Additional Notes

  • The Suzuki VZ800/M800 Intruder and M50 Boulevard cooling system holds 1.75 liters of coolant across both the K5-K9 (2005-2010) and K10 (2010- ) generations, indicating a consistent system volume despite the model year transition.
  • The M90 Boulevard / VZ1500 / M1500 Intruder K9 carries a noticeably larger cooling system capacity of 2.65 liters, reflecting the greater thermal demands of the 1500cc engine compared to the 800cc platform.
  • All three configurations share a 24-month coolant change interval under normal use conditions, meaning the service schedule is time-based rather than mileage-driven for the cooling system.
  • The 1.75-liter capacity listed for the M50 Boulevard / VZ800 K5-K9 represents a service fill figure for the cooling system, applicable during routine maintenance rather than a full overhaul drain.
  • The 0.90-liter difference between the 800cc and 1500cc platform capacities (1.75 liters versus 2.65 liters) corresponds directly to the larger engine displacement and the increased coolant volume needed to regulate operating temperatures in the bigger powerplant.
