Shop parts for a 2010 Kawasaki KLX110 Dirt Bike.

The 2010 Kawasaki KLX110 is a beloved entry-level dirt bike known for its durability, compact size, – and approachable power. Maintaining its air filter is crucial to keeping the engine healthy, maximizing performance, and extending the lifespan of this model. Below you’ll find MotoSport’s exclusive method for cleaning and replacing the air filter, tailored for the KLX110’s specific design features.

Why Air Filter Maintenance Matters for Your KLX110

  • Engine Longevity: Prevents dirt and debris from causing premature engine wear.
  • Performance: Ensures optimal airflow for acceleration and horsepower.
  • Fuel Efficiency: A clean filter helps keep the bike’s fuel mix proper, avoiding excess consumption.

Unique Notes for the 2010 KLX110 Model

  • KLX110 uses a foam dual-stage filter, meaning both the coarse outer layer and fine inner layer trap particles. The two layers are fused, preventing dirt from working between them.
  • The filter is accessible under the seat, designed to be removed without specialized tools.
  • Over-oiling can restrict airflow—the KLX110’s filter requires an even, light application of filter oil.

Step-by-Step: Cleaning the Air Filter

  1. Remove the Seat: Use the side bolts to lift the seat off; set aside.
  2. Extract the Filter: Pull the filter from the airbox. Inspect for tears, hard spots, or excessive grime.
  3. Initial Cleaning: Tap gently to dislodge loose dust. Don’t use compressed air, which can damage the foam.
  4. Wash: Submerge the filter in a container of a mild, biodegradable cleaner or dedicated foam filter cleaner. Squeeze gently to work out dirt & oil until the cleaner runs clear. Avoid wringing or stretching the foam.
  5. Rinse: Use fresh water to rinse thoroughly. Squeeze excess water out.
  6. Dry: Let the filter air-dry completely away from sunlight and high heat sources.
  7. Oil: Apply a high-quality foam filter oil, making sure the filter is evenly coated but not saturated. Squeeze and move the filter in your hands to distribute.
  8. Reinstall: Place the filter firmly back in the airbox, ensuring a proper seal. Replace the seat.

Replacement Guide

  • If the filter shows signs of damage (rips, hardening, or excessive wear), replacement is necessary. Top choices for the KLX110 include Twin Air–with dual-stage construction–and other OEM-specific foam filters.
  • Check part compatibility: The filter must fit the 2010 KLX110 airbox precisely to avoid leaks and engine contamination.
  • MotoSport recommends inspecting the filter every 5-10 hours of riding – more frequently if riding in dusty or sandy terrain.

Pro Tips from MotoSport

  • Always keep a spare clean & oiled filter in a resealable bag for quick swaps during extended ride days.
  • Seal the airbox properly after reinstallation to avoid air leaks, which can reduce engine performance.
  • Do not substitute KLX110 filters with similar-looking filters from other bikes. Design tolerances make a difference for engine protection.

MotoSport’s proprietary process is designed specifically for the KLX110—follow it for optimal performance and long-term reliability.
