The 2025 KTM 85 SX packs fresh firepower and gives an updated engine to the starting gate. Weighing 120 g less than the previous generation, the updated engine produces higher performance and optimized integration with the chassis updates. This means more punch in the low and mid-RPM range, more torque, and improved reliability.
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.
Featuring the latest in suspension technology, the 2025 KTM 85 SX is fitted with a state-of-the-art WP XACT AER fork. These ultra-lightweight, 43 mm USD forks feature exceptional damping and comfort, allowing the rider to push the limit confidently.
Stopping power comes from the Formula brake system with radial calipers (four pistons in front, two in the rear) and lightweight Wave brake discs. It offers controlled action and powerful braking.
all-new, “no-dirt” designed footrests offer a bigger surface area to step on while being less susceptible to hooking on deep ruts, and take-offs when scrubbing. The result? Better control and more leverage
The 2024 KTM 85 SX features a white and orange plastics combination, orange seat cover, and eye-catching graphics, showcasing its race-winning intent.
