Shop parts for a 2004 Suzuki DRZ110 Dirt Bike.

Changing the oil in your 2004 Suzuki DRZ110 is one of the most important maintenance tasks to keep your engine running smoothly and reliably. This DIY guide from MotoSport.com provides step-by-step instructions, lists the recommended tools, and highlights essential tips specific to the DRZ110 platform (which is mechanically identical to the Kawasaki KLX110 for these model years).

Tools and Materials Needed

  • 3/8” ratchet with extension
  • 8mm, 12mm, and 17mm sockets
  • T40 Torx bit (if your skid plate uses Torx bolts)
  • Oil drain pan
  • Rags and gloves
  • Torque wrench
  • Funnel
  • Replacement oil (refer to your owner’s manual for the correct type and capacity—generally about 1 liter of 10W-40 four-stroke motorcycle oil is recommended)
  • Replacement crush washer for the drain bolt (optional but recommended)

Steps to Change the Oil

  • Warm Up the Engine
    • Start the bike and let it idle for 1-2 minutes. This helps the oil flow out easily.
  • Remove the Skid Plate
    • Use the 8mm socket to remove two bolts on each side of the skid plate.
    • Use the 12mm socket for the bolts behind the skid plate and set the skid plate aside.
    • Caution: If you just ran the bike, the exhaust and engine may be hot—work carefully to avoid burns.
  • Remove the Oil Fill Cap
    • Unscrew the cap on top of the right engine case. This allows the oil to drain quicker by preventing suction.
  • Drain the Old Oil
    • Place your drain pan under the engine. Use the 17mm socket to remove the drain bolt under the left side of the engine case.
    • Let all old oil drain out. Inspect the drain plug and washer for wear—replace the washer if needed.
  • Reinstall the Drain Bolt
    • Clean the drain bolt and install a new crush washer if you have one, then hand-tighten the bolt back into the case. Use your torque wrench to finish tightening to the specification in your service manual (typically around 14 ft-lbs).
  • Add New Oil
    • Insert a funnel into the fill hole and pour in the recommended amount of clean four-stroke motorcycle oil (usually about 1 liter). Check your owner’s manual for the exact amount.
    • Let the oil settle for a minute, then check the level through the sight glass or dipstick. Add oil as necessary until the level lines up with the “Full” mark.
  • Start the Engine and Check for Leaks
    • Start the bike and let it run for about a minute. Shut it off and let it sit for another minute, then check the oil level again and inspect for any leaks around the drain plug.
    • Top off the oil if needed.
  • Reinstall the Skid Plate
    • Use your sockets and Torx bit to reinstall the skid plate securely to protect the underside of your engine.

Model-Specific Callouts for the 2004 Suzuki DRZ110

  • Identical Procedure to Kawasaki KLX110:
    • The Suzuki DRZ110 uses nearly all the same engine parts as the Kawasaki KLX110 from the same era, so oil change procedures, filter (if equipped), and torque specs are directly compatible.
  • Oil Filter Replacement:
    • The DRZ110 does not have a traditional spin-on or cartridge oil filter; just a strainer in the crankcase. This only needs cleaning every few oil changes and is not required at every oil change interval. Refer to your owner’s manual for strainer service intervals.
  • Oil Capacity:
    • Approximately 1 liter (1.1 US qt). Always use the sight glass to double-check after filling.
  • Crush Washer:
    • Replacing the drain bolt crush washer is optional each time, but it is good practice to avoid leaks.

Tips for Best Results

  • Always dispose of used oil responsibly—use a local recycling facility.
  • Check your oil after every ride for level and appearance, especially if you ride hard or under dusty conditions.
  • Change your oil every 6 months or 25 hours of riding, whichever comes first. If the oil looks dirty in the sight glass, replace it sooner.
  • Be mindful not to overtighten bolts; stripped drain plug threads are a common and expensive mistake.

Conclusion

Keeping your 2004 Suzuki DRZ110 maintained with regular oil changes is the simplest way to ensure years of reliable riding.
