2027 KTM 85 SX 19/16 STEP INTO THE BIG LEAGUES The last step awaits. The KTM 85 SX 19/16 is ready to raise the speed for you. Developed on track and at an international level, the KTM 85 SX 19/16 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. 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. Start Strong SHIFTIN' GEARS Shifting Mechanism Clicking into gear is even smoother with a recently updated shift drum. Thanks to the coating finish, shifting up and down the 'box is smoother, more reliable, and rock-solid even after many hours of use. 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. MORE BRAAAAP! 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. Calm Under Fire IN TOUCH WITH THE RIDER Triple clamps, Bars & Pegs The triple clamps feature an improved upper clamping mechanism that is more resistant to dirt and water, extending the lifespan of the steering head bearings. The required wrench size has been reduced to a convenient 17 mm. The tapered black Neken-branded handlebars are made from high-quality aluminum alloy, ensuring top stability, vibration damping, and safety. The no-dirt footpegs provide a larger standing surface while being less prone to catching in deep ruts or during scrubs. The result: better control, more leverage, and more hold when charging the holeshot. For smaller riders moving up from the KTM 65 SX, two rear brake lever length adjustment options are provided. 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. FULLY FUELED Tank The tank design fits the frame concept and bodywork, providing the ideal support for young knees to grip, and 1.42 gallons (5.4 liters) of screaming fury to rip. Hit The Big Stuff RACING ON RAILS Wheels and Tires Keeping the show on the dirt are 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 compounds deliver exceptional straight-line stability and excellent traction. As always, the KTM 85 SX is available in two rims sizes -19/16 and 17/14. 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 st
