steel frame is bent on both sides where the pegs mount. Shops don't want to try to bend it back because it's a lot of labor for something that might not work out, and they're afraid of doing more harm to the frame. I think it's a huge miss from Yamaha having the pegs mounted directly to the frame in this way.
