Step-by-Step Air Filter Removal
- Ensure the bike is cool and parked on a level surface in a clean environment.
- Open the airbox cover using the toolless latch.
- Carefully withdraw the air filter and attached cage, taking care not to knock debris into the intake tract.
- Inspect the filter box. Remove any loose dust or debris with a clean cloth.
Cleaning Your Air Filter
- Separating the foam from the cage, gently wash the filter with an approved filter cleaner or mild dish soap. Do not use gasoline as it can degrade filter glue and foam structure.
- Rinse thoroughly with clean water. Squeeze – never wring – the filter to avoid tearing the foam.
- Let the filter air dry completely before re-oiling.
- Apply a high-quality foam filter oil evenly. Work the oil through all filter surfaces for maximum dust-trapping performance.
Inspection Before Reinstallation
- Examine for any tears, separated seams, or rigid glue. Replace the filter if there is any damage.
- Check the filter cage and airbox seal surfaces for cleanliness and wear.
Reinstalling the Air Filter

- Insert the cage and filter into the airbox. The 2025 KTM's intuitive mounting design makes alignment straightforward.[1]
- Secure the filter with the standard latch or clip.
- Replace and secure the airbox cover.
Replacement Interval – Pro Tips
- Inspect the air filter after every ride in dusty or wet conditions. Even in mild environments, inspect every 3-5 hours of riding.
- Replace the filter if: signs of undue wear, persistent dirt, glue breakdown, or foam damage appear.
- Always keep a backup pre-oiled filter ready for quick swaps.
- In very wet or muddy events, consider using a water-resistant air filter cover for extra engine protection.[3]
