Why Clean & Replace the MC85 Air Filter?

Regular air filter maintenance keeps your engine running strong and maximizes the innovative updates on the 2025 MC85, including the revised cylinder head, ignition system, and precision jetting. The bike's high-flow, top-side air ducts and new filter mounting system can only work optimally when the filter is clean and debris-free.

Tools & Supplies Needed

  • Nitrile gloves
  • Clean rags
  • Air filter-specific cleaning solvent
  • Specialty air filter oil
  • Replacement Twin Air filter (optional, recommended)
  • Contact cleaner (optional)

Step-by-Step MC85 Air Filter Removal

  1. Prep: Place the bike on a stable stand. Wash the exterior if muddy to avoid contaminants entering the airbox.
  2. Remove Side Panel: Thanks to the fail-proof mounting design, simply pop off the side panel by hand–no tools required.
  3. Extract Filter: Gently disengage the air filter from its secure mount. Take care not to knock dirt into the air boot.

Cleaning the Air Filter

  1. Pre-Clean: Tap the filter gently to remove loose dirt. Avoid heavy squeezing or wringing.
  2. Solvent Bath: Submerge the filter in a non-petroleum filter-specific cleaner. Agitate gently until clean.
  3. Rinse: Rinse thoroughly with clean water, avoiding hot water which can damage filter materials.
  4. Dry: Air dry fully. Do not use compressed air or heat sources as they may compromise filter structure.

Oiling & Preparing the Filter

  1. Apply air filter oil evenly, working it carefully into the foam. Coverage is critical for dust trapping efficacy.
  2. Remove excess oil to prevent dripping into the airbox but ensure total coverage–the 2025 MC85's high-flow airbox design relies on a properly oiled filter.

Reinstalling or Replacing the Filter

  1. Inspect the airbox for residual dirt, wiping clean as necessary.
  2. Ensure the filter is mounted securely to prevent unfiltered air intake. The new design ensures a tight, ergonomic fit–listen for the audible click to confirm it's locked in place.
  3. Re-attach the side panel firmly by hand.

When to Replace the MC85 Air Filter

  • Replace after heavy contamination, visible tears, or loss of foam structure.
  • If you ride in extremely dusty environments, keep a fresh filter on hand for quick swaps between motos.

Model-Specific Tips for 2025 GAS GAS MC85 Owners

  • The new air duct system improves performance, so diligent filter care prevents airflow restrictions and protects the new, lighter engine from premature wear.
  • The fail-proof mounting design means there's no excuse for an improperly installed filter–always double-check seating after cleaning or replacement for full protection and performance.
  • Pay attention to the lightweight frame and textured side panels: Use a clean rag to wipe down mounting points before closing the panel to maintain a tight seal and ensure lasting ergonomics for the rider.
