Why the 85 SX 17/14

9 highlights
01 KTM 85 SX 17/14 — ADJUSTABLE SUSPENSION

ADJUSTABLE SUSPENSION

Either end of the 2025 KTM 85 SX's WP XACT suspension is adjustable. Upfront, the WP XACT AER fork can be easily adjusted with the use of an air pump. This allows riders to tailor the KTM 85 SX to their specifications, weight, or track conditions. At the rear, the new WP XACT monoshock is fully adjustable for preload, compression, and rebound.

02 KTM 85 SX 17/14 — ENGINE

ENGINE

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.

03 KTM 85 SX 17/14 — EXHAUST

EXHAUST

Giving this junior rocket its signature 'Braaap!" is an all-new exhaust system, featuring a new manufacturing process - just like on the full-size 2-stroke KTM SX range. Thanks to the removal of seams between individual sheets, the exhaust flow is optimized, resulting in substantial improvements when it comes to thermodynamics. Simply put - this pipe performs.

04 KTM 85 SX 17/14 — ERGONOMICS

ERGONOMICS

Meet the 2025 KTM 85 SX in a dark alley, and you'd be forgiven for thinking it was one of its bigger brothers. With a carefully scaled-down design that mimics that of the full-sized KTM SX range, this little weapon has unparalleled aesthetic appeal. What's more, it also provides young riders with an exceptional riding experience and sensation, getting them ready to step up to the big leagues.

05 KTM 85 SX 17/14 — FRAME

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

06 KTM 85 SX 17/14 — RADIATORS

RADIATORS

The 2025 KTM 85 SX features new state-of-the-art radiators produced by Pankl, inspired by the full-size SX concept. These feature the same design, albeit shortened to fit the 85cc needs and size, and work to ensure the engine is running at optimal temperatures when being ripped around the track, lap after lap.
