  • Torque wrench
  • Oil catch pan
  • Shop towels or clean rags
  • Gloves (recommended)
  • Funnel
  • Replacement oil filter (KTM OEM 77338005100, K&N, or Hi-Flo are all valid options)
  • Replacement O-Ring for oil filter cover (KTM 07703305178)

Before You Begin: 2016 KTM 250XCW Model-Specific Tips

  • Always warm your engine briefly–this allows the oil to flow out easily and brings out more contaminants during draining.
    Be careful: Hot oil can burn. Allow engine to cool if it seems excessively hot after riding.
  • The drain bolt and oil filter cover are both 13mm fasteners, requiring basic tools and minimal force. Over-tightening can strip soft engine cases.
    Consult your owner’s manual for all torque specifications and never exceed manufacturer-recommended values to avoid expensive damage.
  • The 2016 KTM 250XCW has a reusable oil screen filter that should be removed, cleaned, and reinstalled with every oil change. (Don’t skip this step.)

Step-by-Step Oil Change Instructions

  1. Warm Up Engine:
    • Start and idle the bike for 2–3 minutes to bring oil to operating temperature, which helps with drainage.
  2. Remove Oil Fill Cap:
    • Turn the cap counterclockwise and set aside. This lets air in and allows oil to drain out more completely .
  3. Position Your Catch Pan:
    • Place the oil catch pan under the engine before removing any bolts to prevent messy spills.
  4. Remove Drain Bolt:
    • With your 13mm wrench, loosen and remove the main drain bolt. Take care—hot oil will flow out quickly.
    • Be cautious not to drop the drain bolt into the catch pan. Set bolt and washer aside.
  5. Clean and Inspect the Magnetic Drain Plug:
    • Wipe off any debris or metallic shavings from the magnetic end. A small amount is normal; lots of metal indicates potential engine wear .
    • Discard the old crush washer and install a new one to prevent leaks.
  6. Remove, Clean, and Reinstall the Oil Screen:
    • Using needle-nose pliers, gently pull the oil screen from the case.
    • Rinse the screen with brake cleaner and blow it out with compressed air. Inspect for damage—replace if needed .
  7. Remove and Replace the Oil Filter:
    • Remove the oil filter cover (13mm fastener). Pull out the old filter.
    • Install a new O-ring on the cover. Lightly oil the new filter, insert it, and refit the cover hand-tight.
      Do not overtighten.
  8. Reinstall the Drain Bolt and Oil Screen:
    • Reinsert the cleaned oil screen into the case.
    • Screw in the drain bolt by hand first, then use a torque wrench to tighten to 20 Nm / 14.8 ft-lb–do not over-torque .
  9. Add New Oil:
    • Using a funnel, pour in 0.8 liters (27 ounces) of fresh, high-quality 2-stroke transmission oil .
    • Refit the oil fill cap. Snug by hand, then gently with pliers to KTM’s recommended tightness .
  10. Check Oil Level:
    • Set the bike upright and confirm oil is halfway up the sight glass. Top up as needed .
  11. Final Steps:
    • Inspect for leaks at the plug and filter cover.
    • Start the engine, let it idle a minute, switch off, then check the level again and top off if needed.
    • Dispose of waste oil and filter responsibly.

KTM 250XCW Model Call-Outs and Expert Tips

  • Always use genuine KTM filters or reputable aftermarket options. Inferior filters risk oil bypass and damage.
  • Only use oil meant for 2-stroke transmissions–do NOT use engine oil, as it doesn’t provide the necessary clutch protection.
  • Be diligent about torquing bolts to spec, as KTM case material is relatively soft.
  • Clean the area around the drain and filter before opening; dirt in the engine can cause premature wear.
  • Follow the service intervals in your owner’s manual for oil change frequency, especially if racing or riding in harsh conditions.
