Why Maintaining Your Air Filter Is Important
The air filter prevents dust, dirt, and debris from entering the engine. If neglected, a dirty air filter can:
- Reduce airflow, causing the engine to work harder.
- Decrease fuel efficiency.
- Lead to engine damage due to contaminants.
- Lower overall performance.
Regular maintenance ensures optimal engine performance, better mileage, and a longer lifespan for your bike.
