Shop parts for a 2024 Yamaha YZ450F Dirt Bike.
The 2024 Yamaha YZ450F stands out for its innovative engineering and high-performance air intake system, ensuring optimal power and durability on the track and trail. Proper maintenance of the air filter is essential for engine longevity and consistent horsepower. Below you will find a MotoSport-exclusive guide for cleaning and replacing the air filter, specially tailored for your model.
Why Air Filter Maintenance Is Critical for the 2024 YZ450F
- Unique domed filter with high-volume airbox: Yamaha equips the 2024 YZ450F with a large, domed air filter and a new, high-flow airbox cover for superior airflow and throttle response.
- Model-specific sealing concerns: The stock filter uses a rubber strap for front sealing, but dirt can migrate under the cage, particularly at the front. Inspect this area carefully after every ride and apply filter grease liberally to ensure a proper seal–important for preventing engine damage.
- Aftermarket filter solutions: Aftermarket filters like Twin Air and Uni provide dual-stage filtration and improved sealing hardware to eliminate intrusion issues.
2024 YZ450F Air Filter Removal: Step-by-Step
- Remove the seat using the seat release latch under the rear fender.
- Wipe loose dirt from the airbox exterior before opening.
- Unclip the front rubber strap and carefully pull the air filter/cage assembly up and out of the airbox.
- Inspect for dirt under the filter cage–use a clean towel or shop vac to clear any debris that may have fallen into the intake tract.
- Separate the foam filter from the cage for cleaning or replacement.
How to Clean the Air Filter
- Pre-clean by gently tapping the filter to remove excess dirt.
- Wash the filter in a container of approved air filter cleaner or mild solvent. Gently squeeze (do not wring or twist) to avoid tearing the foam.
- Rinse thoroughly with clean water until all cleaning agents and debris are gone.
- Allow the filter to air-dry completely out of direct sunlight.
- Apply a quality foam air filter oil evenly. Massage the oil throughout the filter to ensure complete coverage.
- For the 2024 YZ450F: Heavily grease the sealing lip of the filter, especially at the front where Yamaha's stock cage is prone to leaks.
Reinstalling the Filter
- Reattach the filter to its cage, ensuring a snug fit and proper orientation.
- Place the assembly into the airbox, making sure the front of the filter sits firmly against the airbox flange.
- Secure the filter with the front rubber strap, checking that it is tight enough to prevent gaps for dirt entry.
- Wipe away any excess grease before reinstalling the seat.
When to Replace Your Air Filter
- When the filter is torn, excessively dirty, or the foam has begun to deteriorate.
- If you feel reduced performance on the track or see visible pollutants in the intake tract.
- With frequent cleaning, consider replacing after every 10-15 rides or races for optimal engine protection.
Proprietary MotoSport Notes for the 2024 YZ450F Owner
- The 2024 YZ450F air filter design offers increased airflow, but Yamaha's stock rubber strap may leave the front edge prone to leaks. Twin Air and other aftermarket kits fix this by using grommets and brackets for superior sealing.
- Always have a clean, pre-oiled spare filter ready for quick swaps between motos or during dusty conditions.
- Cleaning the throttle body area with a mini shop vac before starting the bike is recommended if any dirt is detected during filter changes.
- Compatible replacement filters: Yamaha OEM (BHR-14451-00-00), Twin Air, Uni, or Tusk–all designed specifically for the 2024 YZ450F.
Consistent maintenance of your 2024 Yamaha YZ450F air filter will keep your engine running strong and extend the life of your bike. Trust MotoSport for expert guides and all the parts you need to stay ahead on the track or trail.
