Below you will find MotoSport.com’s proprietary guide on air filter cleaning and replacement, along with essential tips every 2023 TTR125L owner should know.

Why Air Filter Maintenance Matters

Air filters protect your TTR125L's engine from dust, sand, and debris common to off-road environments. A neglected or dirty filter can cause poor performance and potentially catastrophic engine damage over time. The 2023 TTR125L uses a dual-layer foam air filter, providing optimal filtration and airflow to maintain the bike’s consistent power and throttle response†.

When to Clean or Replace Your Air Filter

  • Regular Use: Inspect the filter every 10-15 riding hours or after every few rides in dusty conditions.
  • Heavy Dust: Clean after every ride in sandy or exceptionally dirty environments.
  • Replacement: Replace your filter if you notice tears, excessively clogged foam, or signs of deterioration.

How to Remove the Air Filter

  1. Place the bike on a stable stand and remove the seat using the quick-release bolts.
  2. Open the airbox cover using a Phillips screwdriver.
  3. Loosen the filter wing nut or retaining pin and carefully remove the air filter to avoid dropping dirt into the intake.

How to Clean Your Air Filter

  1. Pre-clean by lightly tapping the filter to knock free loose debris and dirt.
  2. Place the filter in a container with a recommended foam filter cleaner or a mild detergent & warm water solution.
  3. Gently knead and squeeze (never wring or twist) until all oil and dirt are dissolved.
  4. Rinse thoroughly with clean water and repeat as necessary.
  5. Allow the filter to dry completely in a well-ventilated space, away from direct sunlight or heat sources.

How to Oil Your Clean Air Filter

  1. Once dry, apply high-quality foam air filter oil evenly to the filter's entire surface.
  2. Knead gently to work oil into the foam, ensuring all pores are saturated for maximum protection.
  3. Allow excess oil to drip away and check for complete, even saturation with no dry patches.

How to Reinstall the Air Filter

  1. Clean the airbox with a damp cloth. Prevent dirt from entering the intake while cleaning.
  2. Reinstall the filter, ensuring it sits flush and seals tightly against the airbox's mating surface.
  3. Secure with the wing nut or pin, replace the airbox cover, and reinstall the seat securely.

Model-Specific Tips for the 2023 Yamaha TTR125L

  • OEM dual-layer foam filter: The TTR125L uses a robust OEM-style dual-layer foam filter. Aftermarket options like Twin Air’s dual-stage filter are compatible and offer enhanced airflow and filtration†.
  • Pay attention to the sealing ring: The TTR125L's airbox requires the foam sealing ring to be flat and free of dirt–any gaps allow unfiltered air to the engine.
  • Use only foam filter oil: Do not substitute with standard engine oil; always use oils designed for foam filters.
  • Inspect intake tract gasket: The TTR's airbox seal should be periodically checked for cracking or dry rot, especially after power washing or water crossings.
