Both bikes are capable of top finishes in the hands of a skilled rider. I'm not that skilled, so I'll take the KTM every time. It's easier to ride, is very forgiving (tolerating the sit-down-and-twist riding style), comes ready to ride, and has the magic button. The WR has serious horsepower and better high-speed suspension, but requires an aggressive style and MANY kicks to get it started when it stalls - and it likes to stall. And don't forget the aftermarket silencer and gas tank required to get the engine and ergos sorted out on the Yamaha. Most riders will do better with the KTM...
