Honda CRF450R vs. Husqvarna FC450 vs. Kawasaki KX450F vs. KTM 450 SX-F vs. Suzuki RM-Z450 vs. Yamaha YZ450F

The YZ450F may be the most brutal machine in the class when it comes to aggressive power delivery. The arm-stretching blue bike is fun to ride but can be little taxing on novices and even pros during a long moto.
