Specific Call-Outs for the 2022 KTM 85SX

  • Oil capacity: 0.50 L (500cc, 0.53 qt.) of gear oil

  • Check oil level: After filling, use the level check screw to ensure proper fill

  • Recommended oil: Use manufacturer-recommended 2-stroke transmission oil
  • Drain plug torque: Tighten to 20 Nm (14.8 ft-lb) after oil change

Step-By-Step Instructions

  1. Warm Up the Engine
    • Start the bike and let it idle for a few minutes to warm up the oil. This helps the old oil drain out completely.
    • Turn off the engine and wait a minute to avoid hot surfaces.
  2. Remove Skid Plate (if equipped)
    • If your 85SX is fitted with a skid plate, remove it to access the drain plug.
  3. Set Up Your Workspace
    • Position the bike in an upright, stable position on a stand, with the oil catch pan below the engine.
  4. Remove the Oil Fill Cap
    • Unscrew the oil fill cap located on the right side of the engine. This step allows the oil to drain more freely

      .
  5. Remove the Drain Plug
    • Using the 17mm wrench, carefully loosen and remove the drain plug at the bottom of the crankcase.
    • Let all the old oil drain into the pan. Be cautious, as the oil may be hot

      .
  6. Inspect and Clean the Drain Plug
    • While the oil drains, inspect and clean the magnetic drain plug. Remove any metal shavings–some are normal. Also install a new crush washer if available to prevent leaks

      .
  7. Reinstall the Drain Plug
    • Once oil is fully drained, reinstall the drain plug with a new crush washer. Use a torque wrench to tighten it to 20 Nm (14.8 ft-lb)

      .
  8. Add New Oil
    • Using the funnel, pour 0.50 L (500cc/0.53 qt.) of gear oil into the fill hole

      .
    • Do not overfill; use a graduated measuring cup for precision

      .
  9. Reinstall the Oil Fill Cap
    • Replace and hand-tighten the oil fill cap. For extra security, snug it down with pliers if necessary, as KTM recommends

      .
  10. Check the Oil Level
    • Start the engine and let it run briefly, then shut it off and keep the bike upright.
    • Remove the oil level check screw on the side of the engine. Oil should just begin to weep from this hole. If not, add a small amount more until it does

      .
    • Reinstall the check screw.
  11. Dispose of Old Oil Responsibly
    • Take the used oil to a recycling center or auto parts store that accepts used oil. Never dump oil on the ground.

Extra Tips for the 2022 KTM 85SX Owner

  • Double-check the oil type: always use a high-quality two-stroke transmission oil suitable for motocross bikes.
  • Avoid over-tightening the drain bolt to prevent stripping the threads—use a torque wrench to verify proper Torque.
  • Inspect the oil for large metal fragments, which could indicate transmission wear requiring further inspection.
  • Change the oil every 5–10 hours of riding, or more frequently for race use.

Maintaining clean and properly filled oil in your 2022 KTM 85SX is a key step in protecting your bike's transmission and ensuring top-notch performance on every ride.
