FEATURES
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.
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.
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.
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.
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
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.
WHEELS AND TYRES
Keeping the 2025 KTM 85 SX tracking is a set of Black Excel-branded rims and CNC machined hubs fitted with MAXXIS MAXXCROSS MX-ST tires. Not only does this combination deliver outstanding performance on a variety of terrain, but the pattern design and rubber compound deliver exceptional straight-line stability and excellent traction. As always, the KTM 85 SX is available for order with two rims sizes -19/16 and 17/14.
WP XACT FORK
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.
WP XACT SHOCK
Mirroring the latest technology found in the full-size motocross range, the 2025 KTM 85 SX features an all-new fully adjustable WP XACT monoshock. This is perfectly matched to the front forks, bringing ideal balance and damping characteristics, along with improved traction, a more planted feel, and control at speed.
