2018 450 MX BIKES ON THE DYNO

 How much power do the 2018 450s really make? We tested all six on the FMF Dynojet dyno in preparation for our 450MX shootout, which will appear in the December issue. In case you missed it, you can watch the Dirt Bike 2018 450 MX shootout video by clicking here. In the print edition, we don’t have room to show the actual numbers or the torque curves, so for you number-crunchers, here’s the raw data. On the chart above, the bikes are coded by the following colors:

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