It features the new power valve, which is optimized for the best and efficient power delivery. This engine provides more aggressive ride than 2018 KTM 65 SX and 2018 KTM 50 SX. The new cylinder features the new ports to improve the performance and best response. This system monitors the exhaust valve and the sub-exhaust port for significantly improved torque, power, and controllability. This dirt bike receives the significant increase in the mid-range performance reducing the use of the clutch. There is an adjuster screw as well, which allows the opening time of the power valve to be adjusted to suit the performance of rider and track conditions. The crankshaft is now lighter with an optimized balancing to reduce the vibration and oscillating mass. The rotational inertia of the crankshaft has increased by 0.5kg improving the torque and ride-ability. The new hydraulic clutch mechanism guarantees an easy clutch action with the well-defined modulation. It features the new diaphragm spring clutch, which is about 0.4kg lighter and compact with the added durability. Its new exhaust system is perfectly suited to the engine’s power characteristics plus it contributes to the outstanding performance and ride-ability. The header is made with the 3-dimentional stamping process by WP Performance Systems. Once the components are shaped, they are robot welded to guarantee the best quality and durability. It features the silencer of 50 mm shorter with improving mass centralization. The crankcase is being manufactured using the high-pressure die-cast production process with the wall thickness to the minimum while retaining strength and durability. The design of cases is more compact and it aims at positioning the shaft arrangements to the center of gravity for improved handling. Its crankshaft is much lighter with an optimized balancing to reduce vibration and oscillating mass. With this removing of weight, the rotational inertia of the crankshaft has increased by 0.5kg improving torque and ride-ability. It is possible due to a sized lightweight connecting rod, the crankshaft is distinguished by the minimum vibration and maximum durability.

It has the new throttle assembly, which allows an easy free play adjustment. The ODI lock-on grips on its left side provide easy grip changes plus it does not require any wire or glue to be attached and secured. The Formula braking system with the radial calipers provides the best braking experience. It has four pistons in the front while two in the rear. It comes with the lightweight wave brake discs featuring the front diameter of 240mm and rear diameter of 210mm. The size of a piston on the rear caliper is being reduced by 2mm to 22mm. It comes in combination with the new rear brake lever to provide an improved modulation and feeling. The constant temperature balance for consistently high performance is ensured by the use of an intelligent cooling circuit with an integrated crankcase cooling and two radiators. Like the older model i.e. 2017 KTM 85 SX 17-14, this new dirt bike routes the coolant from the head of a cylinder through the frame triangle directly to aluminum radiators made by WP. This system is very efficient due to the flow optimized internal circulation and CFD-calculated ventilation. In addition, the new radiator protections improved the head dissipation. It is integrated into the front part of a shroud to protect the radiators from mud. The new air filter used in it can easily be changed within seconds without any use of a tool.

The new WP performance system uses the chromium molybdenum steel frame is constructed using the hydro formed tubes. These tubes are joined by the precision robot welding to attain high level of consistent quality. Its frame is about 0.7kg less in weight as compared to previous version. The overall geometry is carefully designed to improve handling and comfort. The new laterally mounted cylinder head mountings, the torsional rigidity in increased by 7% while the longitudinal stiffness is reduced by 25%. This modification allows the frame to move in harmony with the new suspension for maximum comfort, improved agility and best stability. This frame comes with the new ‘No Dirt’ footpegs, which prevent the build-up of dirt collected through rough surfaces.
