On my Tenere I used a shim pack, springs and valves from Cogent. And I've replaced seals and bushings(slides) in several different Japanese bikes for friends.
I've always removed the forks and disassembled them. Had to buy a few specialty tools, I now have a "fork" drawer in my toolbox. Unless it's a recently serviced fork, I replace the bushings and seals. Draining is easy, turn the fork over and drain. Pump the cartridge/damper a few times and it's empty. Do the same refilling, usually takes a minute or two. If I did this more often I could probably do a set of forks in a couple of hours. I will say it's a filthy job but with a clean workspace it's really not that hard with a little patience. Keep everything in line the way it came apart and replace in reverse.
All that said, I have no idea what the ESA adds to the procedure. Or how similar BMW forks are to Japanese. So, you should probably disregard this post as the inane ramblings of an old man.
I do not think that the post is "disregardable" in the least, especially seeing the topics of some of the other posts on motorcycle fora ... You are actually talking about working on the bike which, for me, is the best kind of post.
You have infinitely more experience than me when it comes to changing fork oil as I have never done this particular job. But from what I have read, there is a significant difference between electronically adjustable suspension and passive systems, with the former being not as straightforward. With your experience I think you'd have a great headstart on this operation.
To anyone who has done this or is planning to do it on the RS - Please consider documenting the operation in an article (with some pictures ..?) for the Forum / website. We all learn from each other, after all.
