How to replace the spark plug of the KTM Duke 125.

Model: Ktm Duke 125
Part: Spark plugs

Video tutorial

In this video, we see how to replace the spark plug on the KTM Duke 125: you need a 13 mm magnetic socket wrench to remove it without worrying about it falling inside, as that would really be a problem. Additionally, the space to work in is quite limited, making the operation really challenging.

Once we have removed the used spark plug, we place the new one in using the same system with the magnetic socket wrench. Once positioned, we screw it in by hand first, and then tighten it with the wrench until it is secure (without over-tightening it). We then put the rubber cap back on, and the operation is complete.
