Interesting. Let us know how it turns out, please.
I, too have a SW Motech centerstand, also ordered from Twisted Throttle (whose excellent customer service is a rare and fine thing). Had it on my 919 for 2 years when it started behaving...oddly.
At first I thought my chain, which only had 12k miles on it and was maintained carefully, was reaching the end of its life and stretching. Tightened it up a couple of times, then replaced chain and sprox. Then the new chain started contacting the centerstand as well...about the same time that the bike started to become harder and harder to get off the centerstand. Uh-oh. I got down on the ground and took a look, and sure enough, the mounting bosses of the stand were bending where they contacted the holes in the frame. I pulled off the stand, with help, sent photos to Twisted Throttle, and they had a new stand on the way shortly.
Good outcome, for me, but sounds like SW Motech's QA is a bit off. Maybe you got a lemon of a stand...1.5 inches off the ground at the rear wheel? Too much.
Photos of my bent stand:
Not sure if welds cracked before or during removal, but alarming:
Hopefully the replacement will hold up better. I'll be checking it regularly.
