Shop parts for a 2014 Suzuki DRZ125L Dirt Bike.

Maintaining your 2014 Suzuki DRZ125L air filter is crucial for optimal power, throttle response, & engine life. This proprietary MotoSport guide will walk you through step-by-step instructions tailored to your dirt bike’s design and quirks.

Key Notes for the 2014 Suzuki DRZ125L Owner

  • The DRZ125L uses a foam air filter designed for frequent cleaning in off-road conditions.
  • Only one side panel needs removing for air filter access, simplifying maintenance and saving time compared to other full-size dirt bikes.
  • Ensure plastics and heat shield are intact—the exhaust runs near the airbox, so inspect for melted plastic which could impact filter fit and longevity.

Tools & Supplies Needed

  • Philips screwdriver
  • A container for cleaning solvent (gas or dedicated filter cleaner)
  • Foam air filter oil
  • Grease
  • Clean rags
  • Protective gloves

Removing the Air Filter

  1. Remove the right-side number plate to access the airbox.
  2. Use a Philips screwdriver to loosen and remove the filter retainer screw.
  3. Carefully pull the filter and its cage out of the airbox. Avoid dropping dirt inside the intake.
  4. Inspect the air filter for tears, deformities, or excessive wear. If damaged, replace it.

Cleaning the Air Filter

  1. Pour cleaning solvent into a container and fully submerge the foam filter.
  2. Squeeze and massage the filter to remove dirt (do not twist or wring, to avoid tearing the foam).
  3. Repeat with fresh solvent as needed until all dirt is gone.
  4. Dry the filter completely before applying oil. Let it air dry in the sun for ideal results.

Oiling the Air Filter

  1. Evenly apply foam filter oil inside & out; massage to distribute thoroughly.
  2. Optional: Add a touch of grease to the filter sealing rim for a better seal against dust intrusion.

Reinstalling the Air Filter

  1. Reattach the filter cage inside the foam filter (line up mounting holes carefully for proper fitment).
  2. Place assembly into the airbox and install the retainer screw; do not over-tighten.
  3. Reinstall the number plate.

Replacement Tips

  • Always use a well-oiled filter—running dry or dirty risks engine damage.
  • Check the filter after every dusty ride.
  • If filter edges appear worn or filter fits loosely (common with melted airbox plastics), replace the filter – a fresh seal is critical.

Maintaining Peak Performance

Regular air filter cleaning adapts to how and where you ride; dusty tracks require frequent checks. Also inspect nearby plastics’ condition, unique to the DRZ125L’s exhaust routing—cracked or melted panels can let excess dirt in.

Trust MotoSport for genuine parts, fitment guidance, and ongoing expertise. Proper air filter care means riding longer, faster & safer.
