I have both a WR250r and a 1200GS. I'm currently in S. Korea, a common jumping-off-point for RTW trips heading West. I have the GS here... The thought crosses my mind a lot...
It's nearly 50/50 I think. The GS would kick my ass at times, in bad conditions. At the same time, the WR would do the same when I had a decent piece of tarmac ahead of me.
I think the WR is a better machine for the job, when you get all the way down to brass tacks.
I may be totally wrong on this, but I think one thing (seeing your bikes together) your KTM has going for it is it's ALL black. The WR by contrast stands out like a sore thumb. I wonder if this "camouflage" might be valuable on the WR in other countries. In other words, perhaps you need to make it look a little shitty?
