Strict maintenance is especially important for this model, as its high-performance two-stroke engine relies on consistent airflow for optimal power delivery.

Why Air Filter Care Matters

  • Performance: A clean air filter ensures best throttle response and maintains the Sherco's characteristic strong low-end torque and clean top-end.
  • Longevity: Regular cleaning or timely replacement prevents engine wear, which is key for the 300SE-R's longevity, especially in off-road or dusty environments.

Cleaning the Air Filter

  1. Remove the seat using the quick-release lever and access the airboxthis is particularly straightforward on the 300SE-R thanks to Sherco's tool-less seat removal.

  3. Separate the foam filter from its cage.
  4. Gently tap the filter to remove loose dirt, then wash it in a dedicated foam filter cleaner or a gentle degreaser. Do not use gasolineit degrades foam and adhesives.
  5. Rinse thoroughly with warm water and squeeze out (never twist) excess liquid.
  6. Allow the filter to air dry completely.
  7. Once dry, apply air filter oil evenly, working it through the foam. MotoSport recommends high-tack foam filter oils for off-road riding to catch fine particles.
  8. Inspect the filter for rips or weak seams. Replace if any damage is found or if glue seams show signs of breaking down.
  9. Reinstall the filter on the cage and mount into the airbox, ensuring a tight seal to the airbox rim. The Sherco uses a thick, flat foam sealing ring to maximize dust exclusion.

Replacement Frequency – Special Note

  • Check after every ride if riding in very dusty or muddy conditions, or every 2-3 rides in moderate environments.
  • Always consider replacement at the end of each season, or sooner if the filter loses its structure or sealing ability.
