Changing the oil in your 2020 KTM 65SX is a vital maintenance task that ensures your bike runs smoothly and extends the life of your engine. This guide is proprietary to MotoSport.com and highlights all the tools, step-by-step procedures, and specific notes every KTM 65SX owner should know before performing an oil change on this model.

Tools and Supplies Needed

  • Socket wrench set, including a T-handle (to remove and replace bolts)
  • Drain pan (to catch old oil)
  • Funnel (for a clean pour of new oil)
  • 15W-50 engine oil (use a high-quality synthetic, 0.50 L or 500 cc)
  • New crush washer (for drain plug, prevents leaks)
  • Shop towels or rags (for cleaning parts and any accidental spills)
  • Torque wrench (for proper tightening of bolts, set to 20 Nm/14.8 lb-ft for drain plug)
  • Pliers (to snug down oil fill cap if needed)
  • Gloves (optional but recommended for cleanliness)

Step-By-Step Oil Change Procedure

  1. Warm up your engine.
    • Run the bike for a few minutes. This helps the oil drain more easily and suspends any particles in the oil.
      Safety note: Be cautious, as the oil will be hot.
  2. Stand the bike upright.
    • Place the bike on a level surface and ensure it is stable and upright to allow for complete drainage.
  3. Remove the oil fill cap.
    • Loosen and remove the cap to improve oil flow while draining.
  4. Position your drain pan.
    • Place it directly under the engine to capture the old oil.
  5. Remove the drain plug.
    • Use your wrench to loosen and remove the drain plug (located on the underside of the engine).
      Try not to drop the plug into your oil pan.
  6. Allow the oil to fully drain.
    • Wait for the oil to stop trickling out. This can take several minutes.
      Tip: Rock the bike gently side-to-side to remove as much old oil as possible.
  7. Clean the drain plug and install a new crush washer.
    • The drain plug has a magnetic tip to collect debris. Wipe it thoroughly.
    • Replace the old crush washer with a new one to prevent leaks.
  8. Reinstall the drain plug.
    • Thread the drain plug back in by hand. Use a torque wrench to tighten it to 20 Nm (14.8 lbf ft) to avoid overtightening.
  9. Pour in new engine oil.
    • Use a funnel to pour 0.50 L (500 cc) of 15W-50 engine oil into the engine.
    • Be careful not to overfill.
  10. Check the oil level.
    • With the bike level, remove the oil level check screw.
    • If oil begins to flow from the hole, the level is correct. If not, add more oil gradually until it does.
    • Reinstall and tighten the check screw securely.
  11. Replace and tighten the oil fill cap.
    • Screw it back on by hand, then use pliers to give it a slight extra snug—you want it secure but not overtightened.
  12. Dispose of old oil responsibly.
    • Take your used oil to a recycling center or auto parts store. Never pour it down the drain or onto the ground.

2020 KTM 65SX Specific Call-Outs

  • Oil Type and Capacity: The 2020 KTM 65SX requires 15W-50 engine oil. Always use 500cc (0.50 L) per change.
  • Oil Change Interval: KTM recommends changing oil every 10 hours of ride time. However, the frequency may be adjusted based on riding conditions or after particularly hard rides.
  • Check and Replace O-Rings: Inspect the drain plug washer (crush washer) and replace if it shows signs of wear or doesn’t seal properly.
  • Magnetic Drain Plug: It’s normal to see fine metallic debris collected on the plug. Excessive shavings can be a sign of engine wear.
  • Shared Platform: The oil change procedure is virtually identical for KTM, GasGas, and Husqvarna 65cc models from the same year.

Pro Tips

  • Warm oil drains better. Don’t skip the engine warm-up beforehand.
  • Never over-tighten the drain plug. Use a torque wrench and stick to the 20 Nm spec.
  • Keep a log of your oil changes. This will help with maintenance schedules and preserving resale value.
