Simple maths there are- about 9 litres in 2 gallons
So 1 gallon = 4.5 litres
If you set your readout to miles/litre
A reading of 10 gives 45mpg or so
most normal main road cruising will give you 9 to 11
open the throttle will get down to 5 or 6
down hill with the wind behind you - might give you 12or 13
Now this might sound good but remember the bike overreads by up to 10%
You might get 200 miles from a tank - but watch the low fuel warning like a hawk
