The big changes to the 2017 KTM 450 SX-F are the 48mm WP AER fork that replaces 4CS design (that saves nearly three pounds), the top triple clamp is slightly more rigid to help the SX-F corner more precisely, the outer fork tube thickness decreased 1mm for increased flex in the fork, updated handlebar mounts that are slightly stiffer, aluminum head stays (instead of steel), a softer rear shock spring rate, and a multi switch handlebar mounted map and traction control switch. Yes, that’s right traction control! Check out Gary Sutherlin as he rides the new orange pumpkin around Pala Raceway in Southern California and hear what he thinks about the updated Austrian machine.
