Right out-of-the-box, the WRR is faster and has a little more available power due mainly to the FI. The carb on the KLX requires it to be super lean, and Kawasaki equipped it with a really choked down muffler. The price difference between the 2 bikes, however, makes it very easy and logical to mod the exhaust and install a Dynojet kit. This changes the KLX dramatically. Otherwise the 2 bikes are very similar in weight and suspension performance. I wouldn't mind having either bike, but I was able to find a used '06 model KLX for a decent price so it was a moot point.
