  • Fresh transmission/gearbox oil (0.8 liters of 15W-50 recommended for many KTM 250 two-strokes, confirm with your owner's manual)

2013 KTM 250XC Oil Change Steps

  1. Warm Up the Engine
    • Start the bike and let it idle for a minute or two to warm the oil. This thins the oil for better draining and helps remove more contaminants.
    • Caution: Oil can get hot. Work safely and allow a short cool down if needed.
  2. Remove the Oil Filler Cap
    • The cap is usually located on the right-hand engine case, near the kickstart lever. Loosen and remove it to help the oil drain freely.
  3. Position the Catch Pan and Remove the Drain Bolt
    • Place your oil drain pan beneath the engine. Using your wrench, carefully remove the oil drain plug found on the bottom of the right engine case.
    • Be ready for a quick stream of oil. Avoid dropping the bolt into the pan.
    • Remove the old crush washer from the bolt; replace it with a new one to prevent leaks upon reinstall.
    • Use this time to inspect the magnetic tip of the drain bolt for excessive metal shavings—some fine debris is normal, but a large amount may indicate internal wear.
  4. Allow Oil to Drain Thoroughly
    • Let the oil drip until only occasional drops emerge. This may take several minutes, but ensures maximum debris removal from the gearbox.
  5. Optional: Oil Filter Replacement
    • Important 250XC Note: Most 2013 KTM 250XC models have a gearbox oil strainer rather than a typical spin-on or cartridge filter.
    • If your specific sub-model (check owner's manual) features an oil screen or external filter, remove and clean/replace it now. Access is typically from the right side of the engine via a small cap held by 8mm bolts.
    • Clean the oil screen with contact cleaner and allow it to dry thoroughly before reinstalling. If equipped with an O-ring, ensure it is pliable and sealed—replace
