I really like the Dakar/Sertao setup. Ive been looking for a used Dakar, but get a kick of owners wanting a huge premium thinking the bikes are *that* special. Thanks, but I'll spend a few grand extra and get a new Sertao, or for the same price get a lightly used F800GS - twice the power for 10 lbs more weight.
Rumors are that BMW is going to push the Sertao as the most common single (as opposed to the standard G650GS), if thats the case there should be a lot of good used ones on the market soon (next few years).
My hunt continues.....
