The R1100GS I bought in 1995. What a great bike; it’s done tons of highway and some off-road miles, and never let me down.
In with the new; an R1200RT:
I’m still getting used to it, and I’m deliberately not using all the fancy, distracting buttons and switches until I’m totally comfortable with it. For example: BMW got rid of their old turn signal switches (a directional button for each thumb) and now uses a traditional rocker switch on the left thumb now; it’s harder to signal, and I have to practice.
On this morning’s commute, compared to the GS I felt like I was in a bubble of air; the amount of wind and noise was dramatically reduced. I guess that’s the whole point of a touring faring.
