The numbers
Where the price sits
2 listings match this machine, and the rule wants 3 before it will call anything a market — a median off fewer is their average. The ask is shown on its own instead.
A comparable is the same make, model, year and trim, within 3,999 miles of this odometer and 500 miles of this dealer. Unpriced listings are ignored, this one is excluded, and a dealer posting the same machine twice counts once.

The KTM 450 SX-F boasts one of the strongest and most versatile 4-stroke powerplants in the paddock, with its SOHC engine proving to be the perfect example of advanced engineering. With a peak power output, and an overall engine weight of only 59 lb (26.8 kg), you'll leave the competition with more than a little mud on the face.Calm Under FireAbsolute ControlGet ready for a full-on berm assault. The KTM SX and SX-F machines received major frame updates directly from KTM Factory Racing efforts. For starters, the area around the rear shock mount is streamlined, with engine mounts and cut-outs for improved chassis flex. The front area of the frame has an optimum wall thickness with renewed engine mounts.Hit The Big StuffWP XACT Fork Let's get the technical parts out of the way first; the 48 mm WP XACT AER forks fitted to the KTM SX and SX-F line-up features a capsulated air spring and pressurized oil chamber for progressive and consistent damping, while oil and air bypasses reduce pressure peaks. In combination with the mid-valve damping system, all this provides exceptional feedback and rider comfort. The fork also has settings which not only compliment the frame and rear linkage, but ensures stellar performance at all levels. Speaking of settings, these are easily adjusted via a single air pressure pre-load valve, as well as easy-access click adjusters for compression and rebound. Additionally, the WP air pump needed to adjust the fork's air pressure is provided as standard in the buy-pack.
