Special KTM 250XC-W Model Callouts

  • The drain plug is located at the rear of the engine block, facing the back wheel.
  • There are three oil filters: two mesh (one below the gear lever behind a bolt, one underneath behind the sump guard), and one paper filter (above the left footpeg).
  • Replace O-rings and crush washers every oil change to prevent leaks; O-rings on these bikes can perish quickly.
  • Always use the correct torque for all bolts and the drain plug: 20 Nm (14.8 ft-lbs).
  • KTM recommends 0.8 liters of 15W-50 oil for this model.

Step-by-Step Instructions

  1. Warm Up the Engine (Optional):
    • Start and idle the engine for a few minutes to warm the oil. Warm oil will drain faster and help remove more contaminants. Be careful, as it will be hot when draining.
  2. Prepare the Bike and Work Area:
    • Place the bike upright on a stable stand.
    • Ensure you have all tools and supplies ready.
  3. Remove the Oil Fill Cap:
    • Loosening the oil fill cap on the clutch side will allow air in and help the oil drain smoothly.
  4. Locate and Remove the Drain Plug:
    • Using the 13mm socket, remove the sump drain plug (at the rear of the engine block, facing the back wheel); let the oil drain completely into your catch pan.
    • Be careful not to drop the drain plug into the oil pan.
  5. Service the Oil Filters:
    • Remove the left side paper filter cover (above the footpeg) and replace the filter (HiFlo HF655 or equivalent).
    • Remove the two mesh filters:
      • One is behind a bolt below the gear lever. Use the 8mm Allen key.
      • The other is underneath the engine, behind the sump guard.
    • Clean both mesh filters thoroughly with solvent and let them dry before reinstalling.
    • Replace O-rings and crush washers on all covers/plugs as needed.
  6. Inspect the Magnetic Drain Plug:
    • Wipe off any metallic debris from the magnetic drain plug. A little accumulation is normal.
  7. Replace Crush Washers and Reinstall Drain Plug:
    • Use a new copper crush washer to prevent leaks.
    • Install the drain plug and finger-tighten, then torque to 20 Nm (14.8 ft-lbs).
  8. Install New Oil Filter(s):
    • Slide a new paper filter into place above the footpeg and reinstall the cover, ensuring the new O-ring sits properly.
    • Reinstall both mesh filters and ensure all O-rings are in good shape or replaced as needed.
    • Tighten all covers to the specified torque.
  9. Add Fresh Engine Oil:
    • Insert a funnel into the oil fill port. Pour in 0.8 liters of the recommended 15W-50 oil.
    • Allow a few moments for the oil to settle. Do not overfill.
  10. Reinstall Oil Fill Cap:
    • Replace the oil fill cap and snug it down slightly with a pair of pliers, as KTM recommends, to prevent it from coming loose unexpectedly.
  11. Check for Leaks and Final Inspection:
    • Start the engine and let it idle for a couple minutes. Look for any leaks around the drain plug and filter covers.
    • Stop the engine, wait a minute, then check the oil level with the bike vertical and add oil if necessary to reach the correct mark.
  12. Dispose of Old Oil Properly:
    • Take the used oil to a recycling center; never pour it down a drain.
