Shop parts for a 2014 Suzuki DRZ400SM Dirt Bike.

Changing the oil on your 2014 Suzuki DRZ400SM is a crucial, routine maintenance task that keeps your supermoto running strong on both street and dirt. The DRZ400's oil system is unique with both crankcase and frame drain plugs, so following proper steps is important for a complete oil change. Below, we detail everything you need to know, including tools, parts, step-by-step instructions, and helpful owner-specific call-outs for this model.

Tools and Parts Needed

  • Ratchet
  • 8mm, 12mm, and 17mm sockets
  • Torque wrench
  • Drain pan
  • Gloves and rags (for cleanliness and safety)
  • Funnel
  • OEM or high-quality replacement oil filter
  • 10W-40 motorcycle oil (2 quarts recommended)
  • Replacement washers (drain bolt washers; inspect and replace if needed)

Preparation

  • Warm up the engine for a few minutes to allow the oil to flow out more easily. Do not change the oil when the engine is hot to avoid burns.
  • Place the bike on a stable, level stand for safety and to ensure proper drainage.
  • Refer to your owner's manual for recommended oil type, torque specs, and any additional model-specific info.

Step-by-Step Instructions

  1. Remove the oil filler cap/dipstick from the top of the oil tank/frame. This vents the system and allows oil to drain out more smoothly.
  2. Position your drain pan under the engine and use your 17mm socket to remove the crankcase drain bolt and washer. Allow the oil to fully drain from the crankcase.
  3. Inspect the drain bolt washer for wear or damage. Replace it if necessary. Reinstall the drain bolt and torque it to 15 foot-pounds.
  4. Move the drain pan under the frame. Use your 12mm socket to remove the frame drain bolt and washer. Drain the remaining oil from the frame section.
  5. Again, check the washer and replace if needed. Reinstall the bolt and torque to spec (refer to manual, but typically 15 foot-pounds for DRZ).
  6. Locate and remove the oil filter cover using your 8mm socket. Take out the old oil filter and install the new one, making sure the rubber grommet is properly seated (watch orientation– open end faces out).
  7. Clean the filter cover and mating surface. Reinstall the cover and tighten bolts securely, but don't overtighten (check your manual for exact torque).
  8. Using a funnel, add fresh 10W-40 motorcycle oil through the filler cap. For a filter change, add about 1.8 liters– for oil only, about 1.7 liters.
  9. Reinstall the oil filler cap/dipstick.
  10. Start the engine and let it idle for 2–5 minutes. Shut it off and let oil settle for a couple of minutes. Check the oil level (using the dipstick while the bike is upright without screwing it in) and top up if necessary.
  11. Inspect all bolts and the oil filter area for any leaks. Tighten as needed. Reinstall your skid plate (if equipped).

Important Call-Outs for 2014 DRZ400SM Owners

  • Two Drain Locations: The DRZ400SM features both a crankcase and frame drain, unique to this Suzuki design. Always drain both for a complete oil change.
  • Filter Orientation: The oil filter must be installed with the open end facing the engine—incorrect installation can restrict oil flow and cause engine damage.
  • Recommended Oil Interval: Suzuki recommends your first oil change at 600 miles and every 3,500 miles thereafter. Shorter change intervals are recommended for heavy or dirty riding conditions.
  • Washers: Drain plug washers are prone to wear—replacing them every oil change is good practice for sealing and preventing leaks.
  • Hidden Frame Filter: There is a mesh filter screen inside the oil line at the frame's downtube, which should be inspected and cleaned every few oil changes or according to the service manual. This step is often overlooked by owners.

Wrapping Up

  • Dispose of used oil responsibly at a local recycling center or auto parts store.
  • Record your oil change in your maintenance log.
  • Ride your DRZ400SM with confidence, knowing your engine is protected and ready for adventure.
