Before You Start: Model–Specific Call–Outs
- Oil Capacity: 500ml (milliliters) of oil is required for the 2008 KTM 65XC.
- Recommended Oil: Motorex is advised by KTM for best longevity and performance.
- Drain Plug Torque: Always torque the drain plug to 50 Nm (Newton meters).
- Drain Plug Location: Left side behind the shifter (use 13mm socket/wrench).
- Oil Level Checks: Always check oil level with engine at operating temperature to avoid false reading.
- Crush/Copper Washer: Replace if worn to prevent leaks.
- Hot Oil: If the engine was just running, oil can be extremely hot – take precautions to avoid burns.
Step–by–Step Instructions
-
Warm up your engine.
Start and run your KTM 65XC for a few minutes. This heats and thins the oil, ensuring faster, more complete drainage. Turn off the bike and let it rest securely on a stand.
-
Remove the oil fill cap.
Remove the oil filler cap on the clutch cover to allow air in and help the oil drain faster. Clean around the cap and filler hole to prevent dirt from entering the engine.
-
Position your oil catch pan.
Slide the pan under the left side of the engine, directly below the drain plug located behind the shifter.
-
Remove the drain plug.
Use your 13mm wrench or socket to carefully loosen and remove the drain plug. Allow the old oil to drain completely. Watch for hot oil. Cleaning the magnet on the plug is recommended.
-
Flush the engine case (optional, but recommended).
If desired, you can pour in a small amount of fresh oil and let it drain out to flush out remaining contaminants. This is especially helpful if the oil was very dirty.
-
Replace the drain plug washer and reinstall.
Inspect the copper washer; replace it if it shows signs of wear or deformation. Reinstall the drain plug by hand first, and then use a torque wrench to tighten it to 50 Nm to prevent leaks, overtightening, or stripping.
-
Fill with fresh oil.
Using a clean funnel, add 500ml of Motorex oil (or KTM–approved equivalent) into the oil filler opening. Do not overfill.
-
Reinstall the oil cap and clean up.
Securely reinstall the oil filler cap. Use brake cleaner and rags to remove any spilled oil. Ensure there is no debris or dirt around the cap.
-
Check for leaks.
Start the engine and let it idle for a minute. Check the drain plug and cap area for any signs of leaks. If you see any, shut off the engine and check your torque and washers.
-
Clean up and properly dispose of old oil.
Never dump used oil in the trash, down the drain, or on your property. Take it to a certified recycling center.
Expert Tips
- Double–check the torque: Overtightening the drain plug can strip the threads in the engine case – always use a torque wrench.
- Keep it clean: Clean the area around the drain plug and oil filler cap before opening – dirt inside the engine can cause harm.
- Keep a maintenance log: Record your oil changes with date, hours, and type/amount of oil used for reference.
- Inspect for metal flakes: Some fine metal particles may be normal, but large shards indicate a problem and should be investigated further.
Model–Specific Call–Outs for 2008 KTM 65XC
- This model uses a one–piece drain/filler plug: Always check the copper washer for damage with each change.
- Factory oil spec is 500ml, not 800ml: Some two–stroke KTMs require more oil, but this model is explicitly 500ml. Overfilling can cause leaks and performance issues.
- Check the manual for updates: While this guide aligns with KTM's 2008 recommendations, always reference the latest KTM Owner’s Manual for your bike and region for changes or updates.

Changing your 2008 KTM 65XC’s oil is a straightforward maintenance job any owner can perform with the right tools. This regular service will keep your engine running strong and extend its life, while using the correct oil type and amount ensures the best ride every time.
