To change the oil on a KTM Duke 125, you can follow these general steps:
Gather the necessary tools and materials: You will need a socket wrench or a suitable tool to remove the drain plug, a new oil filter, a container to catch the old oil, a funnel, and the appropriate type and amount of new oil (refer to the owner's manual for specifications).
Warm up the engine: Start the motorcycle and let it run for a few minutes to warm up the engine. Warm oil flows more easily and helps to remove contaminants.
Locate the drain plug: The drain plug is usually located on the bottom of the engine. Refer to the owner's manual or consult a service manual to identify the exact location.
Position the catch container: Place the container beneath the drain plug to catch the old oil.
Remove the drain plug: Use the appropriate tool to loosen and remove the drain plug. Allow the oil to drain completely into the container. Make sure to handle the drain plug carefully as it may be hot.
Remove the oil filter: Locate the oil filter, which is typically located near the drain plug. Use an oil filter wrench or a suitable tool to loosen and remove the filter. Allow any remaining oil to drain into the catch container.
Install the new oil filter: Apply a thin film of oil to the rubber gasket on the new oil filter. Hand-tighten the new filter onto the filter housing. Ensure it is securely fitted but do not overtighten.
Replace the drain plug: Once the old oil has finished draining, clean the drain plug and reinstall it. Tighten it securely, but again, be cautious not to overtighten.
Add new oil: Locate the oil fill cap or dipstick, usually on the side or top of the engine. Remove it and insert a funnel. Slowly pour the recommended amount of new oil into the engine. Check the oil level using the dipstick or sight glass to ensure it is at the proper level.
Clean up: Wipe off any spilled oil and ensure that the drain plug and oil filter are clean and free of leaks.
It's important to consult the owner's manual specific to your KTM Duke 125 for detailed instructions and to ensure you use the correct type and amount of oil. If you're unsure about performing the oil change yourself, it's recommended to have it done by a qualified technician.
