Vital MX: For 2017, KTM is once again releasing a Factory Edition 450 SX-F. Per the usual, the FE models are blinged out to replicate the factory team look. This includes the orange frame, team graphics, seat cover, DID wheels, Akrapovic slip-on exhaust system, and more. Beyond that, it has stiffer shock and fork settings from the 2017 production model, just to overall meet the comments of the media after riding the production 17 models. The bike also gains all the updates the 17 production bikes had over the 2016 Factory Edition models, such as updated AER 48 forks, new triple clamps, ECU updates, chassis updates, and more.

KTM Press Release:

The 450 SX-F FACTORY EDITION has led Ryan Dungey to a successful racing campaign for the last two seasons as he claimed back-to-back AMA Supercross Championships in 2015-’16 and the 2015 AMA Pro Motocross Championship. Additionally, as the lightest and best performing bike in its class, there’s no question why the 250 SX-F FACTORY EDITION is the bike of choice for the Troy Lee Designs/Red Bull/KTM team. The 2017 FACTORY EDITION models have been proven to be the most READY TO RACE machines in their class.


A compact SOHC engine effectively delivers explosive power to the ground, thanks to traction control, launch control and a two-position map switch. Updated WP AER 48 forks and rear shock elevate the 450 SX-F’s already-stellar handling, while a titanium Akrapovic muffler sheds weight. Top it all off with CNC-machined orange anodized triple clamps, D.I.D. DirtStar rims and Red Bull KTM Factory Racing replica graphics and you have a recipe for success at any level of racing

2017 Updates:

  • UPDATED WP AER 48 front fork with a new air seal, air piston and rebound spring on the air leg, along with a new piston on the damping side for improved performance.  
  • UPDATED settings for both the WP AER 48 front fork and rear shock.
  • Handlebar map switch that also activates traction control and launch control for enhanced traction for the start, middle and end of the race.
  • Orange anodized CNC-machined triple clamps for optimized clamping force that is tuned to the WP AER 48 front fork for exceptional handling.
  • A lightweight chromoly steel frame provides high torsional rigidity with tuned longitudinal stiffness resulting in excellent handling and energy absorption.
  • KTM’s “No Dirt” footpeg design keeps the peg’s pivot from becoming clogged, ensuring the footpeg is always in the correct position.
  • Super lightweight Galfer Wave rotors, CNC-machined hubs, high-end D.I.D. DirtStar rims and Dunlop GEOMAX MX3S tires.
  • Akrapovic titanium slip-on muffler is lighter than the standard 450 SX-F muffler.
  • Airbox and filter design provides maximum performance with fast “no tools” air filter changes.
  • “No Dirt” shift lever prevents dirt from fouling the lever joint to ensure proper shifting in any condition.
  • Factory replica graphics, orange powdercoated frame, orange anodized sprocket and front disk guard complete the READY TO RACE 2017 450 SX-F FACTORY EDITION.
