Air Filter Cleaning – Replacement Guide for 2017 Husqvarna FS450
The 2017 Husqvarna FS450 is a high-performance supermoto designed for the track and responsive to every form of maintenance—especially air filter care. A clean air filter is a direct line to consistent horsepower and long engine life. This MotoSport guide delivers a proprietary step-by-step method for cleaning and replacing the air filter specific to your FS450.
Why Air Filter Maintenance Matters on the FS450
The FS450 features a powerful 450cc engine with a high-flow intake system. This engine design makes regular air filter cleaning and replacement essential. Dust or dirt bypassing your filter can quickly wear engine parts, while an overly clogged filter chokes performance.
How Often Should You Clean or Replace the Air Filter?
- Clean after every ride in dusty or sandy environments.
- Replace the filter when it shows any signs of excessive staining, tears, or if the foam loses structure.
- Inspect more frequently if operating in extreme conditions or after rain rides.
Tools & Supplies Needed
- Quality air filter cleaning solution
- Fresh water source
- Filter-specific oil
- Latex or nitrile gloves
- Clean lint-free towels
- Replacement air filter for FS450 (optional)
How to Remove the Air Filter on a 2017 Husqvarna FS450
- Put the bike on a stand to keep it upright.
- Remove the seat using the quick-release latch under the rear fender.
- Carefully separate the side airbox cover—the FS450 uses a tool-less side panel system for fast access.
- Grasp the air filter cage tab and gently pull the filter straight out. Check for any sign of dirt getting past the seal—address immediately if found.
Cleaning the FS450 Air Filter (Reusable Foam)
- Gently tap the filter to remove loose dirt. Avoid banging it on hard surfaces.
- Apply air filter cleaner and let soak for several minutes to fully dissolve old oil and debris.
- Hand wash with warm water, squeezing (never wringing) the foam. Repeat until no dirt remains.
- Rinse thoroughly and gently squeeze out excess water. Allow the filter to air dry naturally—never use heat sources.
- Inspect the filter for tears or degraded foam structure. Replace immediately if any damage is found.
Oiling & Reinstalling the Filter
- Apply fresh, specific foam filter oil evenly. Work oil through the foam for complete coverage, squeezing until fully saturated but not dripping.
- Wipe excess oil from the rubber sealing edge for a tight fit in the airbox.
- Reinstall the air filter by aligning it with the cage tabs and firming into place for full seal contact all around.
- Reattach the side cover and seat, checking that panels fit flush without pinching the filter edge.
When & How to Replace Your FS450 Air Filter
Replace with a genuine or performance-grade aftermarket filter if you find:
- Foam tears, separations, or thinning
- Persistent discoloration or embedded contaminants
- Loss of structural integrity after cleaning
To replace, simply reverse the removal steps above using the new filter and ensure proper oiling as described.
Specific Tips for 2017 Husqvarna FS450 Owners
- The quick-access airbox on the FS450 makes filter servicing easier than most bikes—no tools required for airbox and seat removal.
- Seal check: FS450 filters must seat precisely on the cage to prevent sand and road debris from bypassing (common cause of engine scoring in supermoto use).
- Check for proper cage alignment; some owners report the filter cage tabs on the FS450 can be misaligned if rushed.
Regular care of your air filter is one of the simplest ways to maintain the legendary throttle response and race-day reliability your FS450 is designed for. If you need new filters, cleaning supplies, or accessories, MotoSport has everything for your 2017 Husqvarna FS450 to keep you riding strong.
