Model-Specific Call-outs – 2020 KTM 450 EXC-F

  • This model uses two drain plugs; both should be removed to ensure a complete drain of old oil.
  • If equipped, remove the skid plate for easier access to the drain plugs and oil screens.
  • Always verify the oil capacity; while 1,200 ml is standard, check your manual for your specific variant.
  • Visually inspect the oil screens when removing for debris or engine wear indicators.
  • Only use a 6-point socket on drain plugs to prevent rounding the bolts.

Step-by-Step Oil Change Procedure

  1. Warm Up the Engine
    • Start the bike and let it idle for 3-5 minutes. Warm oil flows and drains better, aiding in a complete oil change.
  2. Remove the Skid Plate
    • If your bike has a skid plate, remove it now using the appropriate tool.
    • Set it aside for easy reinstallation later.
  3. Remove Both Drain Plugs
    • Locate the two drain plugs (13mm bolts) beneath the engine. Position your drain pan underneath.
    • Loosen and remove both bolts, allowing all oil to fully drain out.
    • Be careful; the oil may be hot. Inspect bolts for any metal shavings or debris, which could indicate internal wear.
  4. Clean and Inspect Oil Screens
    • Each drain plug typically holds an oil screen. Remove these carefully and inspect them for debris.
    • Clean the screens with a lint-free rag and inspect for signs of excessive material, which could mean abnormal engine wear.
  5. Replace/Inspect the Oil Filter
    • Locate the oil filter housing (usually two 8mm bolts).
    • Remove the cover and slide the old filter out. Replace it with a new KTM-approved filter.
    • Be sure to lightly prime the new filter by dipping it in clean engine oil before installation.
    • Reinstall the cover and torque the bolts evenly to avoid leaks.
  6. Re-install Oil Screens and Drain Plugs
    • Reinsert the clean oil screens and lightly coat the drain plug threads with fresh oil or thread sealer if specified.
    • Hand-tighten, then torque to factory specification (refer to your owner's manual for precise values).
  7. Add Fresh Oil
    • Remove the oil fill cap on the right side of the bike.
    • Using a funnel, pour in 1,200 ml of fresh engine oil. Always confirm the correct type and quantity per your owner's manual.
    • Reinstall the oil fill cap securely.
  8. Run the Engine & Check Oil Level
    • Start the engine and let it run for about 3 minutes. Shut it off and allow oil to settle for 1-2 minutes.
    • Check the oil sight glass; the level should be between half and three-quarters full while the bike is upright and level.
    • Add oil if necessary to reach the correct level.
  9. Final Checks and Clean Up
    • Inspect for leaks around the oil filter housing, drain plugs, and fill cap.
    • Clean up any residual oil on the engine or frame with a rag.
    • Reinstall the skid plate, if equipped.
    • Safely dispose of used oil and filter at an approved recycling facility.

Pro Tips and Additional Reminders

  • Change the oil after every 10 hours of riding or every 2-3 rides for optimal engine health, especially under hard use, racing, or extreme conditions.
  • Consider keeping a record of oil changes and note any metal fragments or irregularities found during the process.
  • An oil change is much less expensive than engine repairs – stay consistent.
