Tools and Supplies Needed

  • 8mm socket or T-handle (for oil filter cover bolts)
  • 13mm socket (for drain plug bolt)
  • Torque wrench
  • Drain pan
  • Funnel
  • Shop rags
  • Contact cleaner
  • New oil filter (KTM OEM #77338005100 or equivalent)
  • Filter cover O-ring (KTM OEM #07703305178 – optional, inspect and replace as needed)
  • Replacement crush washer (optional, inspect and replace as needed)
  • Oil screen (optional) (clean and inspect, replace if damaged or excessively dirty)
  • KTM recommended engine oil (synthetic 10W-50, 1.20L with filter change)
  • Pliers (optional, for circlip or oil filter removal)

Preparation

  • Run the engine for 2-3 minutes to warm up the oil. This helps ensure the oil flows out smoothly, taking contaminants with it.
  • Place your bike on a stand, ensuring it is upright and secure.
  • Remove the skid plate if installed, for better access to the drain plugs if necessary.

Oil Change Steps

  1. Remove the Drain Plugs
    • Position your drain pan beneath the engine.
    • Using your 13mm socket, loosen and remove both the main and secondary oil drain bolts to ensure a complete drain.
    • Watch out for hot oil.
    • Remove and inspect both crush washers. Replace if damaged or worn for optimal sealing.
  2. Remove and Clean the Oil Screens
    • There are two oil screens: one on the left and one on the right side of the engine. Pull them out with pliers if necessary.
    • Inspect for debris or metal shavings, which could indicate internal engine issues.
    • Clean the screens thoroughly with contact cleaner and a rag.
  3. Replace or Clean Oil Filter
    • Locate the oil filter cap on the right side of the engine, secured with two 8mm bolts. Remove the bolts and cap.
    • Remove the old oil filter. Clean the filter cavity with a shop rag and contact cleaner.
    • Lightly oil the new filter before installing it. Insert the new filter, ensuring correct orientation (the open side faces out).
    • Inspect the filter cover O-ring. Replace if cracked or damaged.
    • Reinstall the filter cap and torque the bolts to KTM—s specifications (usually 10 Nm, always check your service manual).
  4. Reinstall Drain Plugs and Oil Screens
    • Reinstall both clean oil screens back into their original positions.
    • Install both drain bolts with new or inspected crush washers.
    • Tighten the primary drain bolt to 20 Nm (14.8 ft-lbs) and secondary (screen cap) to 15 Nm (11 ft-lbs).
  5. Refill With Fresh Oil
    • Use a funnel to help pour in 1.20 liters of KTM-recommended oil for the 2020 KTM 250SXF Factory Edition (when also replacing the filter).
    • Replace and torque the oil fill cap.
  6. Initial Check and Top Off
    • Start the engine and let it run for 2-3 minutes to circulate the oil.
    • Turn off the bike and wait a few minutes to let the oil settle.
    • Check the oil through the sight glass. The correct oil level should be just above halfway with the bike held upright and level.
    • If needed, add small amounts of oil and repeat until the proper level is reached.
  7. Final Inspection
    • Inspect for any leaks around the filter cover, drain bolts, and fill cap.
    • Reinstall the skid plate if removed.
    • Wipe off any drips or spills, and properly dispose of old oil and filter at your local recycling facility.

2020 KTM 250SXF Factory Edition-Specific Callouts

  • This model uses two oil screens and a single oil filter—ensure both oil screens are removed, cleaned, and reinstalled for each oil change.
