Regular cleaning & replacement of the air filter ensures peak performance, superior airflow, and maximum engine protection. Follow this MotoSport-exclusive guide to care for your 500EXCF's air filter.

Why Air Filter Care Matters for Your 500EXCF

  • High-performance engine: The 500EXCF's potent engine requires consistent, clean airflow for optimal operation.
  • Extra-large Twin Air filter: This model comes stock with a durable, oversized Twin Air filter for extended protection in rugged conditions.
  • Innovative housing design: The rigid filter cage and housing are crafted for easy removal, even in muddy scenarios—no tools needed at any stage.

How to Remove & Inspect the Air Filter

  • Ensure the bike is off and cool before starting.
  • Remove the seat by unlatching the seat release at the rear of the saddle.
  • Access the airbox directly beneath the seat. The electrical components are placed above to avoid interference, making filter handling even simpler.
  • Unclip the air filter cover and carefully lift out the filter and its cage.
  • Inspect the filter for dirt, debris, tears, or signs of oil saturation.

Cleaning Instructions for the Twin Air Filter

  • Gently remove the filter from the cage.
  • Wash the filter with a dedicated foam filter cleaner or a mild, bike-safe degreaser. Avoid gasoline or solvents as they can damage foam elements.
  • Rinse with warm water, squeezing (not wringing) to preserve foam integrity.
  • Allow the filter to completely dry in a dust-free environment.
  • Re-oil the filter with air filter-specific oil, ensuring even application but avoiding over-saturation.

When to Replace the Air Filter

  • Replace if the filter has tears, the foam is hardening, or cleaning does not restore function.
  • KTM recommends frequent inspection; more often if you ride in especially dusty or wet environments.
  • Direct-fit replacements are available – look for Twin Air or OEM matches to maintain original performance.

Reinstalling the Air Filter on Your 2019 KTM 500EXCF

  • Mount the dry, oiled filter back onto the rigid cage, aligning notches and ensuring a perfect seal around the airbox.
  • Clip the air filter cover back in place.
  • Double-check the seal; any gap can let dirt bypass the filter.
  • Reinstall your seat and verify all components are secure before riding.

2019 KTM 500EXCF Model Notes

  • Thanks to the design of the air filter system, you can remove or swap filters in seconds, even if your gloves or hands are full of dirt.
  • Keep the area around the airbox and seat latch clean; electrical wiring is routed above the air filter for convenience and protection.
  • The zero-dirt footrest and raised selector lever help keep mud away from crucial moving parts, reducing the grit that can reach your intake area.

Regular air filter maintenance protects your 2019 KTM 500EXCF's engine, extends component life, and keeps you in the lead. Trust MotoSport to supply the parts and upgrades you need to keep performing at your peak.
