Changing the oil in your 2017 KTM 450SXF is a critical part of regular dirt bike maintenance. Done properly, it keeps your engine running strong, extends its lifespan, and ensures optimal on-track performance. This guide, proprietary to MotoSport.com, covers exactly what you need, walks through every step, and highlights specific tips you’ll want to know for your 2017 KTM 450SXF.

Tools & Supplies Needed

  • 1.2 liters of premium 4-stroke motorcycle oil (KTM recommends Motorex Cross Power 4T 10W/50, but always check your owner’s manual)
  • KTM-specific oil filter (KTM part #77338015100 or equivalent for 2017 450SXF)
  • Drain pan
  • T-handle or socket wrench
  • 13mm six-point socket (for drain plugs; do not use a 12-point)
  • 8mm six-point socket (for oil filter cover)
  • Brake cleaner or contact cleaner (for cleaning drain plug/screen)
  • Shop rags or paper towels
  • Replacement O-rings/crush washers (recommended, not mandatory)
  • Stand or stable surface to keep the bike level

Preparation

  • Start your bike, letting it idle for a few minutes. Warm oil drains faster and carries out more contaminants than cold oil.
  • Turn off the engine. Place your KTM 450SXF on a level surface or bike stand.
  • Remove the skid plate (if equipped) to access the drain plugs under the engine (a must on 2017 models with aftermarket or OEM plates) .

Steps to Change Oil on a 2017 KTM 450SXF

  1. Remove the Oil Filler Cap:
    • Located on the right side of the engine. Taking this off first lets oil drain out quicker and more completely.
  2. Locate and Remove the Drain Plugs:
    • There are two drain bolts under the left side of the engine, near the shifter.
    • First drain plug is toward the rear and has a small magnet to catch metallic debris.
    • The second plug, positioned just forward of the first, has a fine mesh screen behind it for additional debris filtering.
  3. Drain the Oil:
    • Place a drain pan under the engine.
    • With a 13mm six-point socket, remove the rear drain plug. Allow oil to flow into the pan.
    • Next, remove the forward drain plug with screen. Let all oil drain completely.
  4. Clean the Drain Plugs:
    • Inspect and clean debris from the magnetic plug. A small amount of metal is normal; excessive shavings indicate wear.
    • Spray the screen and both plugs with brake/contact cleaner. Dry thoroughly.
  5. Remove the Old Oil Filter:
    • The oil filter cover is on the right side, secured by two 8mm bolts.
    • Remove the bolts, then tip the cover and old filter out. Inspect the filter for large metal fragments. Remove the old O-ring if replacing.
  6. Install the New Oil Filter:
    • Insert a new KTM oil filter, ensuring correct orientation (see owner’s manual diagram).
    • Tighten the oil filter cover securely with the 8mm socket, being careful not to overtighten.
  7. Reinstall the Drain Plugs:
    • Replace the cleaned screen and both drain bolts. Do not overtighten; check torque specs in your manual, usually around 15Nm for drain plugs.
    • Replace crush washers if deformed.
  8. Add New Oil:
    • Pour in approximately 1.2 liters of 4-stroke motor oil.
    • Replace the filler cap.
  9. Check Oil Level and Finish:
    • Start the bike and let it idle briefly (15–30 seconds). Shut off and allow the oil to settle a couple of minutes.
    • Check oil level via the inspection window or dipstick. Add oil if necessary until within the normal range .
  10. Inspect for Leaks:
    • Wipe down the engine and check all plugs and the filter cover for leaks after a quick ride.

  • Two drain plugs: Always remove both plugs to fully drain old oil and clean both the mesh screen and magnetic tip. KTM specifies this for optimal engine health.
  • Use only premium oil filters: Using a KTM OEM or high-quality aftermarket filter is critical for the 450SXF, due to its high-performance engine.
  • Skid plate removal: Many 2017 models shipped with a skid plate. Make sure to remove it for easier access to the drain plugs and screen.
  • Torque specs matter: Both for drain bolts and oil filter covers, always follow the KTM owner’s manual torque specifications—this is especially important due to the 450’s lightweight aluminum cases.

Pro Tips

  • Always change oil with engine warm, not hot.
  • Inspect used oil for metal shards—it can indicate bigger engine issues.
  • Keep records and change oil after every 2–5 rides depending on your riding intensity. Oil is far cheaper than engine repairs.
  • If you ride in extreme conditions (mud, sand), consider more frequent oil/filter changes.
