Maintaining the air filter on your 2012 GAS GAS TXT-PRO-250 is critical for the bike's optimal performance, throttle response, and longevity. Trials bikes operate in dusty and demanding environments, so clean air is essential for the engine. Follow this MotoSport-exclusive guide to ensure peak performance and trouble-free riding.

How Often to Service the Air Filter

  • Clean the air filter after every race or ride–even more frequently in extremely dusty conditions.
  • Replace the air filter if you notice damage, tears, or if cleaning does not restore proper airflow.*

Tools & Supplies Needed

  • OEM-spec replacement air filter (if needed)
  • Air filter cleaner and oil
  • Rubber gloves
  • Clean rags
  • Phillips screwdriver

Step-by-Step Air Filter Removal

  1. Ensure the bike is cool and on a stable stand.
  2. Remove the seat and airbox cover:
    • Use the screwdriver to unscrew any fasteners securing the seat and then the airbox cover.
  3. Carefully remove the air filter:
    • Gently pull the air filter out of the airbox, taking care not to knock loose any dirt into the intake tract.

Cleaning the Air Filter

  1. Inspect for damage. If you see rips or cracks, replace the filter immediately.
  2. Pre-clean: Remove excess debris using air (from the inside out) or tap the filter gently.
  3. Wash: Use a specific foam filter cleaner–not gasoline or harsh solvents. Immerse in warm, soapy water, gently squeezing (never wring or twist). Rinse thoroughly.
  4. Dry: Allow the filter to air dry completely.
  5. Re-oil: Once dry, apply high-quality foam filter oil evenly. Massage the oil for thorough coverage but avoid over-oiling.

Reinstallation & Final Steps

  1. Clean the airbox with a damp rag while the filter is out.
  2. Ensure the sealing surface is clean and free of dust.
  3. Install the filter carefully, ensuring a tight seal all around the rim. An improperly seated filter may let debris enter the engine.
  4. Reinstall the airbox cover and seat securely.

Special Notes for 2012 GAS GAS TXT-PRO-250 Owners

  • This model's air filter is easy to access, but due to the compact nature of the trials airbox, take extra care to prevent dirt from falling inside during filter changes.*
  • Replace the air filter more frequently if the bike is ridden in deep water crossings or abnormal dust levels.
  • Inspect air filter mounting surfaces for warping or damage–any deformity can compromise the seal.
  • The TXT-PRO-250 air filter is shared with other models of similar years, but always confirm the exact part number when ordering replacements from MotoSport.

Pro Tips for Longevity

  • Consider buying multiple filters to always have a clean, oiled one ready to install.
  • Avoid over-oiling, which can restrict airflow and attract excess dirt.
  • After deep cleaning your bike, wait until the airbox is completely dry before installing a freshly prepared filter.
