Shop parts for a 2007 Suzuki DRZ400S Dirt Bike.

Regular oil changes are vital for the longevity and performance of your 2007 Suzuki DRZ400SM. This dual sport bike uses a dry-sump oil system and features both a primary oil filter and a frame screen filter. Below, you’ll find a detailed, step-by-step oil change guide specific to your DRZ400SM, trusted by MotoSport.com for maximum reliability and clarity.

Tools and Supplies Needed

  • Ratchet
  • 8mm, 12mm, and 17mm sockets
  • Torque wrench (for precise tightening of bolts)
  • Drain pan
  • Funnel
  • New oil filter (OEM or high-quality aftermarket)
  • Fresh oil (10W-40 motorcycle oil, 2 quarts)
  • Replacement crush washers (if needed)
  • Clean rags or shop towels
  • Gloves and safety glasses (for safety and cleanliness)

Step-by-Step Instructions

  • Warm up the engine for a few minutes to allow the oil to flow more easily. Then, shut it off and place your bike securely on a stand.
  • Remove the oil filler cap/dipstick from the top of the frame, just behind the handlebars. This helps the oil drain more efficiently by allowing air into the system

    .
  • Position a drain pan underneath the crankcase. Using the 17mm socket, remove the crankcase drain bolt and washer. Allow the oil to drain completely into the pan

    .
  • Inspect the drain bolt washer, and replace it if worn out or damaged. Reinstall the drain bolt and washer once draining is complete, and torque it to 15 foot-pounds for a proper seal

    .
  • Next, move the drain pan under the lower frame and use the 12mm socket to remove the frame drain bolt and washer. Again, let all oil drain fully. Inspect, replace, and properly torque this bolt as well

    .
  • Remove the oil filter (found on the right side of the engine, behind a three-bolt cover). Be prepared for residual oil to leak out when pulling the filter. Clean the filter housing area with a rag

    .
  • Install the new oil filter, applying a bit of fresh oil to the rubber gasket for a proper seal. Reinstall the filter cover and tighten the bolts evenly according to the manufacturer’s torque specification.
  • Special call-out for the DRZ400SM: Locate and clean the small mesh oil screen inside the frame (sometimes called the “frame filter screen”). Remove the cap (typically just below the oil filler) with the right tool, extract the mesh screen, clean off any debris or metal shavings, and reinstall

    .
  • Replace the skid plate if you removed it for access

    .
  • Add fresh oil: Use a funnel to pour 1.8 liters (1.9 quarts) of 10W-40 motorcycle oil if replacing the filter–1.7 liters (1.8 quarts) if not changing the filter. Use the dipstick to check the oil level, then screw the dipstick back into place

    .
  • Start the engine and let it idle for a few minutes. Watch for oil leaks. Turn off the bike, wait a few minutes for the oil to settle, then check the oil level once more and top off as needed

    .
  • Check for leaks around the oil filter cover and both drain bolts. If all is well, the oil change is complete. Dispose of the old oil and filter responsibly.

Model-Specific Tips and Cautions for the 2007 Suzuki DRZ400SM

  • The dry-sump system on the DRZ400SM means you have both a crankcase drain and a frame drain bolt—both must be removed to fully drain the oil

    .
  • Cleaning the mesh frame oil screen is important but often overlooked. This helps prevent debris circulation and potential engine damage

    .
  • Don’t over-tighten the drain bolts or filter cover bolts—use a torque wrench.
  • Oil changes should be performed after the first 600 miles and every 3,500 miles thereafter, as per Suzuki recommendations; more frequent changes are advised if you ride in harsh conditions

    .
  • Always use motorcycle-specific oil (JASO MA-rated) to maintain proper clutch and engine performance.

Final Thoughts

Changing the oil on your 2007 Suzuki DRZ400SM is a straightforward job that maximizes performance and engine life. Attention to detail–like cleaning the frame oil screen and using the correct oil quantity–sets your maintenance apart and keeps your dirt bike adventure-ready.
