THE NEXT STEP TO GREATNESS
The 2022 KTM 85 SX offers a real taste of the big leagues by giving young racers a real-world big bike experience with an impressive list of componentry and blistering performance. This is also thanks to its lightweight, high-quality frame which houses a compact rocket ship of an engine, delivering unrivaled rideability, providing the ultimate platform for aspiring racers.
It took extreme levels of ingenuity to fit the race-winning formula of KTM's bigger 2-strokes into a compact 85 cc engine. The super-compact powerplant is fitted with a 6-speed gearbox and delivers class-leading power and rideability throughout the entire rev range. The powervalve plays a key role in tailoring power delivery to suit track conditions and rider ability, ensuring that the only rider surprised by the incredible performance is the competition.
The cylinder on the KTM 85 SX has a bore and stroke of 47mm and 48.95 mm respectively. It features a sophisticated power valve system, which controls both the exhaust valve and the sub exhaust ports, giving the bike excellent torque and power delivery. This translates into significant midrange performance, reducing the need to overwork the clutch in loamy or sandy conditions. An adjuster screw allows the opening time of the power valve to be adjusted to suit rider preference and track conditions.
The KTM 85 SX features a lightweight 6-speed gearbox, engineered to take a beating. The gear ratios have been developed to perfectly match the characteristics of the engine, with easy and precise shifting allowing the rider to slot in the next gear quickly and confidently. The gearbox also features a driveshaft that uses a screw to secure the front sprocket, and a diaphragm spring instead of a circlip, to ensure the front sprocket remains firmly in place. As with all KTM SX models, the KTM 85 SX transmission has a "no-dirt" gear shifter which, like the footpeg design, prevents dirt build-up.
Boasting a strong and reliable clutch with an extremely compact design, the KTM 85 SX allows riders to actuate the clutch level with ease, thanks to the FORMULA hydraulic system, which conveniently ensures that play is always compensated for. This means the clutch "bite" point remains consistent throughout the ride and under all conditions.
Maintaining the optimal engine temperature is crucial to ensuring consistent horsepower throughout the ride. The KTM 85 SX features radiators which are positioned for a lower center of gravity. Their design matches the shrouds perfectly and offers a great slim feel to the ergonomics. By using CFD technology (computational fluid dynamics) together with a clever coolant circuit routing, the innovative system ensures the optimum engine temperature for the highest performance, no matter what the conditions. The radiators also feature special protectors that serve not only as protection from flying rocks and debris but also as a brace that disperses energy around the radiators in the event of an impact.
The exhaust system has been designed to perfectly match the engine's power characteristics and contributes to the outstanding all-round performance and rideability. The header pipe is produced using a 3-dimensional stamping process. Once the components have been shaped, they are robot welded to ensure the highest level of quality, consistency and durability. The lightweight and compact silencer has been reworked with improved packing wool (40 g lighter), guaranteeing that sweet 2-stroke sound and falling safely within the noise limits for racing.
The frame on the KTM 85 SX is a scaled-down version of the multi-championship-winning full-size frames. Made from hydroformed chromium-molybdenum steel tubes that are robot welded, the frame is pin-point accurate, ensuring the highest levels of consistent quality and flex characteristics.
The KTM 85 SX features a black powercoated Excel rim combo, with a 17-inch front wheel and a 14-inch rear, for slighty shorter riders. These are mounted on CNC-machined hubs and wrapped in MAXXIS tires which deliver exceptional straight-line stability and excellent traction on a wide variety of terrain.
Bringing this little screamer to a stop is down to the Formula brake system with radial calipers - four pistons in front, two in the rear - with lightweight Wave brake discs. The system is the benchmark in terms of controlled action and braking performance, ensuring powerful and confident braking.
The KTM 85 SX airbox is a masterclass in design, optimizing the tiny space available to deliver the best possible performance, while still maintaining the highest level of filter protection. The air filter is easily accessed, without tools, by removing the left side panel. The Twin Air filter and filter cage design feature a simple, secure mounting system, making filter maintenance quick and easy, which means less time in the pits, and more time winning races.
