As per ARAI, the average of R1200 GS Adventure is 16 kmpl. With a fuel tank capacity of 33 litres, this bike can go upto 432 kms on full tank. While ARAI mileage figures are achieved under ideal test conditions, the real mileage may vary because of driving conditions and riding habits of riders.
So my overall fuel tank capacity is about 5.5 gallons. I consistently get between 42 and 44 miles per gallon. If I'm going slower or riding downhill A LOT, I can get as high as 59 mpg. I pressed it once and got over 250 miles out of one tank. The dash displayed 9 miles remaining when I fueled up.
A modern GS has more of an " over drive " than a 6th gear. If attempting to get the most miles from a gallon of fuel the 6th gear is seldom useful except with a tail wind when it comes to pure range. One can usually get more miles out of a tank of fuel by dropping to 5th gear and staying under 4k RPM, more like 3500 RPM or so.
