If you ride a 2019 Husqvarna 701 Supermoto, your air filter is essential for optimal engine performance and longevity. Keeping it clean and in top shape ensures your powerhouse 701 single-cylinder breathes freely, delivering the throttle response and torque that sets this model apart. Here is MotoSport.com's proprietary guide dedicated to your exact make, model, and year–offering tried-and-true methods specifically tailored to the 701 Supermoto platform.

Unique Features of the 701 Supermoto Air Filter

  • Filter Style: The 2019 701 Supermoto uses a high-quality paper air filter element, easily accessible under the seat and designed for straightforward removal and replacement.
  • Performance Note: The stock 701 filter provides an excellent balance of airflow and filtration. High-flow reusable cotton filters are also compatible for riders desiring increased horsepower, but require regular re-oiling.
  • Engine Sensitivity: The 701's advanced fuel injection and powerful 692.7cc motor make it especially sensitive to air restriction. A clean filter is absolutely critical to avoid performance loss and engine damage.

When to Clean or Replace the Air Filter

  • Cleaning Interval: Husqvarna owners should inspect the filter every 500-1000 miles (800-1600 km), or more often in dusty riding conditions. For reusable filters, cleaning every 5000 km (3100 miles) is recommended for optimal flow.
  • Replacement Interval: Replace a paper filter when it shows signs of excessive dirt, damage, or moisture that cannot be removed by gentle cleaning. Always replace if you notice decreased performance or unusually high fuel consumption.

How to Locate, Remove, and Replace the Air Filter

  1. Access the Airbox: Remove the seat using the rear release latch. Locate the filter box under the seat assembly for the 701 Supermoto.
  2. Remove Filter Cover: Unscrew the filter box top part. Keep track of any screws or collars for reinstallation.
  3. Extract Air Filter: Lift the filter element straight up, avoiding contact with the dirty side to prevent debris from falling into the intake.
  4. Inspect and Clean: For paper filters, gently tap the filter to release loose dust. Do not use water or compressed air, as it may damage the filter medium. For reusable cotton/oil filters, follow the filter-specific cleaning and re-oiling instructions.
  5. Replacement: If the filter is damaged or heavily soiled, install a new OEM or high-flow unit compatible with the 2019 model.
  6. Reinstall: Place the new or cleaned filter in the correct orientation. Reattach the airbox cover securely and reinstall the seat.

Strategy for Reusable High-Flow Filters

  • Cleaning: Wash with gentle detergent and water, rinse thoroughly, and let air-dry completely.
  • Oiling: Apply filter-specific oil evenly to restore filtration properties, ensuring no area is left dry. Over-oiling can hinder airflow, so use sparingly.
  • Benefit: Properly maintained high-flow filters can enhance throttle response, fuel efficiency, and even increase horsepower by up to 4%–perfect for the 701 Supermoto's performance-minded owner.

MotoSport Pro Tips Specific to the 701 Supermoto

  • Always double-check filter fitment before riding. An improperly seated filter allows unfiltered air into the engine, risking major engine wear.
  • The 701 airbox design is compact. Reinstall the cover carefully to avoid pinching the filter or trapping dust inside.
  • If upgrading to a high-flow reusable filter, check for compatibility with your bike's fuel mapping and consider a tune; increased airflow can lean out mixture on highly tuned engines.

For top-tier OEM and high-performance filters, always select parts specifically designed for your exact make, model, and year through MotoSport.com—your source for reliable, race-ready upgrades and expert knowledge.
