Additional Notes

  • The Kawasaki GPZ 1100 / ZX1100 (1994-1997) carries the largest cooling system capacity across the GPZ lineup at 3.4 liters, reflecting the greater thermal demands of a larger displacement engine and a correspondingly larger radiator circuit.
  • The GPZ 1000 RX (1986-1989) holds 3.1 liters of coolant, a figure that falls between the mid-displacement and large-displacement models and applies to a normal use condition with a change interval set at 24 months only, without a distance-based threshold.
  • The GPZ 750 R (1984-1989) has a cooling system capacity of 2.9 liters, also paired with a 24-month-only change interval under normal use, placing it in the same interval structure as the GPZ 1000 RX despite the difference in capacity.
  • Both the GPZ 600 (1985-1989) and the GPZ 900 R (1984-1993) share a 2-liter cooling system capacity, though the GPZ 600 specifies a dual-threshold interval of 30,000 km or 24 months, while the GPZ 900 R carries only the 24-month interval.
  • The GPZ 500 S shows a consistent 1.8-liter capacity across two distinct production periods, 1986-1994 and 1994-2004, making it the smallest cooling system volume in the GPZ range covered by these specifications.
  • The 1994-2004 GPZ 500 S introduces a distance-based threshold of 30,000 km alongside the 24-month interval, whereas the earlier 1986-1994 version specifies only the 24-month change interval, indicating a revision to service scheduling between the two periods.
  • The GPZ 1100 / ZX1100 is the only model in the specifications with a 25,000 km distance threshold, a figure lower than the 30,000 km used for the GPZ 600 and the later GPZ 500 S, paired with the same 24-month time limit.
