PGO X-Hot
Brake fluid capacity & service interval
PGO X-Hot uses brake fluid with a capacity range between min and max. Service intervals require a change every 24 months. The data covers 3 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| X-Hot 150, BF2-150 (2010- ) |
|
| X-Hot 125, BF2-125 (2008- ) |
|
| X-Hot 50, BF2-50 (2008- ) |

Additional Notes
- All three X-Hot variants — the 50, 125, and 150 — share a hydraulic brake system, which means brake fluid is contained within a closed circuit and must be maintained between the reservoir's minimum and maximum markers rather than filled to a fixed volume.
- The PGO X-Hot 125 (BF2-125) and X-Hot 50 (BF2-50) both carry a starting year of 2008, while the X-Hot 150 (BF2-150) has a starting year of 2010.
- A 24-month change interval applies to all three variants under normal use conditions, meaning brake fluid is replaced on a time-based schedule regardless of mileage accumulated within that period.
- The 24-month interval is consistent across the 50cc, 125cc, and 150cc engine displacements, indicating no variation in brake fluid service frequency among the different X-Hot configurations.
- Brake fluid absorbs moisture over time through a process called hygroscopic absorption, which lowers its boiling point and reduces braking effectiveness — the 24-month interval addresses this degradation regardless of how much the fluid level has changed visually.
- The "between min and max" fill specification means there is no single precise capacity figure for a service fill; the correct level falls within a defined range marked on the reservoir, which is standard practice for hydraulic brake systems on scooters of this type.
