Here's a comprehensive, proprietary guide from MotoSport.com that walks you through the process with all the tools, steps, and unique callouts specific to this make, model, and year.

Tools & Supplies You’ll Need

  • 10mm socket and ratchet (for oil filter cover)
  • 17mm socket (for drain bolt)
  • Torque wrench (20.5 lb-ft/28 N·m for drain bolt)
  • Drain pan (to catch old oil)
  • Funnel (for refilling)
  • Measuring cup (for accurate oil volume)
  • Rubber or nitrile gloves
  • Paper towels or clean rags
  • Replacement oil filter (optional, but recommended for every second or third change)
  • API SF or SG rated oil, SAE 10W-40 (0.9 US quarts/0.85L when not changing the filter; 1.0 US quart/0.9L with filter change)

Before You Begin

  • Make sure the engine is warm, not hot. Let it idle for 5–10 minutes so the oil drains thoroughly but wait for the engine/exhaust to cool if it is too hot to avoid burns .
  • Work in a well-ventilated area.
  • Keep children and pets away from new/used oil and used filters to avoid health hazards .
  • Always recycle or properly dispose of old oil and filters.

Step-By-Step Oil Change Instructions

  1. Warm up the Motorcycle:
    • Start your DRZ125L and let it idle for 5–10 minutes, then turn off the engine and make sure it’s stable on its side stand .
  2. Remove the Oil Filler Cap:
    • Remove the oil filler cap. This lets oil drain easily by allowing air flow .
  3. Set Up Your Drain Pan:
    • Place a drain pan under the motor. Ensure you’re on level ground to maximize the old oil drainage .
  4. Remove the Drain Bolt:
    • Using the 17mm socket, loosen the main oil drain bolt under the engine while applying upward pressure (to avoid splashing).
    • Let the oil drain fully. Standing your bike vertically helps remove more old oil .
    • Check the crush washer/gasket and replace if worn.
  5. Remove the Oil Filter (Optional but Recommended):
    • Using a 10mm socket, remove the cover on the oil filter housing.
    • Gently pull out the old oil filter; watch for remaining oil in the housing.
    • Wipe out residual oil and debris with a clean towel, being careful not to dislodge the rubber seal. Always ensure the O-ring/gasket stays in place .
    • Install the new oil filter.
  6. Reinstall Drain Bolt & Oil Filter Cover:
    • Wrap up by cleaning the threads and reinstalling the drain bolt. Torque it to 20.5 lb-ft (28 N·m) .
    • Reinstall the filter cover and torque evenly to manufacturer specs.
  7. Add New Oil:
    • Using a funnel, pour in new 10W-40 oil. For just an oil change, fill to 0.85L (0.9 US quarts). If replacing the filter, use 0.9L (1.0 US quart) .
    • Double-check for leaks. Reinstall the oil filler cap.
  8. Prime and Check Oil Level:
    • Start the engine and let it idle for 2–3 minutes. Turn it off and wait several minutes for oil to settle.
    • With the bike standing vertically, check the level using the dipstick. Add oil as needed, but do not overfill .
  9. Clean Up:
    • Dispose of old oil and the filter at a recycling center.
    • Wipe off any spilled oil on the engine or frame.

Special Call-Outs for the 2007 Suzuki DRZ125L

  • Never overtighten the drain bolt. Use a torque wrench for the correct spec: 20.5 lb-ft (28 N·m) .
  • Check that the drain bolt washer/gasket isn’t worn out to prevent future leaks .
  • The DRZ125L’s oil filter does not require replacement every oil change, but swapping it every second change is recommended for optimal engine life .
