Additional Notes
- The Yamaha YP Majesty (USA) coolant system specifications cover two distinct configurations across the 2005-2014 model span, with the 2005-2011 and 2012-2014 variants carrying different capacity details.
- For the 2005-2011 YP 400 Majesty, the cooling system fill level is expressed as a range between a minimum and maximum mark rather than a fixed volume, meaning service is performed by topping up to the appropriate level indicator rather than measuring a precise quantity.
- The 2012-2014 YP 400 Majesty carries a stated cooling system capacity of 1.89 liters, with an additional reservoir volume on top of that figure, giving a more defined total fill reference compared to the earlier configuration.
- The 1.89-liter figure for the 2012-2014 model represents the primary system volume, while the separate reservoir adds to the overall coolant quantity held in the circuit, a common arrangement in liquid-cooled scooter designs where overflow and expansion are managed independently.
- Both the 2005-2011 and 2012-2014 configurations share an identical change interval of 36 months under normal use conditions, placing coolant renewal on a calendar-based schedule rather than a mileage-driven one.
- A 36-month interval tied to normal use conditions reflects the degradation of coolant additives over time, where corrosion inhibitors and pH stabilizers break down regardless of distance traveled, making elapsed time the primary service trigger.
