Additional Notes
- The Yamaha Nytro ER, RS90 and Nytro RS90N share an identical cooling system capacity of 4.8 liters for the 2007-2008 model years, indicating the same cooling circuit architecture across those two configurations despite their different designations.
- The 4.8-liter figure represents a full cooling system fill, accounting for the radiator, hoses, reservoir, and engine passages collectively rather than a partial or drain-and-refill service volume.
- The Nytro MTX SE 153 (FX10M53S) and MTX SE 162 (FX10M62S) both carry a 4.9-liter cooling system capacity for the 2010 model year, a slight increase of 0.1 liter over the 2007-2008 RS90-based models.
- The 0.1-liter difference between the 2007-2008 models at 4.8 liters and the 2010 MTX SE variants at 4.9 liters likely reflects minor changes in cooling circuit volume, such as revised hose routing or reservoir sizing associated with the mountain-oriented MTX SE platform.
- All four configurations carry a normal use condition designation, meaning the stated capacities apply to standard operating environments without a separate severe-use or first-fill distinction.
- The MTX SE 153 and MTX SE 162 designations refer to track lengths of 153 and 162 inches respectively, and both share the same 4.9-liter coolant capacity, indicating the extended track length on the 162 does not alter the cooling system volume.
