Shop parts for a 2015 Husqvarna TC85BW Dirt Bike.
Your 2015 Husqvarna TC85BW is engineered for top-tier performance on motocross tracks, but its high-revving engine and off-road design mean regular air filter maintenance is absolutely critical. A clean air filter keeps abrasive dirt and debris out of the engine—essential to maximize power output, reduce wear, and prevent costly repairs. Follow MotoSport's proprietary guide to keep your TC85BW breathing free and strong, using parts and supplies trusted by MotoSport veterans.
Why Air Filter Maintenance on the TC85BW Matters
- Dirt bike environments push the air filtration system to its limits with dust, sand, and mud.
- Neglecting filter service can lead to premature engine damage.
- The 2015 TC85BW's high-compression 2-stroke engine is especially sensitive to air qualityregular filter care preserves its throttle response and reliability.
How Often Should You Service the Air Filter?
- Check the filter after every ride in dusty conditions and at least every 20 operating hours under normal use.
- Immediately clean if heavy mud or dust is present; replace if damaged or excessively worn.
- Include the air filter in all scheduled service intervals as outlined by Husqvarna® recommendations.
2015 TC85BW Air Filter Removal Instructions
- Undo the seat bolt and carefully lift the seat from the frame.
- Access the airbox and unclip the filter cage release (take care not to disturb surrounding dirt that could drop into the intake).
- Gently remove the air filter by hand, keeping it upright to avoid dust spilling inwards.
Proper Cleaning Procedure (MotoSport Method)
- Tap loose debris from the filter away from the intake side.
- Submerge the filter in a dedicated filter cleaner solution–never gasoline or harsh solvents.
- Work solution through the foam gently. Rinse with cool water until clear, squeezing (not wringing) to avoid tearing the foam matrix.
- Allow the filter to air dry in a contaminant-free environment.
Oiling & Reinstallation
- Once the filter is dry, apply a high-quality foam filter oil evenly. Massage oil throughout so every pore is covered but not saturated.
- Check the filter cage for cracks or sharp edges that could puncture the new foam.
- Reinstall the filter on the cage, ensuring a full and uniform seal around the airbox.
- Reattach the seat securely before your next ride.
Replacement Recommendations
- Replace the air filter at least annually, or immediately if any tears, holes, or crumbling foam are found.
- Inspect the airbox gasket and filter cage during every service; both are critical for sealing performance.
- For riders using wash covers, always remove before riding and inspect the air intake path for water or residual cleaner.
Model-Specific Owner Notes
- Your 2015 TC85BW features a compact airbox and unique cage design, so always confirm the filter is properly seated with no gaps–even a small leak can cause engine scoring in this model.
- Due to the TC85BW's high-rpm 2-stroke engine, dirty or poorly oiled filters have an outsized impact on reed valve wear and top-end longevity.
- Oiling should be consistent but sparse at the intake lip: excess oil can cause bogging in this small-displacement 2-stroke.
Regular, careful air filter service ensures your 2015 Husqvarna TC85BW delivers reliable power and top performance every time you ride. Use high-quality replacement parts from MotoSport and never compromise on the seal of your airbox for the best protection and engine life.
