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

The Kawasaki barks cleanly out of corners, but our test crew was expecting more of a hit and a stronger pull at higher rpm. Throttle response is best when Kawasaki’s “lean” DFI power coupler is plugged into the KX’s ECU.
