Back from hybernation... 7 months later... and here I am. How is the shifting now? How many miles do you have now?
I've noticed (also with my past K1200R ownership) that BMW bikes tend to be engineered in a tighter tolerance than their Japanese counterparts. The shifting is extremely tight and precise. Both my K1200R and S1000RR kept getting better with miles and seemed to finish breaking in passing 6K miles. Although, they kept getting better until passing 12K miles.
Here's something that I've learnt way back... similar to Bernardo's way to preload the shifter and let it slide in with the clutch engagement, I don't pull the clutch all the way, just enough to let the gear click in. You can change gear even smoother this way and still pretty quick compared to using the quick shift. It's not really about using 1, 2, or 4 fingers... it's about how much.
