The RMZ450 comes equipped with a high-performance foam filter, specially designed for enhanced airflow and superior filtration.

What You Need to Know About the RMZ450 Air Filter System
- Dirt protection: The RMZ450 features ergonomically designed bodywork to shield the air filter from excess dirt and moisture.
- Foam construction: Most filters for this bike use dual-stage polyurethane foam–An outer layer catches larger debris, while a finer inner layer traps smaller particles.
- Simple service: The slim sub-frame and efficient design make filter access and replacement quick and easy.
Step-By-Step Guide – Cleaning the Air Filter
- Remove the seat: Use the seat release and gently lift the seat clear for access to the airbox.
- Filter removal: Unclip the filter cage and slide the foam filter out. Inspect for excessive dirt or damage.
- Initial cleaning: Gently tap the filter to remove loose dirt. Do not use pressurized air as it may damage the foam structure.
- Wash the filter: Soak the filter in a specialized foam filter cleaner or mild dish soap solution. Squeeze gently–avoid twisting or wringing, which can tear the foam.
- Rinse: Use clean water to fully remove soap and debris. Repeat until water runs clear.
- Dry completely: Let the filter air-dry completely before applying fresh filter oil.
- Oil application: Use a high-quality foam air filter oil. Massage the oil evenly into the entire filter, including corners and seams.
- Reinstall: Replace the filter into the cage, ensuring a secure seal at all contact points. Re-clip and reinstall the seat.
When to Replace Your Air Filter
- Replace if you notice tearing, crumbling, or loss of foam integrity–especially after repeated cleanings.
- For aggressive riding or extremely dusty conditions, inspect and clean after every major ride.
- For casual use, plan for a filter replacement every 20–30 operating hours, or as dictated by the manufacturer's service intervals.
Proprietary MotoSport Tips for Your RMZ450
