Heard somebody saying that s10 is better off road bike. Kidding right!?
If by off road they ment those dirt highways, then the R1 is just as good as s10.
The thing is, i don't see it as a second bike. I own xtr660, and that one makes much more sense with almost half the weight of S10. Few mods and it turns out to be a cheap, reliable and capable off road machine, while being comfy for whatever else. Than again, WR is the way to go if you plan to attack the mountain, woods,(skills needed) and putting commuting aside.
