Why Air Filter Care Is Critical for Your 250XC

How to Access the Air Filter

- Locate the left side panel of your KTM 250XC–a simple latch releases the panel for toolless access.
- Remove the airbox cover to see the quick-release filter mounting system.
- Carefully detach the air filter by pressing the release tab and sliding it away from the intake–no tools required thanks to KTM's proprietary design–1–3.
Cleaning Your Air Filter
- Inspect the foam filter for excessive dirt or wear.
- Rinse the filter with a formulated filter cleaner or mild soapy water–never use gasoline or harsh solvents.
- Squeeze (do not wring) the filter gently to remove dirt and cleaner.
- Dry the filter thoroughly.
- Apply high-quality air filter oil to all surfaces. The filter should be sticky but not dripping.
- Reinstall by reversing the removal steps. Be sure the filter is seated evenly for a perfect seal.
Replacement Intervals
- Replace the air filter if it's torn, heavily stained, or no longer seals properly.
- MotoSport.com recommends checking after every ride in dusty conditions and cleaning or replacing as needed.
- For everyday use, weekly maintenance is generally sufficient.

Pro Tips for KTM Owners
- Inspect filter seating and seal every time you reassemble the airbox.
- Keep a spare filter on hand; swap quickly during back-to-back rides or races.
- Lubricate filter lightly–over-oiling can restrict airflow; under-oiling can let dust bypass the foam.
