This makes air filter maintenance easy for racers and enthusiasts who want to maximize performance while minimizing downtime.

Before You Begin: Key Details for EX250F Owners

  • The 2024 EX250F uses a Twin Air dual-stage foam air filter designed for maximum airflow and superior filtration. This filter construction provides increased protection in challenging conditions and is critical to the bike's performance and durability–the airbox ensures a clean, direct intake to maximize horsepower.
  • The innovative airbox design allows for quick, tool-free filter changes thanks to a precise mounting system and accessible layout. The minimal tools required streamline course-side and garage maintenance.
  • Do not use gasoline or petroleum-based products to clean the air filter foam–these substances can damage the foam structure.

Step-by-Step Air Filter Removal

  1. Turn off the engine and ensure the bike is cool and in a stable position.
  2. Remove the seat by releasing the fasteners under the rear and lifting the seat off.
  3. On the right side, remove the side panel to access the airbox if additional space is needed.
  4. Unlock and remove the air filter box cover. Put the cover aside in a clean area to avoid contamination.
  5. Carefully pull the air filter from its quick-release mounting in the airbox, avoiding contact with dirt or debris on the airbox rim.

Air Filter Cleaning Procedure

  1. Tap the filter gently to remove loose dust and debris.
  2. Wash the filter with a high-quality, foam-specific air filter cleaner in a bucket of warm water. Avoid twisting or wringing the foam, as this can cause tearing.
  3. Rinse thoroughly with clean water until no dirt or soap remains. Allow to air dry completely–never use heat sources or direct sunlight as this may damage the foam glue.
  4. Once dry, apply air filter oil evenly, ensuring the filter is well-saturated but not dripping. Massage the oil gently throughout the foam for optimal, consistent protection.
  5. Inspect the filter for any damage. Replace if there are tears, hard spots, or excessive wear.

Air Filter Reinstallation

  1. Clean the airbox with a damp cloth and inspect for dust or debris. Be careful not to push dirt into the intake tract.
  2. Install the freshly oiled filter into the mounting system, ensuring a perfect seal around the airbox. The sealing ring must be flush for the best engine protection and performance.
  3. Reattach the air filter box cover securely.
  4. Reinstall the side panel if removed, and replace the seat, ensuring all fasteners are tight and secure.

Replacement Timing & Special Notes

  • Clean the air filter after every ride in dusty or muddy environments. In cleaner conditions, inspect after every ride and clean or replace as needed.
  • Always use OEM-quality replacement filters such as the proprietary Twin Air units specified for the 2024 EX250F to preserve airflow and engine integrity.
  • Never run the engine without the air filter, even briefly–dirt intrusion can cause rapid engine damage.
  • The EX250F's improved airbox design and factory-grade pre-oiled filter options allow you to keep a spare handy for even faster swaps on race day.
