Additional Notes
- The Triumph Speed 400 cooling system holds 1.2 liters of coolant, a figure that reflects the total system fill volume for the liquid-cooled single-cylinder engine.
- A 48-month service interval applies to the coolant change under normal use conditions, placing the Speed 400 in a category of machines where extended-life coolant formulations are typically assumed.
- The 1.2-liter capacity is consistent with a compact single-cylinder cooling circuit, where the radiator, passages, and reservoir together account for a relatively modest total volume compared to multi-cylinder configurations.
