Shop parts for a 2024 Honda CRF450R-S Dirt Bike.
The 2024 Honda CRF450R-S is engineered for high performance in demanding off-road environments, making proper air filter maintenance crucial to engine health and longevity. Regular air filter cleaning and timely replacement will ensure optimal performance, prevent engine damage, and maintain peak airflow & filtration – especially important due to the model's high-revving SOHC engine and competitive nature.
Why Air Filter Care Matters on Your 2024 CRF450R-S
- High-performance engines like the CRF450R-S pull in large volumes of air, making the air filter a critical barrier against dust, dirt, and debris.
- Neglecting filter maintenance can result in contamination, poor power delivery, increased engine wear, and potentially catastrophic damage.
- The 2024 CRF450R-S uses a specially-shaped foam air filter designed for quick changes and easy access, so there's no excuse to skip this vital service.
Recommended Service Interval
- Check and clean the air filter after every ride in dusty conditions and at least every two to three rides in milder environments.
- Replace the air filter if it shows signs of excessive dirt, damage, or deteriorated foam.
Tools – Supplies Needed
- Genuine or high-quality aftermarket air filter (OEM part number 17213-... or see direct-fit options from MotoSport)
- Air filter cleaner or mild dish soap for washing
- Clean water
- Air filter oil (foam type)
- Nitrile gloves
- Plastic bag for oiling
- Lint-free towels
- New filter, if replacing
Cleaning Procedure: 2024 Honda CRF450R-S Air Filter
- Remove the Seat: Use the seat-release latch to access the airbox.
- Remove the Air Filter: Loosen the retaining hardware and carefully slide the air filter off the cage. Inspect for excessive dirt or physical damage.
- Wash the Filter:
- Place the filter in a bucket with air filter-specific cleaner or mild soap and warm water.
- Gently squeeze (do not wring or twist) to dislodge dirt – repeat as needed until clean.
- Rinse thoroughly with clean water and repeat if required.
- Dry Completely: Allow the filter to air-dry naturally. Do not use compressed air, direct heat, or sunlight.
- Oil the Filter:
- Once dry, pour appropriate air filter oil onto the filter, using a plastic bag to evenly distribute by massaging. The filter should be fully coated but not dripping.
- Inspect the Airbox – Seal Surfaces:
- Wipe the airbox and filter seal surface with a damp towel to remove residual dirt.
- Reinstall Filter: Slide the filter back onto the cage, ensuring a perfect seal with no gaps or twists.
- Install the Seat: Replace the seat carefully, making sure it seats securely and doesn't pinch the filter.
When to Replace the Air Filter
- If you notice torn foam, flaking, crumbling, or shrunken sealing flanges, replace the air filter immediately.
- It's smart to keep a spare filter on hand – this allows for quick swaps at the track or on extended rides.
Pro Tips for 2024 CRF450R-S Owners
- This model's air filter uses an easy-access mounting system, making changes fast with minimal tools.
- Always inspect the airbox seal and intake tract. Any dirt bypassing the filter can cause rapid engine wear.
- A properly oiled foam filter is slightly tacky to the touch but not saturated – too much oil can restrict airflow, too little allows dust through.
- Consider a filter cover or pre-filter for extended rides in extreme dust, especially in desert or sandy conditions.
Model-Specific Notes
- The 2024 Honda CRF450R-S shares filter dimensions with previous years (2021–2024), ensuring parts availability and easy fitment for spares.
- Owners have praised the updated airbox design for its user-friendly filter access, allowing riders to service their filter quickly between motos.
- Check your airbox breather and drain lines as part of every filter service for full air system protection.
