Changing the oil in your 2019 KTM 65SX is a crucial part of maintaining engine health and performance. This guide provides a detailed, step-by-step process specifically for this model, along with notes every KTM 65SX owner should know. Proper care and attention will ensure your bike stays in top racing condition and extends the engine's lifespan.

Tools and Materials Needed

  • 13mm wrench or socket (for removing the drain plug)
  • 15mm wrench or socket (may be needed for filler cap on some models)
  • T-handle wrench or ratchet
  • Torque wrench (for correct tightening of the drain plug)
  • Oil catch pan
  • Funnel
  • Cleaning rag
  • New crush washer or O-ring (recommended with every change)
  • Engine oil (consult your KTM manual, typical capacity is 0.3 liters or 300 ml for the 65SX)
  • Gloves (optional but advised)

Step-By-Step Instructions

  1. Warm up the engine.
    • Let the bike run for a few minutes until it reaches normal operating temperature. This helps the oil drain out faster and more completely.
  2. Position the bike securely.
    • Place the motorcycle on a stable stand on level ground to prevent tipping.
    • Ensure you have easy access to the left side of the engine, just behind the shifter where the drain plug is located.
  3. Remove the filler cap.
    • Twist off or unbolt the oil filler cap located on top of the engine. This allows oil to drain more freely by letting air in.
  4. Clean around the drain plug.
    • Wipe the area to prevent dirt or debris from entering the crankcase when the plug is removed.
  5. Position the oil catch pan.
    • Slide a suitable container directly under the drain plug to catch all used oil.
      Environmental tip: Never allow oil to spill onto the ground; always recycle used oil properly.
  6. Remove the drain plug.
    • Use your 13mm wrench or socket to carefully loosen and remove the drain plug. Avoid dropping the plug into the oil pan.
    • Allow the oil to fully drain. Take your time; this can take several minutes.
  7. Inspect and clean drain plug.
    • Clean any metal shavings off the magnetic tip of the drain plug (a small amount is normal).
    • Inspect the crush washer or O-ring and replace if worn or damaged to prevent leaks.
  8. Replace and tighten the drain plug.
    • Reinstall the cleaned drain plug with its new washer or O-ring.
    • Use a torque wrench to tighten the plug to 20 Nm (14.8 ft-lb) as specified by KTM.
  9. Refill with new oil.
    • Using a funnel, pour in 300 ml (0.3 liters) of manufacturer-recommended gear oil or engine oil. Always check your manual for the correct fluid type and level.
    • Fill slowly, checking for overflow.
    • Do not overfill beyond the recommended capacity, as excess oil can cause engine issues.
  10. Replace and secure the filler cap.
    • Screw the filler cap on tightly. If your model has an O-ring, inspect and replace if worn.
    • If indicated by KTM, use pliers to gently snug the cap so it cannot vibrate loose during riding.
  11. Start engine and check for leaks.
    • Start the engine, let it run for a minute, then shut it off and check for any oil leaks around the drain plug and filler cap.
    • Recheck the oil level and top up if needed (do this after the oil has re-settled).

KTM 65SX Year-Specific Notes (2019 Model)

  • For the 2019 KTM 65SX, KTM specifies 300 ml (0.3 liters) of gear oil for an oil change. Overfilling or underfilling can affect clutch and transmission performance.
  • The drain plug is located on the left side behind the shifter. Use care when accessing and cleaning this spot.
  • Always use fresh crush washers or O-rings to prevent seepage—these are inexpensive insurance against leaks.
  • KTM recommends specific gear oil types; using oils not recommended by KTM could affect shifting and clutch function.
  • Do not dispose of oil carelessly. Bring it to an authorized collection location.

Maintenance Tips

  • Change oil every 5-10 hours of operation, or after every race for optimal engine and transmission health.
  • Inspect the magnetic drain plug for any excessive metal debris, which could indicate abnormal engine or transmission wear.
  • Check your manual for any updates or changes in service intervals.
