To replace the spark plug of the Aprilia RX 125, you need to completely remove the seat of the motorcycle to access the components underneath: below it, you will find the battery and the fuel tank. Both of these components must be removed from their housing by unscrewing the fixing screws and disconnecting the connectors: this will give you access to the top of the cylinder, where you can disconnect the coil and pull out the spark plug below using a suitable socket wrench. After removal, you can insert the new spark plug, reassembling all previously removed components.
