Thanks to its compact engine delivering explosive but controllable power, it’s the weapon of choice for the Red Bull KTM Factory Team and their champ, Ryan Dungey. Ridden at its hardest, this bike is quick enough to rule the AMA Supercross Championship. Its secret? Sweet handling and gut-wrenching grunt. Winners, line up here.
