2026 KLX110L Oil Change Intervals & Important Notes

  • Change oil every 6 months or 50 hours of use–whichever comes first.
  • Replace the oil filter every other oil change.
  • Inspect the oil in the sight glass regularly; replace if it looks dark or dirty.
  • No major mechanical changes are expected for the 2026 model vs. 2025–2023, but always check your owner's manual for any new recommendations.

Step-by-Step Guide

  1. Preparation
    • Start your bike and let it idle for 2–3 minutes. This warms the oil, allowing it to drain easier.
    • Place the bike on a stable, flat surface. Use a bike stand for easier access to the drain bolt.
    • Gather all your tools and supplies so you can work efficiently.
  2. Remove Skid Plate (if equipped)
    • Use an 8mm, 10mm, or 12mm socket (or T40 Torx bit, depending on hardware) to remove the bolts securing the skid plate. Place fasteners in a safe spot.
    • Note: Left side bolts may be longer than right side bolts. Keep track for reassembly.
  3. Drain Old Oil
    • Locate the Oil Drain Plug under the engine.
    • Position your drain pan beneath the plug.
    • Using a 17mm socket, carefully loosen and remove the drain bolt. Let all oil drain completely.
    • Remove the oil filler cap (on the right side of the engine) to allow for smoother flow.
    • Inspect and replace the crush washer on the drain bolt as needed.
  4. Replace Oil Filter (every other change)
    • Locate the oil filter cover (typically secured by 8mm or 10mm bolts) on the right-hand side of the engine.
    • Carefully remove the bolts and the cover. Take out the old filter, noting its direction.
    • Clean the cover with a rag and contact cleaner.
    • Install the new filter, ensuring it's oriented correctly (spring side out, if present).
    • Reinstall cover and torque bolts to specification (check owner's manual).
  5. Install Drain Plug
    • Wipe down area around the drain hole with a clean rag.
    • Install the drain plug with the new crush washer. Tighten securely with the 17mm socket, being careful not to overtighten (typically about 18 ft-lb–verify in your owner's manual).
  6. Add New Oil
    • Using a funnel, pour in 1.1 US quarts/1 liter of 10W-40 engine oil.
    • Check the oil level at the sight glass on the right side of the crankcase. With the bike upright, the oil should be just below the top mark of the glass.
    • Install the oil filler cap securely.
  7. Final Steps
    • Start the engine and let it idle for a few minutes. Check for any leaks around the drain plug and filter.
    • Shut off the engine. Wait 1–2 minutes and recheck the oil level, topping off if necessary.
    • Reinstall the skid plate, ensuring correct bolt placement (remember which bolts were longer).
    • Clean up any spilled oil and dispose of old oil and filter properly.

2026 Kawasaki KLX110L Model-Specific Call-Outs

  • The oil change process for the 2026 KLX110L closely follows previous KLX110L models and does not require unique procedures based on current information. Owners should always reference the supplied service manual for any last-minute engineering updates or minor part/bolt size changes that Kawasaki may implement for 2026.
  • Crush washers are a common source of leaks. Always inspect and replace if in doubt.
  • If your skid plate has Torx bolts (more common on aftermarket or newer models), be sure to use the correct T40 Torx bit for removal and installation.

Pro Tips from MotoSport.com

  • Never overtighten drain or filter mounting bolts–aluminum threads are easily stripped.
  • Record the date and hours of each oil change to stay on a regular maintenance schedule.
  • Warming up the engine slightly prior to draining the oil significantly improves the removal of debris and contaminants.

Stay on top of your oil changes, and your Kawasaki KLX110L will deliver years of fun and reliable riding.
