I have a 2007 R1200GS but I am considering trading it for the new Tenere. Yes, it looks like I will get some cash for the trade which I think would be a fair amount, but I am interested in your opinions on the bikes themselves.

I don't have a car and live in Germany, so the bike is my only transportation mean. I have ridden K75RT, K1200GT, and the GS, all beemers. But these days, I like to ride more offroad and perhaps taking overland journeys. That is why I am starting to think about a smaller yet capable bike. Plus after my trip in Vietnam riding on a 125cc, I am more convinced that a smaller bike is better.

I like the GS and have ridden it for over a year or 15,000 km. I am thinking about the Tenere because:
1) I like to do more offroad
2) I like the design
3) I have more confidence in learning how to do some basic repairs myself
4) It feels smaller although it is not on paper, but I am 5'8" (172cm) tall so the GS just feels a tag bigger and heavier.

What I am not sure of about the Tenere is:
a) how is it handled on autobahn for a long stretch?
b) any maintenance issues on long distance travel?
c) it is only 20kg lighter than the GS but with only half the horsepower and torque as the GS
d) GS has this front shock in addition to the fork spring, which prevents from hard front-diving when hard braking, would driving a Tenere require significant changes in my driving style?

Honestly, my heart has already left the GS and gone to Tenere, so I'm looking for some harsh reasons why I shouldn't trade. Naturally, I am interested in any of your opinions and experiences.

Many thanks in advance.
