The 2010 Husaberg FE390 features a unique high-mounted air filter setup, located just under the seat and forward near the gas cap. This central and elevated location helps protect the filter from dust, mud, and water–making it ideal for aggressive trail riding or race conditions. The FE390's design also includes a quick-release seat latch, streamlining access for maintenance and minimizing hassle when cleaning or replacing the air filter–these details make a notable difference from comparable models in the Husaberg lineup .

Why Clean and Replace Regularly?

  • Performance: A clean air filter ensures the engine receives optimal airflow, preserving horsepower and throttle response.
  • Engine Protection: Dirty filters allow dust and micro-debris to enter, shortening engine life and risking expensive repairs.
  • Fuel Efficiency: Clean intake air maximizes fuel burning efficiency–a blocked filter leads to poor fuel economy.

Recommended Replacement Air Filters

  • HiFloFiltro Air Filter, compatible with Husaberg FE390 2009–2012 models
  • ProX Racing Parts Air Filter (2009–2012 FE390)
  • Hiflo Air Filter HFF6013 (covers FE390, FE450, FX450, FE570, FS570)

Cleaning & Replacement Procedure

  1. Seat Removal: Use the quick-release latch to lift off the seat. The air filter sits centrally up front beneath the fuel cap.
  2. Filter Inspection: Remove the air filter carefully. Inspect for dust, dirt, and physical damage.
  3. Cleaning (Foam Filters):
    • Gently tap or brush off loose debris.
    • Soak the filter in a dedicated air filter cleaner or mild degreaser. Do not use gasoline or overly harsh chemicals–this can damage the foam and reduce filtration performance.
    • Rinse thoroughly with warm water. Squeeze out excess water (do not wring–this tears the foam).
    • Dry naturally–avoid high heat.
    • Re-oil the foam filter with air filter oil, ensuring an even coat but without heavy saturation. Squeeze out excess oil.
  4. Replacement: For damaged, deteriorated, or excessively clogged filters, fit a fresh replacement matching OEM specs (see recommended filters above).
  5. Reinstallation: Place the cleaned or new filter securely back in the airbox. Ensure the sealing surface is properly mated to prevent air leaks.
  6. Seat Replacement: Reattach the seat, confirming it locks firmly in position.

Special Maintenance Notes for the 2010 FE390

  • The distinctive high location reduces contamination in most conditions, but frequent cleaning is still essential if riding in extremely dusty or muddy terrain.
  • The air box is easily accessible compared to other "70-degree" Husaberg engines–the seat rarely fights you on refitting, thanks to the quick-release design.
  • Use only recommended filter oils–some aftermarket fluids may degrade the foam or not capture micron-sized particles efficiently.
  • Routine inspection (every ride if conditions are harsh, or every 3 rides for moderate use) preserves engine longevity and peak performance.

For any FE390 owner, maintaining a clean and properly installed air filter is essential to the durability and performance of the bike—trust MotoSport for all your filter, seal, and accessory needs specific to the 2010 Husaberg FE390.
