Honda NSR

Coolant capacity & service interval

Honda NSR coolant capacity ranges from 0,7 to 1,1 liters. Service intervals include checks every 8000 km or 12 months and fluid changes every 24 months. The data covers 2 configurations.

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

Additional Notes

  • The Honda NSR 125 cooling system holds 1.1 liters of coolant, while the NSR 50-2 holds 0.7 liters — a difference of 0.4 liters that reflects the larger displacement and greater thermal load of the 125cc engine relative to the 50cc unit.
  • Both the NSR 125 (1997-2000) and NSR 50-2 (1989-1999) share a coolant check interval of 8,000 km or 12 months under normal use conditions, whichever comes first.
  • The coolant change interval for both configurations is set at 24 months under normal use, meaning the replacement cycle is time-based rather than mileage-driven.
  • The 24-month change interval is twice the length of the 12-month check interval, indicating that the check schedule is intended to monitor coolant condition and level between full drain-and-fill services.
