Tools and Supplies Needed

  • Socket wrench set (preferably with 8mm–17mm sockets)
  • Torque wrench (to properly tighten the drain bolt)
  • Oil drain pan
  • Funnel
  • Clean rags or paper towels
  • Parts cleaning brush
  • New crush washer (recommended to replace the old one on the drain bolt)
  • Engine/gear oil (recommended: high-quality synthetic 2-stroke gear oil; capacity: 0.74 quarts or approximately 700 ml)

  • Disposable gloves (for cleanliness and protection)

Step-by-Step Instructions

1. Warm Up the Engine

  • Start the bike and let it idle for 2–3 minutes. This warms the oil, making it easier to drain completely and suspend contaminants.

2. Prepare the Work Area

  • Turn off the bike and place it securely on a stand or level surface.
  • Position your oil drain pan under the drain bolt, which is located at the lowest point on the crankcase/gearbox area.

3. Remove the Drain Plug

  • Using the appropriate socket or box-end wrench, remove the oil drain plug. Be cautious as warm oil will flow out quickly.

  • Let the oil drain fully; tilting the bike gently can help evacuate all oil.
  • If equipped, clean any magnetic debris off the drain plug’s magnet.

  • Check and replace the crush washer if needed to prevent future leaks.

4. Clean and Inspect

  • Wipe down the drain bolt and plug threads with a clean rag.
  • Take the opportunity to inspect the old oil for any metal shavings or abnormal residue, which could indicate internal wear.

5. Reinstall the Drain Plug

  • Thread the cleaned drain bolt back into the case by hand, then torque it to factory specification (refer to your owner’s manual for exact torque, usually between 10–15 Nm for most European 125s).

6. Fill With Fresh Oil

  • Remove the oil fill cap, usually located on the right side of the case above the clutch cover.
  • With a funnel, add 700 ml (0.74 quarts) of recommended synthetic gear oil—do not overfill.

  • Wipe any spills and re-install the fill cap securely.

7. Check Oil Level

  • The 2015 TE125 typically uses a viewing glass or check bolt to confirm proper fill. If using a check bolt, remove it briefly to confirm oil just begins to spill from this port.

8. Final Inspection

  • Start the engine and let it run for 1–2 minutes. Inspect around the drain bolt and fill cap for any leaks.
  • Shut off the bike and recheck the oil level; top off if necessary.
