Engine
State-of-the-art 2-stroke technology in conjunction with a precise 6-speed transmission and a hydraulic clutch provide the basis for the superiority of the 85 SX in all junior race series.

Crankshaft
Thanks to the optimally dimensioned connecting rod, the crankshaft excels with minimum vibration and maximum durability.

Cylinders
The compact cylinder with 47 mm bore ensures that the 85 SX achieves peerless performance thanks to the ports dimensioned for optimum gas flow and the centrifugally-controlled exhaust valve. A reworked rear transfer port guarantees even better durability.

Cooling
Constant temperature control and hence consistently high performance are ensured by an intelligent cooling circuit with integrated crankcase cooling and two radiators.

Airbox
What’s good for the bigger KTM offroad bikes is good for the 85 SX: air filter replacement without tools in a matter of seconds.

Clutch
The 85 SX engine is equipped with a modern, hydraulic clutch actuation system from FORMULA, which guarantees smooth and very precise clutch control.

Chassis
The proven 43 mm upside-down fork with 270 mm of suspension travel and the PDS shock absorber ensure optimum traction and suspension comfort on the KTM 85 SX. Rebound and compression damping can be adapted individually to track and rider in no time at all.

Swingarm
As before, the newly developed swingarm is manufactured from lightweight aluminium in the form of a single casting. The very latest calculation methods have allowed weight to be reduced by 500 grams. Furthermore, newly designed chain links and brake-hose brackets, plus the proven chainguide from the full-size SX models have been employed.

Wheels and Brakes:
