Why Air Filter Service Matters for the 2019 Sherco 450SEFFAC

  • Dual-stage, flame-laminated foam filters on the 450SEF are engineered to stop even ultra-fine dust and debris while providing full airflow needed for robust performance.
  • This model’s engine runs best when the filter is clean and properly sealed. Neglect leads quickly to throttle lag or premature engine wear.
  • Sherco’s airbox design provides easy access, but a tight seal around the filter rim is vital to prevent bypass of particulate matter.

How Often Should You Service the Filter?

  • Clean after every dusty ride or raceespecially if riding in dry, silty, or muddy conditions.
  • Inspect regularly: Even if not replacing, always inspect before each ride for any holes, tears, or loose fit.

Cleaning & Oiling Procedure

  1. Remove the seat to access the airbox. Gently unclip the air filter cage from the airbox.
  2. Seal the intake with a clean rag to prevent debris entry.
  3. Check for any signs of degradationreplace if there are tears, detachment, or crumbling seams.
  4. For approved foam filters:
    • Clean the filter using a foam filter cleaner or mild detergentdo not use gasoline, which breaks down foam and glue integrity.
    • Rinse thoroughly with warm water, squeezing lightly (don’t wring).
    • Allow the filter to dry completely before oiling.
    • Apply high-quality foam filter oil evenly, working it through the foam. The filter should be thoroughly colored but not dripping.
    • Use a filter rim grease or the manufacturer’s sealant on the mating edge for added protection from fine dust bypass.
  5. Reattach the filter securely onto the airbox cage, ensuring complete and even contact around the rim.
  6. Reinstall the seat. Start the bike and listen for proper idle and throttle response.

When to Replace the Air Filter
