Keeping fresh oil in your 2016 KTM 450SXF Factory Edition is one of the most important maintenance tasks to keep your bike running strong. This how-to, proprietary to MotoSport.com, covers all the steps, tools, KTM-specific pointers, and tech details you need to perform a thorough oil change and keep your machine ready for the track or trail.

Tools and Materials Needed

  • Drain pan (wide, low-profile works best under the frame)
  • Ratchet and sockets (8mm, 13mm needed for drain bolts and oil filter cover)
  • Torque wrench (for correct assembly torque specification)
  • Circlip pliers (helpful for removing the oil filter, if needed)
  • Clean rags or shop towels
  • Parts cleaning brush (for cleaning the oil screen)
  • Funnel (to prevent oil spillage when pouring new oil)
  • Motorex 10W-50 full synthetic oil (1.2 liters)
  • OEM oil filter (KTM specific)
  • Replacement O-rings (for oil filter cover and drain bolts if needed)
  • New crush washer (for the main drain bolt)
  • Contact cleaner (optional, for cleaning parts and surfaces)

Step-by-Step Oil Change Procedure

  • Warm up the engine. Start the bike and let it idle for several minutes. This helps the oil flow out more easily and drains more thoroughly.
    Tip: Always change oil with the engine warm for best results.
  • Remove the oil filler cap. This is found on the right side of the engine case. Removing the cap will help oil drain more freely through the bottom.
    This step is frequently overlooked, but it makes the draining process much quicker and more thorough.
  • Place your drain pan under the bike. Make sure it is positioned to catch all the old oil.
  • Remove drain bolt(s) and oil screen cover:
    • Main drain bolt: Located below the shifter on the left side of the engine – use a 13mm socket.
    • Oil screen bolt: In front of the main drain, use a socket to remove this bolt (typically also 13mm).
    • Bottom drain bolt: There is a secondary drain bolt at the very bottom of the motor. Remove this to ensure a full drain

      .
  • Pull the oil screens. With the drain bolts removed, gently extract the oil screens from their respective housings. Clean these screens with contact cleaner and a brush, inspecting for trapped debris, and replace if damaged

    .
  • Remove the oil filter. Loosen and remove the two 8mm bolts holding the oil filter cover in place (right side of the engine). Wiggle the cover free, noting the orientation of the O-ring. Carefully pull the oil filter out; circlip pliers can help if it feels stuck. Clean the cavity with a rag and ensure no debris remains

    .
  • Pre-oil and install the new filter. Before installing, fill the new filter with a bit of fresh oil. Insert it gently into the housing, ensuring a tight fit. Inspect the O-ring and replace if needed, then reinstall the filter cover and bolts, tightening evenly

    .
  • Inspect, clean, and reinstall plugs/screens.
    • Replace crush washers on drain bolts.
    • Push the cleaned oil screen back into place until you feel it “click” in.
    • Torque specs:
      • Drain bolts 20 Nm (14.8 ft.lbs)
      • Oil screen cap 15 Nm (11 ft.lbs)
  • Refill with new oil. Using a funnel, pour in 1.2 liters of Motorex 10W-50 full synthetic oil. KTM recommends this specific viscosity for best durability and clutch performance

    .
  • Reinstall oil filler cap. Hand-tighten, then snug gently with pliers to avoid accidental loosening from vibration or boot contact

    .
  • Start and check oil level. Start the engine and let it run for a minute to circulate the oil. Shut it off and let the oil settle for a few minutes. Check the level in the sight glass:
    • Oil should register just above the halfway mark in the round sight glass – never above the red line

      .
  • Check for leaks. With the motor idling, look for any oil seepage around drain bolts, filter cap, and the filler cap. Shut off and address any leaks before riding.

2016 KTM 450SXF Factory Edition Specific Call-Outs

  • Oil quantity: 1.2 liters with filter change, as verified for the 2016–2022 generation

    .
  • Filter orientation matters. Always install the oil filter with the correct side facing the engine as per KTM’s marking.
  • Drain bolt torque: The aluminum case can strip threads if over-torqued. Always use a torque wrench.
  • O-rings and crush washers: Inspect every time. Pre-2019 models, including 2016, use similar drain bolt, screen, and O-ring configuration.
  • Sight glass levels: The oil should be just above halfway when the bike is upright and level. Overfilling leads to increased crankcase pressure – do not exceed recommended level.

Final Tips from MotoSport.com

  • Change oil after every 5–10 hours of hard riding, or sooner for racing conditions.
  • Always use new filters and washers for each change to ensure maximum engine life.
  • Dispose of used oil responsibly.

Maintain your KTM with pride and ride with confidence: proper oil changes are the best insurance for your engine’s long life.
