Steps to Change the Oil in Your KTM 250SXF Factory Edition

  1. Warm up your engine
    • Start and run the bike for a few minutes to get the oil warm. This helps it drain faster and more thoroughly.
  2. Remove the skid plate (if installed)
    • This exposes the drain plugs and oil filter area for easier access (2016–2022 models use the same oil change method).
  3. Remove both drain plugs
    • The 2017 KTM 250SXF has two oil drain bolts: one for the main sump and one for the oil screen (typically 8mm or 13mm heads).
    • Place your drain pan underneath and remove both bolts, allowing all oil to drain out fully.
    • Inspect and clean the oil screen located behind one of the plugs. Remove, clean with brake/contact cleaner, and reinstall when finished.
  4. Replace the crush washers
    • Always use new crush washers when reinstalling your drain bolts to ensure a leak-free seal.
  5. Install and torque the drain bolts
    • Reinstall the cleaned oil screen and both drain bolts. Use your torque wrench to tighten them to the factory specifications (consult manual for specifics, usually 12 Nm for drain plugs).
  6. Replace the oil filter
    • Locate the oil filter cover on the right side of the engine.
    • Remove the bolts, then take off the cover and pull out the old filter. Inspect and replace the O-ring on the cover if worn.
    • Install the new OEM filter (KTM #77338005100) in the correct direction.
    • Lightly oil the O-ring, replace the cover, and torque the bolts per the manual (usually 8 Nm). Do not overtighten.
  7. Add new oil
    • Use a funnel to pour in the correct quantity of fresh oil; for the 2017 KTM 250SXF, this is roughly 1 liter (950 mL to 1,050 mL)–check your manual for the exact amount.
    • Replace and hand-tighten the oil filler cap.
  8. Prime and check oil pressure
    • To avoid a dry start, many techs recommend cranking the motor with the kill switch held down to prime the new oil filter before starting.
  9. Start the engine and check for leaks
    • Briefly start the engine and let it idle for a minute to circulate the oil. Shut it off and inspect the drain plugs and filter cover for any leaks.
    • Let the bike sit upright for a minute, then check the oil sight glass or dipstick, and adjust the oil level if necessary.
  10. Clean up and reinstall the skid plate
    • Wipe away any oil residue with contact cleaner and a towel. Reinstall your skid plate if removed.

Model-Specific Call-Outs for the 2017 KTM 250SXF Factory Edition

  • Two drain bolts and oil screen: KTM's four-stroke engines from 2016 onward (including 2017 250SXF) require removal of both drain bolts and cleaning of the washable oil screen for a complete oil change.
  • Precise bolt torque: Overtightening can strip the soft aluminum cases. Always use a torque wrench and adhere to KTM's manual specifications (e.g., typically 12 Nm for drain bolts, 8 Nm for filter cover bolts).
  • Correct oil type: Use only motorcycle-specific, high-performance synthetic oil (such as Motorex Cross Power 4T 10W-50), not automotive oil, to protect the clutch and gearbox.
  • Filter orientation: Install the oil filter in the same direction as removed (open side/facing out in most models). Reference manual photos if unsure.

When to Change Oil

  • Every 10–15 hours of ride time, or sooner in severe conditions. Change oil more often if you ride hard, race, or in harsh environments.

Final Tips

  • Keep tracking maintenance in a log.
  • Dispose of all used oil and filters responsibly.
  • If unsure or inexperienced, consult your local KTM dealer or a MotoSport.com professional for service help.

Properly performed, this oil change provides peace of mind and reliability every time you hit the track or trails on your 2017 KTM 250SXF Factory Edition.
