Derbi GP1
Brake fluid capacity & service interval
Derbi GP1 uses brake fluid with a capacity range between min and max. Service intervals require a change every 24 months. The data covers 5 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- Across all GP1 variants, brake fluid level is specified as a range rather than a fixed volume, with the reservoir kept between the minimum and maximum marks on the hydraulic brake system.
- The 24-month change interval applies uniformly across all GP1 configurations under normal use conditions, reflecting the standard practice of replacing brake fluid on a time-based schedule rather than a mileage-based one.
- Time-based brake fluid replacement accounts for the hygroscopic nature of brake fluid, which absorbs moisture from the atmosphere over time and lowers the boiling point of the fluid regardless of distance traveled.
- The Derbi GP1 50 carries the widest model year span in the specifications, covering 2002-2012, while the 125 and 250 variants share a narrower window beginning in 2006.
- The GP1 250 appears under two separate year range entries, 2006-2007 and 2007-2009, both specifying identical brake fluid level and interval requirements under normal use.
- The GP1 250i (2007-2009) is listed as a distinct variant from the GP1 250 of the same period, indicating a separate configuration, though both share the same hydraulic brake system fluid level specification and 24-month change interval.
