The 2020 KTM 450SX-F is here and we have enough time on it to present the latest episode of The ’20s Video Series, direct from Fox Raceway. The bike is a production version of the Factory Edition that arrived last winter. It has the same suspension set up and overall layout. The biggest difference is the mapping. KTM now has a much more effective “aggressive” map loaded into the EFI system, and it’s available on the fly through the handlebar-mounted map switch. The bike also has a vented airbox cover that comes in the parts kit. Riders will no longer have to butcher their one and only cover to get a little more snap out of the motor. The full test of the 2020 KTM 450SX-F will appear in the print edition of Dirt Bike soon.
