2026 KTM SX 85 17/14

STEP INTO THE BIG LEAGUES

The last step awaits. The KTM 85 SX 17/14 is ready to raise the speed for you. Developed on track and at an international level, the KTM 85 SX 17/14 boasts significantly enhanced handling, searing power delivery and proven READY TO RACE DNA through its components and pedigree. You spoke, we listened. We developed. Now continue the journey. Fast.

01. Before The Gate

LIGHT IT UP!
COMBUSTION CHAMBER
The combustion chamber was recently redesigned with a smaller spark plug. This makes for more effective and efficient combustion, reducing the compression ratio generating more power and torque.

PUMPED UP!
ADJUSTABLE SUSPENSION
Don't worry about change. The KTM 85 SX's WP XACT suspension is adjustable upfront and at the rear. The WP XACT AER fork can be easily modified with the use of an air pump. This allows riders to tailor the KTM 85 SX to their specifications, weight, or track conditions. The WP XACT monoshock is fully changeable for preload, compression, and rebound.

RACER, START YOUR ENGINE!
IGNITION
The KTM 85 SX has a CDI box from Hidria bringing lots of processing power and a fiery ignition curve. The benefits? A faster ignition process, smoother engine operation, and shorter heating time in colder temperatures.

02. Start Strong

POWERED ON
ENGINE
The KTM 85 SX holds the kind of firepower that makes it the reference in the start gate. Weighing 120 g less than the previous generation, the engine produces high performance and optimized integration with the chassis. This means punch in the low and mid-RPM range, torque, and reliability.

MORE POWER
FACTORY PERFORMANCE KIT
Boost the performance of your KTM 85 SX by installing the 105 Factory Kit, ideal for tackling larger track layouts. This kit includes enhanced engine components, a cylinder head, a combustion chamber insert, a CDI control unit, and a spark plug.

03. Calm Under Fire

FLUID RIDER MOTION
ERGONOMICS
Meet the 2025 KTM 85 SX in a dark alley, and you'd be forgiven for thinking it was one of its bigger siblings. 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.

STEADIER ON THE GAS
THROTTLE CABLE
Goodbye to kinks, hello to increased durability. We've applied an additional stabilizer cap to the throttle assembly to hike the quality.
Now, just hold it open wider and for longer.

04. Hit The Big Stuff

BRINGING THE BACKBONE
FRAME
Premium handling and feel comes through a high-strength chromium molybdenum steel frame design, taken from 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 for tailor-made stiffness. The frame layout features a typical MX design without any cross tube behind the steering head. The rear shock mount is separate from the main upper frame tube like our full-size models, with frame protectors as standard.

RIGID REINFORCEMENT SUBFRAME
We still bank on our 1-piece polyamide glass-fiber-reinforced aluminum subframe. Not only does the material reduce the weight of the whole construction, but it also features specifically engineered rigidity, delivering outstanding handling and rider feedback. It's also the perfect spot for integrated electronics, seat support, and hour meter mounting position.

05. Maintaining Momentum

PRECISE, LAP AFTER LAP
RADIATORS
The KTM 85 SX features state-of-the-art radiators produced by Pankl, inspired by the full-size SX range. These feature the same design albeit shortened to fit the 85cc needs, size and works to ensure the engine is running at optimal temperatures when being ripped around the track, lap after lap. For 2026, a new threaded radiator cap allows easier and faster opening with reduced force.

BREATH IN DEEP
AIRBOX AND FILTER
The airbox concept has been designed with precisely positioned inlet ducts to prevent air deformation, ensuring maximum airflow and filter protection. The Twin Air filter can be easily accessed without tools by removing the left side panel.
