5. Maintenance
Regular maintenance is crucial for the longevity and safe operation of your X-PRO X19 Dirt Bike.
- First Oil Change: It is highly recommended to change the engine oil after the first hour of operation to remove any manufacturing debris. Subsequently, follow the manufacturer's recommended oil change intervals.

- Brakes: Inspect brake pads for wear and check brake fluid levels (if applicable). Ensure brakes are functioning correctly.
- Tires: Check tire pressure before each ride. Inspect tires for wear and damage.
