Shop parts for a 2014 Husqvarna TC125 Dirt Bike.

The 2014 Husqvarna TC125 stands out in the 125cc class for its lightweight agility & competitive powercurve. Regular air filter maintenance is essential for keeping your TC125 running at peak performance and preventing internal engine damage. The TC125 typically comes equipped with a washable cotton gauze air filter or can use aftermarket dual-stage foam filters .

Key Features of the 2014 TC125 Air Filter

  • Washable and reusable (OEM cotton gauze type) – 7.75 inches outside length for optimal air intake.
  • Performance foam dual-stage (aftermarket) – uses inner & outer layers for enhanced filtration and longevity .
  • Key for sand, dust, and off-road environments – especially important for motocross terrain.

Before You Begin: What Owners Should Know

  • This model is designed with an easy-access air filter cage for quick removal & installation.
  • Use only filters recommended for 2014 TC125 for a proper seal & protection. Foam or cotton gauze styles are both compatible.
  • Running a dirty filter can drastically reduce power and lead to major engine damage — clean or replace as dictated by riding conditions (after every ride in heavy dust or mud).

How to Clean Your Air Filter

  1. Remove seat – then carefully extract the filter from the airbox. Inspect for excess dirt or damage before proceeding.
  2. If using a foam filter:
    • Wash gently in a dedicated air filter cleaner or mild detergent, rinsing until water is clear.
    • Squeeze – do not wring – to remove water. Air dry completely before oiling.
    • Apply foam air filter oil liberally, working it throughout the filter for full coverage.
  3. If using OEM cotton gauze filter:
    • Spray with air filter cleaner & allow to soak for a few minutes.
    • Rinse from the clean side out to avoid pushing dirt further into the filter fibers.
    • Let dry completely before reinstalling.
  4. Inspect the filter cage – ensure no dirt is present in the airbox. Wipe surfaces clean.
  5. Reinstall the filter – check for secure fit to prevent air leaks.

When to Replace Your Air Filter

  • Replace the filter anytime it becomes excessively dirty, damaged, or fails to fit securely.
  • Full replacement is recommended every season — more often for heavy riders or those riding in sandy, muddy, or extreme conditions.

Expert Tips for 2014 Husqvarna TC125 Owners

  • Carry a spare, pre-oiled filter on race days for ultra-fast swaps.
  • The TC125 airbox is engineered for minimal restriction – check regularly for cracks or wear on sealing surfaces.
  • Seal all mating surfaces with a thin layer of filter grease for extra insurance against dirt intrusion.
  • Record each cleaning & replacement in your maintenance log for optimal engine health.
