Performance and rideability are enhanced with a custom exhaust system that exactly matches the engine’s power characteristics. A three-dimensional stamping procedure is used to create the header pipe. Finally, the components are robot-welded to assure the best possible quality, uniformity, and longevity. To keep the lovely 2-stroke sound and stay under the race noise regulations, we rebuilt the lightweight and compact silencer with superior packing wool (40 g lighter).


KTM’s superior 2-strokes had a formula that could only be put into a tiny 85cc engine with tremendous inventiveness. Significant weight reductions are achieved without losing strength or durability thanks to an innovative production method. There’s little doubt that this bike’s 6-speed gearbox produces class-leading power and rideability across the rpm range. To ensure that the only rider shocked by the extraordinary performance is the competition, the power valve plays a vital role in customizing power delivery to fit track circumstances and rider skill.

The KTM 85 SX airbox is designed to make the most of the tiny space available while yet providing the most significant possible degree of filter protection in the process. By eliminating the left side panel, the air filter may be extended without the need for tools. KTM has made the procedure of installing a new, clean air filter as simple as possible since they know that air is the source of the motor’s power. Filter maintenance is made simple and precise thanks to the Twin Air filter and filter cage design, including a simple, secure mounting method.


A scaled-down version of the standard KTM frame is used in the KTM 85 SX. Hydroformed chromium-molybdenum steel tubes are welded by robots, guaranteeing the highest quality standards. To provide outstanding agility and high-speed stability, the suspension and flex characteristics have been designed to operate together seamlessly. Orange powder coating and standard frame protectors are included on the 2020 model year frames.

With “no-dirt” footpegs, the KTM 85 SX provides total control in all situations thanks to a simple but efficient self-cleaning mechanism.


The KTM 85 SX has a tapered aluminum handlebar that is robust, lightweight, and contoured to fit the bike’s ergonomics well. ODI lock-on grips are standard on the bike, and they have vulcanized clasps on the right and lock-on grips on the left, both of which may be mounted without adhesive or wire.
