Honda CH
Coolant capacity & service interval
Honda CH uses coolant with a capacity range of 1,1 to 1,4 liters. Service intervals require a change every 24 months. The data covers 2 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| CH 125 (1985-1990) |

Additional Notes
- The Honda CH 125 cooling system holds 1.1 liters of coolant, while the CH 250 requires a notably larger 1.4 liters, reflecting the displacement difference between the two engine configurations.
- Both the CH 125 and CH 250 share a 24-month coolant change interval under normal use conditions, placing each on a two-year service cycle regardless of mileage accumulated within that period.
- The CH 125 cooling system specification applies to model years 1985-1990, whereas the CH 250 specification covers 1984-1989, meaning the two variants do not share an identical production window despite overlapping for much of the period.
- A 1.1-liter coolant capacity on the CH 125 is consistent with a small-displacement liquid-cooled scooter engine, where the cooling circuit is compact relative to larger motorcycle platforms.
- The 1.4-liter figure on the CH 250 represents a service fill capacity for the cooling system as a whole, indicating the total volume required to properly replenish the circuit during a standard coolant change.
