Finally made a bit of progress.
GSXR shock is here and drilled out to fit the Ninja.
After much consideration I went with eBay / made in China rear sets, Sato copy. To mitigate spares shipping delay I got 2 sets, so one full rear set will go into the spares bin.

Still need to resolve the clip-ons question, actually considering a set from eBay as well. With rear sets there were many reviews on quality, so I felt ok getting them, but can't find much on clip-ons. Any thoughts? (looking for some actual experiences rather than "boo made in china sux boo".
Edit: at least one data point that says eBay clip ons are fine
