Additional Notes
- The BMW C1 and C1 200 (2000-2005) share identical cooling system capacities: 1.25 liters for the main circuit and 0.2 liters for the reservoir.
- A 1.25-liter main circuit capacity is relatively modest, consistent with the small single-cylinder engine displacement found in the C1 and C1 200 scooters.
- The 0.2-liter reservoir on the C1 and C1 200 represents an overflow or expansion tank, separate from the primary cooling circuit volume.
- The C1 and C1 200 specify a 24-month coolant change interval under normal use conditions, a schedule tied to the degradation of corrosion inhibitors in the coolant over time rather than mileage.
- The C650 GT (2012-2014) and C650 GT (2015-2022) both specify coolant level maintenance between the minimum and maximum marks rather than a fixed fill volume, indicating a top-up approach rather than a measured service fill.
- The C650 Sport (2015-2022) follows the same min-to-max level specification as the C650 GT, reflecting a shared approach to coolant servicing across the larger-displacement C650 platform.
- The absence of a fixed liter value for the C650 GT and C650 Sport contrasts with the precise capacity figures given for the C1 series, suggesting different service methodologies between the two generations of BMW C-series scooters.
