2018 450 MX BIKES ON THE DYNO

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:
