This guideprepared exclusively for MotoSport customerscovers the unique air filter features of this model and shows you proprietary cleaning & replacement steps to maximize engine protection and durability.
Model-Specific Air Filter Notes
- Dual-layer foam design: The 300SE-R air filter utilizes two bonded open-pore foam layers for maximum filtration and optimal airflow. The outer coarse foam blocks larger debris, while the inner fine foam traps minute particles for superior engine safety.
- Increased air volume: The filter design improves airflow into the intake, supporting robust engine power and efficient fuel delivery.
- OEM fitment: Only filters specific to Sherco SE-R 300 models (2014–2024) ensure proper sealing – avoid generic parts for all 2018 Sherco 300SE-R maintenance.
Proprietary MotoSport Air Filter Cleaning Procedure
- Removal: Unlock seat and airbox cover. Carefully detach the air filter, noting the position – avoid letting dirt fall into the intake.
- Pre-clean: Tap or gently brush off loose debris without compressing the foam.
- Washing: Submerge the filter in a bucket of approved foam air filter cleaner. Gently squeeze (do not twist) until oil and contaminants release. Repeat with clean water.
- Drying: Allow the filter to air dry thoroughlynever use compressed air or high heat sources.
- Inspection: Check for damaged or degraded foam, compromised seams, or tears. Replace if any defects appear; always install a fresh filter before competitive riding or after major service intervals.
- Oiling: Apply professional-grade air filter oil, massaging it evenly through both foam layers. Do not oversaturate; squeeze out excess gently.
- Reinstallation: Ensure the filter is seated flat and fully seals against the airbox. Confirm proper placement of the cage and securing bolt.
Replacement Intervals – Inspection Tips
- Inspect after every ride in dusty or sandy conditions to prevent clogging and engine wear.
- Replace immediately if foam is deteriorating, seams separate, or persistent breakdown of filtering ability is observed.
- For maximum engine life, keep an extra clean, oiled filter on hand during multi-day events or when riding in varied terrain.
Special 2018 Sherco 300SE-R Considerations
- Factory sealing ring: Unique wide, flat sealing surface ensures full contact with the airbox, reducing unfiltered air bypass. Always check for even sealing during installation.
- Filter compatibility: Only use filters marked for 2018 Sherco 300SE-R – twin-air and no-toil models for Sherco are verified options.
- Aftermarket upgrades: High-flow filters require diligent cleaning. If upgrading, adjust maintenance intervals based on your riding conditions.
