Derbi GP1

Coolant capacity & service interval

Derbi GP1 uses coolant with a capacity range of min to max. Service intervals require a change every 24 months. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

GP1 125 (2006-2009)
  • Use: Normal
  • Between min and max.
  • Change 24 months
GP1 250 (2006-2007)
  • Use: Normal
  • Between min and max.
  • Change 24 months

Additional Notes

  • Across all Derbi GP1 variants covered — the 125 and both 250 configurations, plus the 250i — coolant capacity is expressed as a level range rather than a fixed volume, meaning the reservoir or system should be filled to sit between the marked minimum and maximum indicators rather than to a precise measured quantity.
  • A 24-month change interval applies uniformly to all four GP1 configurations under normal use conditions, making coolant renewal a time-based service rather than one tied to mileage or operating hours.
  • The GP1 125, spanning 2006-2009, shares the same coolant service interval and fill method as the larger-displacement 250 variants, despite the difference in engine size.
  • The GP1 250 appears across two overlapping year ranges — 2006-2007 and 2007-2009 — both carrying identical coolant specifications, with 2007 present in each range.
  • The GP1 250i, covering 2007-2009, represents a fuel-injected variant of the 250 and carries the same coolant level and interval specifications as the carbureted GP1 250 of the same period.
