Why is this such a freaking hard concept to understand? Many would like all of the virtues of a sport combined with only 4x4. It has nothing to do with utility! F' utility(for me anyway). I want a "light" 4x4 Sport. If it takes 25-50lbs added to a regular sport, so be it. You might as well make it big bore while you are at it. This would help with the "low end" that some have complained about, though I know the YZF motor could be tuned for more bottom end and would be sufficient.

And as far as if it would handle "track" conditions, come on fellas, they have them that run on pavement already. They just need to transfer the technology. They even have setups where you can choose your ratio; 50/50, 40 to the rear and 60 to the front, 20/80, whatever. This, I believe would be the most desireable and benificial. It would provide just a little bite for the track or none at all and full on 4x4 for the mud. Have it change on the fly.
