How to Replace the Spark Plug on a Derbi Terra 125?

Model: Derbi Terra 125
Part: Spark plugs

Video tutorial

To replace the spark plug on a Derbi Terra 125, loosen the screws securing the side fairings of the bike, allowing them to be completely detached from their housing. After removing the panels, loosen the screws that secure the fuel tank, then remove the tank after disconnecting the hoses and connectors.

This will allow you to access the ignition coil underneath, reaching the spark plug located at the centre of the engine cylinder. Remove the old spark plug with a socket spanner, then insert the new replacement part and reassemble all previously removed components.
