Shop parts for a 2024 Sherco 300SEFAC Dirt Bike.
Keeping the air filter on your 2024 Sherco 300SEFAC clean and properly serviced is the single most important routine maintenance to preserve engine life and performance. Sherco equips the 300SEFAC with a dual-stage foam filter, expertly engineered for maximum protection and optimal airflow—especially crucial for enduro riders who push through dust, water crossings, and heavy roost.
Why the 300SEFAC Air Filter Matters
- Factory dual-stage design: The OEM foam air filter uses a coarse outer shell laminated to a fine inner core, which maximizes filtration while maintaining strong airflow for engine responsiveness and power.–
- Broad intake volume: Twin Air filters increase air volume around the filter, providing more efficient airflow and reduced clogging.
- Resilient glue seams: Proprietary adhesive and a greaseless sealing ring ensure the filter stays securely sealed in your airbox without breakdown under repeated cleaning cycles.–
Note: Sherco designed the 300SEFAC with premium seals and high-flow intake specifically for the demands of extreme enduro. Owners should clean more frequently in dusty or wet conditions, and always install the filter with the correct orientation and oil coverage.
Air Filter Cleaning Procedure
- Remove seat and access the airbox. Release the quick-connect filter retainer (Sherco's no-tool system makes this step simple).
- Carefully detach the dirty filter, avoiding dropping any debris into the intake tract.
- Shake off loose dirt. Rinse the foam filter gently in a tub of warm water and approved foam filter cleaner. Avoid gasoline, which damages foam and adhesives.
- Rinse thoroughly until clean. Squeeze out excess liquid—do not twist or wring harshly.
- Allow to air dry completely, away from direct heat or sunlight.
- Saturate with high-quality foam filter oil, ensuring full coverage but not excess residue. Massage oil throughout both layers.
- Inspect sealing ring and foam edges for tears or breakdown. Replace if damaged.
- Reinstall into the airbox, ensuring the seal contacts evenly and no gaps exist. Secure with the retainer.
Air Filter Replacement Recommendations
- Replace every 15–20 hours in normal use, or immediately if the filter is damaged, loses its seal, or cannot be fully cleaned.
- Stock up on spare filters if riding events, races, or multi-day trips are planned, as clean filters are critical for each ride.
- Twin Air and other OEM-spec filters are proven for the 2024 SE Factory platform—confirm fitment and style before purchase.
Specific Notes for 2024 Sherco 300SEFAC Owners
- Factory airbox can be quickly accessed using Sherco's 1/4-turn retention system for faster filter swaps during races.
- O-ring seals and fitment are tuned for waterproofing, but always check for debris or water before reinstalling after wet rides.
- Protect your intake funnel and throttle body during cleaning—cover with a clean rag or intake plug.
- Do not skip regular filter checks: The 300SEFAC's high-performance two-stroke engine is more sensitive to air restriction and dirt ingress than most.
