The US user manual claims that the regular 1250 GS has 5.3 gallons of ‘usable fuel’ and 1.1 gallon of reserve, for a total of 6.4 gallons. I have noticed in the last few refueling stops were the ‘fuel range’ meter was quite low (~ 20 miles) it took only 4.1 gallons before the gas-station nozzle recoiled and stopped pumping.
