Tools and Materials Needed

  • 10mm and 13mm sockets or T-handle wrenches (for drain and fill bolts)
  • Torque wrench (to ensure proper reassembly torque)
  • Drain pan
  • Funnel
  • Clean rags or shop towels
  • Replacement oil filter (KTM OEM part #77338005100 or aftermarket equivalent)
  • Filter cover O-ring (recommended: KTM #07703305178)
  • Replacement crush washer (recommended, especially if the current one is damaged)
  • 1 liter of 10w50 high-quality motorcycle oil (see owner's manual for recommended brands)
  • Gloves (optional, but recommended for a cleaner job)
  • Contact cleaner or brake cleaner (to clean up any spills)

Preparation Steps

  • Start the bike and let the engine idle for 3–5 minutes to heat up the oil. This helps with more complete drainage.
  • Place the bike on a stand and make sure it's secure and upright.
  • Clean the area around the oil fill and drain bolts thoroughly to prevent debris from entering the engine during oil change.
    “Make sure there's like no dirt around it because you don't want to just shove a bunch of dirt into your motor…”

Step-by-Step Oil Change Instructions

  1. Remove the Oil Drain Bolts and Drain the Oil
    • Place your oil drain pan directly below the drain plug(s) on the bottom of the engine.
    • Using your socket or T-handle, remove the drain plug. Allow the oil to drain completely.
    • On the 2019 KTM 250XCF, there are two oil screen plugs (one on each side of the engine) that should be removed and cleaned individually to capture any engine debris. Do not skip this.
  2. Clean and Inspect Oil Screens
    • Remove the oil screens from the engine (often tucked behind an external plug).
    • Thoroughly clean the oil screens with a clean rag and inspect for metal shavings or excessive debris, which could indicate internal engine wear.
    • Reinstall the screens after cleaning.
  3. Remove and Replace the Oil Filter
    • Locate and remove the oil filter cover (left side of engine).
    • Pry out the old oil filter. Inspect the filter for metal shavings or foreign debris.
    • Replace the O-ring if necessary, and ensure it's seated correctly. Lubricate the new O-ring with a bit of fresh oil.
    • Install the new oil filter in the correct orientation. KTM filters are directional–match the orientation to the old one or consult your manual.
    • Reinstall the filter cover and torque the bolts to manufacturer specifications (do not overtighten, KTM casings are soft and can strip out easily.)
  4. Install New Crush Washer and Reinstall Drain Plug
    • Install a new crush washer onto the drain bolt(s) to prevent leaks.
    • Torque the drain bolt(s) to the spec found in your owner's manual (do not overtighten–typically 10–13 ft-lbs, but always verify).
  5. Add New Oil
    • Remove the oil fill cap.
    • Using a funnel, pour in approximately 1 liter of 10w50 motorcycle oil.
    • Check the oil level in the sight glass with the bike upright–the oil should sit just above the halfway mark.
  6. Final Checks
    • Reinstall the oil fill cap.
    • Wipe down any spilled oil with a rag and use contact/brake cleaner if needed.
    • Start the engine and allow it to idle for 1–2 minutes. Shut off the bike and check for leaks at the drain plugs and filter cover.
    • Once the engine has sat for a few minutes, recheck the oil level in the sight glass with the bike level, and top off as necessary.

Important Call-Outs for the 2019 KTM 250XCF

  • Always clean around the oil fill and drain plugs before you remove them to prevent any debris from entering the engine.
  • Don't overtighten bolts or plugs—KTM engine casings are relatively soft. Torque to factory specifications only.
  • Clean the oil screens every oil change—these are your early warning for potential engine issues and maintain oil flow.
  • Check your owner's manual for torque specs, oil capacity, and other model-specific details.
  • Use the correct oil filter orientation—installing backwards can compromise engine lubrication.
  • Run the bike and check for leaks and correct oil level before your next ride.
