  • Clean rags and gloves
  • Replacement oil filters:

    • Long oil filter: KTM part #8580380051
  • 2 liters (1.8L required) of 10W-50 full synthetic motorcycle oil (KTM PowerParts or Motorex Cross Power recommended)

Before You Start: Model-Specific Call-Outs

  • The 2016 KTM 690 Enduro R uses two oil filters of different sizes plus two oil screens. Both must be serviced for a proper oil change.
  • You will need to remove the skid plate for access. It is secured with two bolts in the front and slides off easily.
  • The engine takes just under 2 liters (1.8L) of oil. Do not overfill.
  • Two separate drain plugs and screens mean thorough draining is essential for proper oil replacement.

Step-by-Step Oil Change Instructions

  1. Warm up the bike
    • Idle the engine for several minutes to ensure the oil is warm (not hot), which helps it flow out more completely.
      Tip: A short neighborhood ride is perfect.
  2. Remove the skid plate
    • Use the socket or Allen wrench to remove the two bolts holding the skid plate. Set aside safely.
  3. Position your oil pan
    • Place your oil catch pan beneath the engine to catch draining oil.
  4. Remove the drain plugs and oil screens
    • There are two drain bolts underneath–one at the sump (engine bottom), one on the side. Both have large mesh oil screens.
    • Loosen and remove both, allowing oil to drain completely.
    • Note: Inspect both screens for debris or metal flecks; clean screens carefully with a rag and inspect for damage.
  5. Replace or clean the oil screens
    • Rinse or wipe the screens with a lint-free rag and inspect closely.
    • Ensure O-rings are in good condition–replace if needed.
  6. Remove and replace both oil filters
    • There are two filters: a short filter (side of engine) and a long one (bottom near the sump).
    • Unscrew both covers; remove old filters and O-rings.
      Lubricate new O-rings with a dab of fresh oil before installing.
    • Insert new filters (short and long, in their respective locations–for part numbers and orientation, see above).
  7. Reinstall oil screens and drain plugs
    • Double check screens are cleaned and properly seated.
    • Install new crush washers (if included/recommended).
    • Reinstall and torque drain plugs and oil screen bolts to factory specifications (typically 15–20 Nm, but consult your manual for exact torque).
  8. Refill with fresh oil
    • With a funnel, pour in 1.8L of 10W-50 synthetic oil.
    • Do not overfill–this can affect engine performance and damage seals.
    • Install the filler cap securely.
  9. Start engine and check for leaks
    • Before replacing the skid plate, start the engine and let it idle for a minute.
    • Check around drain plugs and filter covers for oil leaks.
    • Shut off, let sit a minute, and check the oil level with the bike upright using the sight glass or dipstick.
    • Top up if necessary.
  10. Reinstall skid plate
    • Once you're leak-free and oil is at the correct level, reinstall the skid plate securely.

Tips and Pro Tricks for the 2016 KTM 690 Enduro R

  • Document each oil change—write mileage and date on a receipt or log for warranty and maintenance records.
  • Use only high-quality filters and O-rings—inferior parts are a common source of future leaks.
  • Proper warm-up ensures dirty oil is suspended and will drain out, rather than settling at the bottom of the engine.
  • Be patient when draining. Let the bike sit level for several minutes after plugs are removed for maximum oil removal.

Common Mistakes to Avoid

  • Forgetting to clean or replace both oil screens–essential for engine longevity on the KTM 690 Enduro R.
  • Over-tightening oil drain plugs or forgetting new crush washers, which can cause stripped threads or leaks.
  • Neglecting to warm the engine before draining, resulting in old oil being left behind.

Final Thoughts

Performing a thorough oil change on your 2016 KTM 690 Enduro R takes about 45 minutes and helps prolong the life of your high-performance engine. Keeping careful records, using OEM or quality parts, and following the above steps ensures your bike is ready for anything the trail or road throws at it.
