Regular oil changes are essential to keep your 2015 Kawasaki KLX110 running strong and extend its engine life. Use this robust, step-by-step guide to perform your own oil change like a pro.

Tools and Supplies Needed

  • 3/8th” ratchet and extension
  • 8mm, 12mm, and 17mm sockets
  • Torque wrench
  • Oil drain pan
  • New engine oil – 10W-40 motorcycle oil (1 liter)
  • Replacement crush washer for drain bolt (recommended)
  • Rags or shop towels
  • Optional: Oil filter (KLX110 does not have a traditional replaceable oil filter, but check your owner's manual and inspect the oil screen if desired)

KLX110-Specific Call-Outs

  • This model does not use a replaceable spin-on oil filter.
  • The oil drain bolt is 17mm and located at the bottom of the crankcase.
  • Proper oil capacity is approximately 1 liter (0.9 liters if not inspecting the screen).
  • Be cautious when working around the exhaust; it gets hot quickly if the engine is warmed up.
  • The oil level check is via a sight glass on the right side – check with the bike upright and level.

Step-by-Step Oil Change Process

  • Warm Up the Engine
    Run the engine for 2–3 minutes to warm the oil. This helps the old oil drain out more completely.
    Note: If you already removed the skid plate before warming up the engine, avoid touching the exhaust as it will be hot.
  • Remove Skid Plate
    Use your 8mm and 12mm sockets to remove the 8mm bolts on each side and two 12mm bolts behind the skid plate. Remove the skid plate to access the drain bolt.
  • Remove the Oil Fill Cap
    On the right side of the engine, unscrew the oil fill cap. This allows oil to vent and drain more freely.
  • Drain the Old Oil
    Place your oil drain pan under the engine. Using the 17mm socket, remove the drain bolt and allow the oil to fully drain.
    Inspect and replace the crush washer if it looks damaged or flattened.
  • Reinstall the Drain Bolt
    Reinstall the drain bolt with a new or cleaned crush washer. Tighten it snugly by hand, then use a torque wrench to torque it to the manufacturer’s spec (typically 18 ft-lbs; check your manual to confirm).
  • Add New Oil
    Using a funnel, add 1 liter of 10W-40 four-stroke motorcycle oil through the oil fill opening. If you did not clean the oil screen, only add 0.9 liter.
  • Reinstall the Oil Fill Cap
    Wipe the cap clean and verify the sealing surface is free of debris. Reinstall and tighten the fill cap.
  • Check the Oil Level
    Start the engine and let it idle for 3 minutes. Shut off and let sit for a couple of minutes so the oil can settle. Check the oil sight glass on the right side of the engine with the bike upright on level ground—the oil should be between the upper and lower marks.
    Add oil a little at a time if needed. Do not overfill.
  • Clean Up and Reinstall the Skid Plate
    Wipe off any oil drips from the engine, reinstall the skid plate, and torque the bolts evenly.
  • Dispose of Old Oil Responsibly
    Pour the used oil into a suitable container and bring it to a recycling center or auto parts store for disposal.

Pro Tips for 2015 Kawasaki KLX110 Owners

  • Use only motorcycle-specific oil like 10W-40 formulated for wet clutches – automotive oil can cause clutch issues over time.
  • If you ride in muddy or dusty conditions, change your oil more frequently—every 10 hours of riding or at least once per season.
  • The KLX110’s oil screen is a mesh filter on the drain plug; it’s a good idea to clean it every few changes by removing and rinsing it with a solvent.
  • Always double-check the oil level after a short ride, as some air pockets may work out and the oil level may drop slightly.

Fast FAQ

  • Oil Capacity: 1.0L (0.9L if just draining)
  • Recommended Oil Type: 10W-40, motorcycle-specific
  • No replaceable oil filter on this model; only a mesh screen
  • Oil Check: Use the right-side sight glass, upright bike, on level ground
