Additional Notes
- The Triumph Trident 660 Euro 5 carries a coolant capacity range of 2.2 to 2.36 liters across both the 2020-2023 and 2024 model year variants, with the spread between the lower and upper figures reflecting typical variation between a drain-and-refill service fill and a more complete system flush that recovers fluid from all passages and the reservoir.
- A 36-month change interval applies to the cooling system under normal use conditions for the 2020-2023 Euro 5 specification, meaning the interval is tied to calendar time rather than mileage accumulation.
- The 2024 Euro 5 variant shares the identical 36-month change interval under normal use conditions, as well as the same 2.2 to 2.36 liter capacity window, indicating no revision to the cooling system specification between the two generational designations.
