Important Model-Specific Notes for 2022 Suzuki DR-Z125L Owners

  • The oil fill cap can be tricky to remove–using the handle of a pliers helps if it’s stuck.
  • Be sure you are removing the correct drain plug under the engine, not other bolts in the area.
  • Allow the engine and exhaust to fully cool to avoid burns, but always warm up the bike before changing the oil to ensure thorough draining.

Step-by-Step Guide to Changing Oil in a DR-Z125L

  • Warm the Engine
    Run the bike for 5 to 10 minutes to bring the engine up to temperature. This thins the oil for more effective draining.
  • Position the Bike Safely
    Place the motorcycle upright on a stable surface or use the side stand as outlined in the owner’s manual.
  • Remove the Oil Filler Cap
    Twist out the oil filler cap to allow air in and speed up draining. If it feels stuck, carefully use the handle of a pliers for leverage.
  • Drain the Oil
    Place an oil catch pan underneath the engine. Use a 21mm socket to carefully loosen and remove the oil drain plug and washer.
    Allow the oil to drain completely while holding the motorcycle vertically for best results.
  • Remove and Replace the Oil Filter
    Locate the oil filter cover (held by three 10mm bolts). Remove these bolts, take out the old filter, and clean the mounting surface.
    Install the new filter, ensuring correct orientation, and torque the bolts evenly.
  • Inspect and Reinstall Drain Plug
    Clean the drain plug and inspect the sealing washer. Replace the washer if it shows signs of wear or damage.
    Reinstall the drain plug by hand to avoid cross-threading. Finish tightening with a torque wrench set to 20.5 lb-ft.
  • Add New Oil
    Pour in 950mL (1 quart) of recommended 10W-40 oil. Check for oil recommendations in your owner’s manual or on the case.
    Replace the filler cap securely.
  • Start the Engine and Check for Leaks
    Run the engine for a minute, shut it off, and inspect the drain plug and filter cover for leaks. Tighten if necessary after checking.
  • Check Oil Level
    After a few minutes (bike off), read the oil level using the dipstick or sight glass (if equipped). Add more oil if needed but avoid overfilling.
  • Dispose of Old Oil and Filter Properly
    Take used oil and filters to a local recycling facility. Never dispose of oil in household trash or drains.

Additional Tips and Safety Notes

  • Wear gloves and protect skin–prolonged oil contact can irritate skin, and old oil is carcinogenic with repeated exposure.
  • Double-check torque specs–overtightening can strip aluminum threads in the engine case.
  • Keep oil and parts clean–foreign debris can affect engine longevity.
