AIRBOX

The robust one-piece design airbox on the KTM XC range features an air inlet sleeve and snorkel, which prevents deformation and improves airflow. But don't fret, toolless filter access is retained, with an intuitive filter mounting system and protection against dirt intrusion.

Easy Suspension Adjustment

As always, the suspension boasts an easy tool-free setup at both ends, ensuring you chase down the podium in total control. On the rear, a hand-adjustable dual compression option allows riders to adjust high- and low-speed settings in a matter of seconds. The forks on the front end are also easily modified thanks to hand-adjustable clickers on the bottom of the fork shoe and top cap.

More Usable Power

The KTM 125 XC has always represented the very best of unmatched power and lightweight construction. The simplicity and low maintenance cost of the 2-stroke engine have made it a favorite among hardcore cross-country racers for generations. The KTM 250 XC rolls into the pits with the same legendary performance and a low engine weight of just 23.9 kg (52.6 lb) – with a mission to maintain its status as the benchmark to beat.

Fuel Injection

With Electronic Fuel Injection setting the standard, there's no more jetting setup pre-race, and thanks to the Keihin EFI, the ECU coming from Vitesco and reed valve case design, you can be guaranteed of laying down optimal power at any altitude, all of the time.

Selectable Maps

Once again slicing into the 125 cc class with the leading edge of technology, the 2025 KTM 125 XC features a map select switch as standard, allowing the racer to switch between 2 perceptible engine maps. Map 1 provides the ultimate power delivery to dominate hard-pack surfaces, while Map 2 gives you the edge in soft, sandy conditions
