Tools and Supplies Needed

  • Oil drain pan
  • 8mm, 13mm and 17mm sockets/wrenches
  • Torque wrench
  • Socket extension
  • Flathead screwdriver or T25 Torx (for the skid plate, if equipped)
  • Needle-nose pliers
  • Clean rags
  • KTM-specific oil change kit (includes two oil filters, O-rings, copper crush washers)
  • Appropriate engine oil: Motorex Cross Power 4T 10W-50 or equivalent (about 1.7 litres)
  • Funnel
  • Gloves (recommended)

Steps to Change the Oil

  1. Warm Up the Engine
    Start and idle your bike for a few minutes. Warm oil drains faster and carries away more contaminants.
    Tip: Do not overheat. Five minutes is usually sufficient.
  2. Stabilize the Bike
    Place the bike on a flat, stable surface and use the side stand. Keep the bike as level as possible for maximum oil drainage.
    Adventure note: Use a paddock stand if you own one for added security and stability.
  3. Remove the Skid Plate (if installed)
    Use the correct tool (often 8mm or T25 Torx) to remove the front two bolts, then slide the skid plate off. Set aside.
    Be gentle to avoid stripping threads.
  4. Locate and Loosen Both Drain Bolts
    - The main sump drain bolt is on the bottom of the engine case.
    - The frame drain bolt (also referred to as the oil tank drain) is on the frame's right, behind the bash plate.
    Use a 13mm or 17mm wrench depending on your model year. Loosen both but don't remove yet.
    Caution: Both bolts have crush washers that need replacing.
  5. Drain the Oil
    Place your oil pan under the engine. Remove both drain bolts and let the oil drain completely.
    Allow several minutes for thorough draining.
  6. Remove and Replace Oil Filters and Clean Oil Screens
    • There are two oil filters: one on the left side (behind a small cover), and one on the right (vertical, near the forward downtube).
    • Remove both filter covers using the correct socket or Allen/hex key.
    • Extract old filters with pliers and insert new filters from the KTM oil kit.
    • Replace O-rings and clean both machined filter cover surfaces.
    • There are also two oil screens:
      • The front screen by the frame downtube; unscrew and clean with brake cleaner, inspect for metal debris.
      • The rear screen under the engine case; remove and clean as above.
    • Replace copper washers on the screens and reinstall finger-tight, then torque to spec.
  7. Reinstall Drain Bolts and Covers
    Use new crush washers, tighten all bolts by hand, then torque to KTM specs (consult your manual, usually between 15–20 Nm).
  8. Add New Oil
    Remove the oil fill cap (right side of the engine, near the clutch cover). Insert a funnel and pour in about 1.6 litres of Motorex 10W-50 oil.
    Replace the cap.
  9. Prime Oil System
    Briefly start the engine (do not rev) and run for 30 seconds to circulate oil. Turn off, let sit for a minute, then check the oil level using the sight glass or dipstick.
    Add oil as needed to reach the proper level—do not overfill.
  10. Check for Leaks
    Inspect all drain plugs, filters, and covers for seepage. Tighten further (within torque spec) if needed.
    Reinstall the skid plate.
  11. Dispose of Used Oil Responsibly
    Bring used oil to a recycling center or authorized service shop.

Specific Owner Call-Outs for the 2020 KTM 690 Enduro R

  • Dual Filters and Screens: The KTM 690 Enduro R features two oil filters and two screens. Skipping either risks engine damage.
    Don't just drain and refill—always replace both filters and clean both screens.
    Some older KTM models only use one, so be wary of using generic guides from other bikes.
  • Drain Bolt Position: Ensure you drain from both the sump and frame bolts. Failure to do so leaves old oil trapped.
    This is a known issue with rushed or incomplete services and can void your warranty.
  • Crush Washers and O-rings: Reuse of these parts can cause leaks. Always use the new ones supplied in your KTM or aftermarket kit.
    KTM recommends fresh washers/O-rings every oil change for proper sealing.
  • Oil Capacity: The correct fill is usually just under 1.7 litres (1.6 to 1.7 L). Overfilling your 690 Enduro R can cause foaming and reduced lubrication.
    Double-check with dipstick after running for a minute as the system self-primes.
  • Filter Orientation: Insert the filters in the correct direction—consult packaging or manual for correct orientation, as reversing can block oil flow.
  • Skid Plate Fit: The stock (or aftermarket) skid plate must be reinstalled securely—missing bolts or stripped threads are common errors after maintenance.

Common Mistakes to Avoid

  • Skipping filters or screens—essential for longevity and warranty compliance.
  • Forgetting to replace crush washers—leads to oil leaks and contamination.
  • Tightening drain bolts excessively—stripping threads is expensive to repair.
  • Not verifying oil level after cycling engine—the bike's dry-sump design needs proper priming for accurate level checks.

Final Thoughts

Changing the oil yourself on the 2020 KTM 690 Enduro R is straightforward and offers an immediate boost to performance and reliability. Follow this guide and your KTM 690 Enduro R will reward you mile after mile with smooth, reliable power and extended engine life.
