Additional Notes

  • The Yamaha Niken MXT850 covering 2018-2022 and the Niken GT MXT850D covering 2019-2022 share an identical main cooling system capacity of 1.93 liters, indicating a common engine cooling circuit across both variants.
  • A separate reservoir capacity of 0.25 liters is specified alongside the 1.93-liter figure, reflecting the distinction between the full system fill volume and the overflow or expansion tank volume.
  • The 1.93-liter main capacity represents a service fill value, meaning the volume required when refilling the cooling system during routine maintenance rather than a complete overhaul or dry-fill scenario.
  • The Niken GT MXT850D carries a second specification entry starting from 2022, with a main capacity of 1.93 liters and a reservoir of 0.25 liters, identical to the earlier 2019-2022 entry for the same variant.
  • All three specification rows carry a normal use condition, meaning the 36-month change interval applies to standard operating environments rather than severe or demanding riding conditions.
  • A 36-month coolant change interval is consistent across the MXT850 and MXT850D variants, placing the service cycle on a calendar-based schedule rather than a mileage-based one.
