Nice write-up. Thanks for posting it here!
I've considered buying an older RT or K bike for touring use, but definitely not a 1600. I only ride alone, and the extra power (and size, weight, and expense) of the 1600 would just be wasted on me. Not to say it would be a bad choice; it's just overkill for my needs.
FWIW, I'm on my first BMW - an R nineT Pure - after long-term ownership of a 6th gen. VFR. It's different. It's been mostly great. Being a naked boxer twin, some of the maintenance is easier. But some is harder, too. Replacing the battery, for example, which I'll be doing soon is a pain. Also, any BMW dealer service is very expensive. Still, I don't miss pulling the left fairing off my VFR for a simple oil and filter change.
