How to change the engine oil of a KTM Duke 125?

To change the motor oil of the KTM Duke 125, make sure the motorcycle is positioned on a flat and stable surface, preferably using a central or side stand. Start the engine for a couple of minutes, so the oil warms up and becomes more fluid, making it easier to drain.

After turning off the engine, locate the drain plug located at the bottom of the engine. With a container under the engine, carefully unscrew the drain plug with a suitable wrench and let the used oil drain completely.

Once the oil has drained, make sure there are no more residues inside the engine, tilting the motorcycle slightly if necessary. After letting the oil drain, clean the drain plug and its gasket thoroughly, ensuring they are in good condition to prevent any leaks.

Carefully screw the plug back in place, without tightening it excessively. Now, locate the oil filler cap, usually located on the side of the engine.

Using a clean funnel, pour the correct amount of new oil, following the manufacturer's specifications. Once finished, replace the filler cap and start the engine for a few minutes to circulate the new oil.
