I bought a used WRr this March for a great price. It is hands down the best MC I've ever owned. I can only have one bike due to space and finances. So I need a bike that can commute, and do the trails (5000 miles on the street 750 in the dirt). My commute is 80 miles round trip, so maintenance intervals are important as well. I don't get as much trail time as I would like, but I do get out on them whenever I can, and on longer planned off-road trips I spoon on the Trackmasters. That is my reality, and why it makes a bike like the WRr or CRF250l the best options for me.
If I were buying new, it would have been the CRF as it would suit my needs as a bike and the price is significantly lower. KTM may make excellent bikes, but they are not in the same category as these bikes. Certainly they are superior off road, and in overall power, but that was not what I was looking for. I got what I was looking for, fuel injection, very low maintenance on a versatile dual sport machine.
