you can go much faster in the woods with the KTM than the WR/YZF hands down and less maintenence and lighter weight... 2007 KTM 300XC = 226 lbs 2007 YZ450F = 220 lbs I have not personally ridden a KTM 300XC but I have heard good things (great powerband for offroad) and bad things (suspension is hard to get set right, if ever, vibrates). I do however own an '03 RM250 that is set up very nicely for the woods and it eats KTM's for lunch in the woods. I also have an old YZ426 that is set up for the woods and it rips too. Now I am working on my new '06 YZ450 and it's going to be awesome. I guess what I am trying to say is that it is all about proper set up and it boils down to if you want a thumper or a pinger. I guess if you wanted the best bike for the woods right off the showroom floor then the KTM 300 would get my nod. By the way...I still do not understand the argument that 2T's require less maintenance. Unless you are really easy on a 2T they need to be opened up for rings and pistons far more often than a YZF needs for valve adjustments, rings, etc.
