Kawasaki Ninja ZX-4

Coolant capacity & service interval

Kawasaki Ninja ZX-4 requires coolant with a capacity of 2 liters. Service intervals occur every 36000 km or 36 months. The data covers 3 configurations.

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

Additional Notes

  • The Kawasaki Ninja ZX-4 cooling system capacity is 2 liters across all three variants covered in the specifications: the ZX-4R, the ZX-4RR, and the ZX-4RR KRT Edition.
  • A 2-liter cooling system capacity is relatively modest and consistent with a compact inline-four motorcycle engine, where the coolant volume reflects the size of the water jacket surrounding the cylinder block and head.
  • The change interval for all three variants is set at 36,000 km or 36 months, whichever comes first, under normal use conditions.
  • The 36-month time limit means coolant replacement is due after three years regardless of mileage, since coolant degrades chemically over time even when a vehicle sees low use.
  • The ZX-4R, ZX-4RR, and ZX-4RR KRT Edition share an identical 2-liter capacity and the same 36,000 km / 36-month service interval, indicating no variation in cooling system specifications across the trim levels represented in the data.
  • All three variants carry the ZX400SP model code designation, and all share the same cooling system specifications, suggesting the underlying engine and cooling architecture is common across the lineup starting from 2023.
