  • The oil capacity for the 450SXF Factory Edition is 1.2 liters (1200ml), but always check your manual or the sight glass.
  • This engine uses one oil filter and two oil screens: one on the left side (clutch side, horizontal) and one on the right side (vertical).
  • Never overfill past the site glass's red line or run it lower than halfway up the circle in the sight glass after the motor is warm and level.
  • If the bike has a skid plate, remove it for clean access to drain bolts.

Step-by-Step Oil Change Instructions

  • Warm Up the Engine
    • Start the bike and let it idle for 3-5 minutes to warm the oil. This helps the oil drain more completely and suspends contaminants for removal.
  • Set Up Your Work Area
    • Place the bike on a secure stand. Gather supplies and ensure the bike is upright and level for an accurate oil fill at the end.
    • Lay down absorbent rags or cardboard to protect your floor from spills.
  • Remove the Skid Plate (if equipped)
    • Using the appropriate Allen or Torx wrench, remove the skid plate for unimpeded access to the drain bolts.
  • Drain the Oil
    • Locate both engine drain bolts underneath the engineone directly under the engine (oil pump) and one on the clutch cover side (check your manual or parts fiche if unsure; the 2020 450SXF layout is the same as the '16-'22 models.)
    • Place your drain pan under the bike and loosen the main drain bolt (typically 13mm).
    • Allow all oil to drain. Remove the second (auxiliary) drain bolt to ensure complete drainage.
  • Remove & Clean Oil Screens
    • With the same socket/allen, remove both oil screens: one left/horizontal, one right/vertical. Inspect for debris or metal shavings.
    • Clean each screen with parts cleaner and lint-free rag. Replace if damaged.
  • Replace the Oil Filter
    • Remove the oil filter cover (10mm bolts; right side of engine case). Remove the old filter, noting the direction (the open end faces into the motor).
    • Pre-fill the new oil filter with fresh oil. This reduces startup wear and ensures immediate lubrication upon next start. "Dip" the filter for priming, as many factory riders do.
    • Install the new filter, making certain the O-ring is lubricated and seated correctly.
    • Replace the cover, tightening bolts evenly.
  • Reinstall Screens & Drain Bolts
    • Reinstall both cleaned oil screens.
    • Insert both drain bolts, torque to manufacturer spec (check your manual, typically 15 Nm/11 ft-lbs).
    • Clean off excess oil with a rag to avoid drips.
  • Refill with Oil
    • Remove the oil fill cap on the clutch cover.
    • Using a funnel, pour in fresh 10W-50 up to 1.2L. Do not overfill. Stop just before the max mark if unsure, as you can top off after running the bike.
  • Check for Leaks & Final Oil Level
    • Start the bike and let it idle 1-2 minutes. Shut off and let sit a couple more minutes for oil to settle.
    • Check the oil level in the sight glass on the engine: it should be between halfway and three-quarters up the red circle, never below or above.
    • If needed, add or remove oil to achieve the correct level.
    • Replace the oil fill cap. Wipe down any remaining drips. Reinstall the skid plate if removed.

Pro Tips & 2020 KTM 450SXF Factory Edition Specifics

  • This generation's oil filter orientation is critical. Always insert the open end toward the engine, or you risk top-end starvation and engine failure.
  • Inspect the bolts and threads for damage before reinstalling; overtightening is a common cause of oil leaks in KTM engines.
  • The 2020 450SXF Factory Edition shares its oil change instructions with all 2016-2022 KTM 450/500 SXF, XCF, FE models, as well as Husqvarna and GasGas derivatives.
  • For best results, always use high-quality full synthetic 10W-50 designed for high-performance 4-strokesas Matt from MotoSport recommends.

Final Check
