2027 KTM 450 SX-F

2027 KTM 450 SX-F

The benchmark, still. Victories and championships in AMA Supercross. Victories, championships and history in MXGP. What comes next in the story? You write it. Take down the best and reign over the rest with the one and only standard.

Features may include:

• SIMPLE SUSPENSION TUNING

Just like always, both ends of the suspension offer a simple setup with no tools needed, so you can hunt down the podium in complete control. At the back, a dual compression adjuster that works by hand lets riders change high- and low-speed settings within seconds. Up front, the forks can also be tweaked with ease, thanks to hand-adjustable clickers located at the top cap and at the bottom of the fork shoe.

• AIR FILTER BOX

Built with maximum airflow as the goal, the air filter box uses inlet ducts placed with precision to prevent air deformation and keep the filter protected. The Twin Air filter and its support design use a straightforward, fail-proof mounting system so the filter goes in safely and accurately, and taking off the left side panel gives tool-free access to the filter for easy maintenance at the track. Every SX and SX-F model also comes with a vented air filter box cover in the by-pack.

• EASE OF SERVICE

Across the KTM SX and SX-F lineup, engineering and design give riders service parts that are easy to reach, plus suspension adjustability. That allows quicker maintenance at the track and in the off-season, and it makes motocross simpler for novice riders who don't have pit crews. For 2026, the new threaded radiator cap opens more easily and quickly and takes less force.

• PERFORMANCE

Tilting the KTM SX-F engine back by 2° results in much better mass centralization and less overall weight, which benefits handling and anti-squat behavior. Working together with the mapping switch, a silencer gives improved response, along with an exhaust note that's slightly quieter.

• TOTAL CONTROL

Prepare to attack the berms all-out. Revised frame updates on the KTM SX and SX-F machines were developed with KTM Factory Racing's input. To begin with, the section surrounding the rear shock mount has been streamlined, with engine mounts and cut-outs optimized for better chassis flex. At the front, the frame has optimized wall thickness along with updated engine mounts.
