STEP INTO THE BIG LEAGUES

Developed on track and at an international level, the KTM 85 SX boasts significantly enhanced handling, improved power delivery, and notable enhancements in race pace over longer distances. All said - the KTM 85 SX is 100% READY TO RACE.

Powered On

The 2025 KTM 85 SX packs fresh firepower and gives an updated engine to starting gate. Weighing 120 grams less than the previous generation, the updated engine produces higher performance and optimised integration with the chassis updates. This means more punch in the low and mid-RPM range, more torque, and improved reliability.

Shifting Mechanism

Clicking into gear is made even smoother for 2025, with an update to the shift drum. Thanks to the new coating finish, shifting up and down the 'box is smoother, more reliable, and rock-solid even after many hours of use.

Frame

The 2025 KTM 85 SX boasts a completely new high-strength chromium molybdenum steel frame design, taken over the full-sized KTM SX range. Together with forged connecting parts, carefully calculated parameters of longitudinal flex and torsional rigidity, and incorporated sheet metal parts allow tailor-made stiffness. The new frame layout features a typical MX design without any cross tube behind the steering head. The rear shock mount is separated from the main upper frame tube like our full-size models, with frame protectors as standard.

Rigid Reinforcement Subframe

Now pay attention; this is a mouthful - 1-piece polyamide glass-fiber-reinforced aluminum. That's what the subframe is constructed from, for good reason. Not only does this reduce the weight of the whole construction, but it also features specifically engineered rigidity, delivering outstanding handling and rider feedback. It also makes for the perfect spot for integrated electronics, seat comfort, and hour meter mounting positions.
