Model: Ktm Duke 390
Part: Engine oil

Replacing the motor oil in the KTM Duke 390, as we can see in this tutorial, is an extremely simple and quick operation. First of all, we wait for the engine to cool down enough, then we remove the lower protective cover, locate the front drainage hole bolt and unscrew it using a 14mm socket wrench. We then unscrew the secondary filter bolt with a 19mm wrench, clean it from any dirt residue and proceed to replace the main filter. At this point, all that's left is to reassemble everything and pour the new oil through the appropriate hole.
