Shop parts for a 2019 Sherco 125SE-R Dirt Bike.
Keeping your 2019 Sherco 125SE-R running at peak performance depends on regular air filter maintenance. The 125SE-R uses a dual-stage foam air filter, designed for optimal engine protection and airflow. With a two-layer, open-pore foam construction, this filter system excels in off-road conditions–keeping abrasive debris out of your engine while maintaining high airflow for top power output.
Why Clean & Replace Your Air Filter?
- Maximum Filtration: Dual-layer foam captures both coarse dirt and fine dust, protecting engine internals.
- Consistent Airflow: Clean filters mean more air reaches your intake, maximizing throttle response and engine efficiency.
- Model-Specific Design: The filter is fused together, preventing dirt from getting trapped between layers, tailored for Sherco's airbox and sealing surface.
Recommended Cleaning Interval
- Clean after every ride in dusty or sandy conditions.
- For regular trail riding, clean every 2–3 rides.
- Replace the filter if damage, permanent stains, or excessive wear are present.
Cleaning Steps for Sherco 125SE-R Air Filter
- Remove the seat and airbox cover.
- Gently remove the air filter, avoiding dirt fallout into the intake.
- Inspect for tears, breakdown, or glue seam separation. Replace if needed.
- Rinse the filter in filter-safe cleaner or mild detergent, not gasoline.
- Squeeze (do not wring) the filter to remove cleaning solution.
- Rinse with clean water and repeat until all residue is gone.
- Allow to air dry completely.
- Once dry, apply foam filter oil evenly to both inner and outer layers.
- Work oil into the foam–the entire filter should be tacky, not dripping.
- Clean the airbox and sealing surface before reinstallation.
- Ensure the filter seats flat and seals snugly.
Replacement Guide
- For the 2019 Sherco 125SE-R, the Twin Air and UNI Filter are popular options. Both feature dual-layer, washable foam designed specifically for your model.
- Check part numbers for an exact fit: Twin Air #156016 or UNI NU-3808ST.
- Always install with the sealing ring flush against the airbox surface–improper fit can let unfiltered air bypass.
Tips Unique to the 2019 Sherco 125SE-R Owner
- The Sherco foam filter's fused layers and custom-sealing ring ensure maximum airbox contact–never substitute with a generic filter.
- Keep spare filters and sealing grease on hand for quicker swaps during multi-day rides.
- Inspect the air filter cage and airbox for warping or cracks–these can compromise filter performance even with a new filter.
Important Notes
- MotoSport recommends checking the OEM maintenance schedule for any updates specific to your riding environment.
- Always use a filter oil designed for foam filters–other oils may not provide proper adhesion or filtration.
- Careless handling can result in torn foam or misaligned sealing surfaces. Take your time to ensure your Sherco's engine stays protected.
