Key Features — 2026 WR450F Air Filter Design
- Dual-stage foam construction: Coarse outer foam traps larger debris, while fine inner foam captures smaller particles for maximum engine protection.
- Tool-free access: The air cleaner cover is designed for easy removal – no tools needed, reducing service time.
- Washable & reusable: The filter can be cleaned and reused, lowering maintenance costs and reducing waste.
- Optimized airflow: Improved volume and airflow for the WR450F's high-revving 450cc four-stroke engine, supporting broad power delivery across the RPM range.
- Flat foam sealing ring: Ensures a secure fit, preventing dirt ingress from the airbox perimeter.
Air Filter Cleaning Steps - MotoSport Exclusive Method
- Turn off engine, ensure bike is cool and positioned securely on a stand.
- Remove side panels to access the air cleaner cover. Lift off cover using tab – no tools needed.
- Carefully extract the air filter. Note the sealing orientation; the flat foam ring faces the airbox perimeter.
- Inspect filter and airbox for dirt or debris. Clean airbox with a damp cloth if necessary.
- In a clean container, apply MotoSport-approved foam filter cleaner solution. Gently knead the filter – avoid twisting or wringing, which may damage seams.
- Rinse thoroughly with water. Repeat until all contaminants and old oil are removed.
- Allow filter to air dry completely – do not use compressed air or heat.
- Re-oil both foam layers evenly with a premium filter oil. Ensure oil penetrates without oversaturating to prevent airflow blockage.

- Reinstall air filter and cover securely. Confirm no gaps around the perimeter.
