Shop parts for a 2025 Sherco 250SEFACTORY Dirt Bike.
The 2025 Sherco 250SEFACTORY comes equipped with a new airbox and air filter access system designed for quick, tool-free maintenance. As an owner, this means filter cleaning – or swapping in fresh foam – is faster, cleaner, and more reliable in harsh off-road conditions.
Key Features – 2025 Sherco 250SEFACTORY Air Filter System
- Quick-access side panel: The air filter is reached by removing the side panel, which is designed to come off easily with a single hand and is held in place by a quick-release folded-over clip.
- Dual-stage foam construction: The OEM (and most aftermarket) air filters use dual-bonded foam, offering enhanced dust and debris filtration while maintaining optimal airflow for the two-stroke engine.
- Integrated drainage: The airbox features a drain hole and internal flap, efficiently preventing water accumulation even under severe riding conditions. However, monitor the drain for mud buildup.
- Protected electronics: The battery and relays have been repositioned inside the airbox area for improved wire routing and protection, but are still accessible.
Cleaning – Replacement Instructions
- Remove the side panel: Press the quick-release clip, then gently pull off the side panel for instant access.
- Release and remove the filter: Unclip the air filter holder. Carefully pull out the foam filter to avoid dirt dropping into the intake.
- Inspect the filter: If the filter is excessively soiled, damaged, or cannot be cleaned effectively, replace it with a new dual-stage foam filter designed for 2025 Sherco SE Factory models.

For cleaning:
- Gently tap the filter to remove loose dirt.
- Wash thoroughly with a dedicated foam filter cleaner or mild soap & warm water. Squeeze, do not wring or twist.
- Rinse thoroughly – repeat if necessary until water runs clear. Allow the filter to dry completely.
- Apply high-quality foam air filter oil evenly, massaging it into the foam for complete coverage.
- Let any excess oil drain, then reinstall the filter.
- Check the airbox and drain: Wipe clean any dust or debris. Inspect the drain hole – remove packed mud if present to prevent water buildup.
- Install the cleaned or new filter: Replace the filter securely, ensuring proper alignment and seal. Reattach the holding clip and reinstall the side panel.
Unique Tips for 2025 Sherco 250SEFACTORY Owners
- Mud awareness: The new airbox design works well in wet conditions, but if you frequently ride in deep mud, check the drain hole after each wash or ride. Clogged drains can lead to water buildup.
- Quick changes: Practice removing and installing the side panel at home. In a race or when out on the trail, this design allows virtually one-handed filter swaps for rapid service.
- Use the right filter oil: Dual-stage foam filters on the 250SEFACTORY require oil formulated for off-road foam filters–avoid older spray-type or engine oils.
- OEM and aftermarket fit: Most 2025 Sherco SE Factory (125/250/300) compatible filters are interchangeable, but always check filter fit and sealing before riding.
Stay proactive with filter maintenance to keep your 2025 Sherco 250SEFACTORY running strong, ensuring both long engine life and peak performance every ride.
