Tools & Parts You'll Need

  • 8mm and 13mm sockets or wrenches (for drain and filter cover bolts)
  • Torque wrench (critical for reassembly to manufacturer spec)
  • Oil drain pan (to collect used oil)
  • Clean rags or shop towels
  • Funnel
  • Fresh engine oil (KTM recommends Motorex Cross Power 4T 10W-50 or an equivalent)
  • New oil filter (OEM: 77338005100 or equivalent aftermarket)
  • New oil filter cover O-ring (recommended: 07703305178)
  • New drain plug/crush washer (recommended for best seal)
  • Contact cleaner (optional, for cleanup)

  • Secure the bike on a stand and ensure stability. Place the oil pan under the bike.

Step-by-Step Oil Change Process

  1. Remove the Skid Plate (if applicable):
    • Some models may have a skid plate protecting the underside. Remove it with appropriate tools if needed.
  2. Drain the Oil:
    • Locate the oil drain bolt (right side, bottom of engine case).
    • Using the 13mm socket, carefully remove the drain bolt and let the oil drain completely into the pan.
    • Remove the oil fill cap to allow oil to drain faster by venting the system.
    • Inspect the drain bolt’s crush washer; replace it for a proper seal.
  3. Remove and Clean Oil Screens:
    • The 2016 KTM 250SXF has two oil screens: one near the drain plug and another on the clutch side.
    • Remove both using the 8mm socket. Clean them thoroughly with a rag and brake/contact cleaner. Check for debris or metal particles (indicative of engine wear).
    • Reinstall cleaned screens with care.
  4. Remove and Replace Oil Filter:
    • Locate the oil filter cover on the right side of the engine.
    • Remove the bolts with an 8mm socket. Carefully remove the cover and old filter.
    • Clean the filter cover thoroughly and inspect/replace the O-ring.
    • Lubricate the new filter’s O-ring with a little fresh oil and install the new filter.
    • Reinstall the cover and torque bolts to spec (refer to your manual; typically around 10 Nm).
  5. Install the Drain Bolt:
    • Once oil is fully drained and screens reinstalled, reinstall the drain bolt with a new crush washer.
    • Torque the drain bolt as per the KTM service manual specifications (do not overtighten to avoid stripping the case) (generally around 15 Nm).
  6. Add New Oil:
    • With a funnel, pour in approximately 1 liter of recommended oil. The sight glass on
