Shop parts for a 2018 Husqvarna 701Supermoto Dirt Bike.

The 2018 Husqvarna 701Supermoto is renowned for its agility, robust power delivery, and exceptional on-road and off-road performance. Proper air filter maintenance is critical to maximize engine life, maintain horsepower, and uphold the legendary fuel efficiency and performance expected from this model. This guide by MotoSport.com details proprietary steps for cleaning and replacing your air filter, tailored to the unique setup of the 701Supermoto.

Understanding Your Air Filter: Types and Features

  • OEM Paper Filter – Standard from the factory, designed for essential filtration and reasonable airflow.
  • Upgraded Filters – Aftermarket options, such as oiled cotton (DNA, Twin Air, NiceCNC High Flow), can improve airflow up to 50% and provide 98-99% filtration efficiency, helping boost power while ensuring engine safety.
  • Reusable air filters, especially high flow models, require periodic cleaning and re-oiling – typically every 5,000 kilometers for optimal results.

Step-by-Step: Cleaning – Replacement Instructions

  1. Access the Air Filter
    Remove the seat by releasing the latch. The seat should come free easily. If tight, carefully use a plastic trim tool.
    Next, detach the panel around the ignition key switch, which is held by two pegs. Use care to prevent damage or scratches.
  2. Remove the Filter
    The filter is housed inside the airbox, covered by a lid and typically secured with two screws. Remove the lid to expose the filter. OEM filters will be a paper element; performance filters may be foam or oiled cotton.
  3. Clean (Reusable Filters Only)
    For oiled cotton or foam filters:
    • Tap off loose dirt gently.
    • Wash with approved filter cleaner and warm water. Do not use gasoline or harsh chemicals.
    • Rinse thoroughly and allow to air dry – avoid heat sources.
    • Re-oil filter evenly with air filter oil, ensuring coverage but not oversaturation.
    Note: If using aftermarket kits, such as DNA Stage 2, follow specific manufacturer instructions for element and lid fitting.
  4. Replace (When Needed)
    For non-reusable paper filters: Discard and replace with a new OEM or recommended aftermarket filter.
    High-flow reusable filters should only be replaced if damaged or if performance drops after repeated cleaning.
  5. Reinstall the Filter and Lid
    Seat the clean or new filter securely in the airbox with the lid installed and screws tightened. Apply a light silicone lube to the studs if needed for smoother fitment.
  6. Reassemble Panels and Seat
    Replace the key switch panel, ensuring it clicks into the pegs. Reinstall the seat.

Critical Notes for 701Supermoto Owners

  • The intake snorkel in the airbox is notably restrictive; upgrading to a performance filter kit frees up airflow and increases responsiveness.
  • Periodic cleaning every 5,000 km is vital. Ignoring maintenance can lead to reduced horsepower, sluggish throttle response, and engine wear.
  • For aggressive riding or dusty conditions, inspect and clean the filter more frequently.
  • Improved filters contribute up to 4% horsepower gain and fuel savings, though daily riders may not always notice incremental changes.

Proprietary MotoSport Tips for Peak Performance

  • Always check for a proper seal around the filter in the airbox to prevent unfiltered air intake.
  • Ensure the filter is fully dry before oiling to avoid moisture ingress.
  • Use only MotoSport-approved cleaning agents and filter oils for best engine compatibility.
  • Consider a Stage 2 intake kit upgrade if seeking maximum airflow – but always pair with appropriate tuning.

Routine air filter maintenance not only safeguards the legendary Husqvarna engine but also assures you experience every ounce of performance this supermoto was built to deliver. Trust MotoSport.com for expert parts, tools, and advice specific to your 2018 Husqvarna 701Supermoto.
