Keeping the air filter on your 2021 Yamaha TTR110 clean – and replacing it whenever needed – is crucial for maintaining engine performance, maximizing longevity, and ensuring reliable starts. This guide from MotoSport walks you through step-by-step air filter service specific to the TTR110, highlighting key model details owners should know.
Why Air Filter Maintenance Matters for Your TTR110
- Dirt bikes operate in dusty environments – riding with a clean filter protects your engine by preventing dirt, sand, and debris from entering the intake.
- TTR110's foam filter is reusable: Clean and re-oil it regularly; only replace it when it is torn, degraded, or unable to seal properly.
- Frequent filter service is especially important after riding in wet, sandy, or silty conditions.
Proprietary MotoSport Step-by-Step Cleaning Instructions
- Park your Yamaha TTR110 on a level surface and let the engine fully cool.
- Remove the seat (two 10mm bolts), then take off the right side panel for easy access to the air box.
- Use a Phillips screwdriver to remove the three screws securing the air filter case cover.
- Gently pull out the foam filter and mesh screen; inspect for tears or deterioration – replace if damaged.
- Wash the foam filter in a dedicated air filter cleaner or mild detergent. Squeeze, don't twist, until clean; rinse thoroughly with warm water (never use gasoline or low flash-point solvents).
- Let the filter air dry completely. Do not use heat (such as a hair dryer), which can damage the foam.
- Once dry, saturate the filter with air filter oil, working thoroughly to cover all surfaces for optimal dust-trapping performance. Squeeze out excess oil. MotoSport recommends sealing the filter in a small, clean bag to distribute oil evenly.
- Reinstall the clean, oiled filter and mesh, ensuring a snug fit in the air box. Carefully reinstall the cover and panels in reverse order.
- Always dispose of old oil, solvents, and filters responsibly – follow local environmental guidelines.
Replacement Guidance
- If the foam is torn, crumbling, or no longer fits tightly, replace with a new OEM-quality filter.
- Check for excessive oil residue, dirt infiltration, or loss of filter structure after every ride in severe dust or mud – more frequent service may be needed.
TTR110-Specific Notes for Owners
- The 2021 TTR110 uses a simple foam filter system – reliable and very easy to clean or replace, ideal for young riders and entry-level maintenance.
- All routine air filter service can be performed with basic hand tools (Phillips screwdrivers, 10mm socket), making it a straightforward DIY project.
- Always check the foam filter for sealing against the air box – poor sealing allows fine dust to bypass and damage the engine.

Recommended Service Intervals
- Consult your owner's manual. In most cases, inspect after every ride and clean at least every 10 engine hours or immediately after heavy dust, sand, or water exposure.
