Regularly changing the oil in your 2011 Kawasaki KLX110 is one of the most critical maintenance steps to keep your dirt bike in peak condition. Fresh oil helps lubricate internal engine components, keeping your ride smooth and extending engine life. If you want to save money on labor and get hands-on with your bike, follow this detailed MotoSport.com proprietary guide for a complete oil change.

Tools and Materials Needed

  • 3/8” ratchet and extension
  • 8mm socket
  • 12mm socket
  • 17mm socket
  • Torque wrench
  • Oil drain pan
  • Funnel
  • 1 liter of 10W-40 motorcycle oil (The KLX110 uses about 0.9 liters if not replacing the filter, use 1 liter to be safe)
  • Clean rags
  • Gloves (optional, but recommended)

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    Start your KLX110 and let it idle for a couple of minutes. Warm oil drains more easily and removes more contaminants from the crankcase.
    Tip: Do not run too long. Shut off the bike after 2–3 minutes to avoid burns from hot components.
  2. Remove the Skid Plate
    - Use the 8mm socket to remove the bolts on each side of the skid plate.
    - Remove the two 12mm bolts located behind the skid plate.
    - Slide the skid plate off and set it aside.
    Model-specific callout: The KLX110 has engine access protection that must come off for a clean oil change. Be cautious as exhaust parts may be hot after warming the engine.
  3. Remove the Oil Fill Cap
    Loosen and remove the oil fill cap on the right side of the engine. This ensures a smooth flow during draining and prevents air lock.
    Be cautious: removing the cap after warming the engine could expose you to hot vapor.
  4. Drain the Oil
    - Place your oil drain pan underneath the engine.
    - Use the 17mm socket to remove the drain bolt located at the bottom of the engine.
    - Allow all the oil to fully drain.
    - Inspect the drain bolt and washer for metal shavings or damage—replace if necessary.
    Model-specific callout: The KLX110 has a simple horizontal drain plug; no awkward access is required, making this process straightforward.
  5. Replace the Drain Bolt
    After the oil has drained, clean the drain bolt, then reinstall and hand-tighten it.
    - Use your torque wrench to tighten the drain bolt to the manufacturer’s spec (generally 15 ft-lbs; always check your service manual for the latest spec).
  6. Oil Filter (If Applicable)
    - If you’re changing the oil filter, remove it now, following your service manual direction. Replace the old filter with a new one (such as OEM or K&N KN-112).
    - Lubricate the new filter’s O-ring with a little fresh oil before installing.
    - Tighten per the filter manufacturer’s directions.
    You do not have to change the oil filter at every oil change for the KLX110, but it’s recommended every other change or as indicated in your manual.
  7. Refill the Engine with Oil
    - Insert a funnel in the oil fill hole.
    - Pour in 0.9–1.0 liter of 10W-40 motorcycle oil.
    - If you replaced the filter, use closer to 1.0L; otherwise 0.9L should be sufficient.
    - Reinstall the oil fill cap and clean up any drips.
  8. Check Oil Level
    - Start the bike and let it idle for 2–3 minutes to circulate the new oil.
    - Turn off the bike and let it rest on level ground for a couple minutes.
    - Check the sight glass (located on the clutch cover) to ensure oil level is between the upper and lower marks.
    - Add oil if needed, a little at a time, until the level is correct.
    Model-specific callout: Always keep the KLX110 upright (not on side stand) for an accurate level reading.
  9. Reinstall the Skid Plate
    Replace the skid plate and torque all bolts to specification using the correct sequence and your torque wrench.

Specific Notes for 2011 Kawasaki KLX110 Owners

  • The standard drain bolt and oil fill cap locations are unchanged across most KLX110 years, including 2011. Tools and drain point access are the same as later models.
  • The 2011 model does not have an oil filter element; it uses a mesh screen inside the engine. If you want to clean it, you must remove the right side cover, which is not required for every oil change and can be left for more comprehensive servicing.
  • The oil capacity is the same as modern models: 0.9L (0.95 quart) without filter maintenance, 1.0L (1.05 quart) if cleaning the internal screen.

Disposal and Final Tips

  • Dispose of the used oil at an approved recycling center—never dump oil on the ground or in drains.
  • Double-check torque on all fasteners, and wipe off any drips for a professional finish.
  • Keep a maintenance log including the date, hours, and type of oil used for your next oil change.

By changing the oil as described, you ensure your 2011 Kawasaki KLX110 runs strong for seasons to come. For parts, oil change kits, and factory spec reference, always trust MotoSport.com for expert support and fast shipping.
