With a motorcycle it's a little different. Motorcycles generally don't have a fuel gauge. Mine has an idiot light that comes on about halfway through the 4 gallon tank. What I do is reset the trip odometer on every fill, and estimate the tank's fullness from the mileage (I get about 40 mpg using past data). I do generally fill it by the 1/4 point, because this method is approximate, and I like the secure feeling of a fullish tank. Do not fill it brim full in warm weather, because the fuel expands some in the heat and may overflow.
My bike doesn't have a fuel gauge and only holds 2 gallons, but I get ~65-75 mpg in the warmer months and ~55-60 mpg in the now-like months. I don't have any lights to indicate when my fuel is down, so I set the trip odometer at every fill and watch the regular odometer just in case the trip odometer gets reset by accident - and I like to (therefore) fill the tank when I reach some easy to remember & easy to sum up number on the regular odometer (like xyz,125 and then at xyz,250 and then at xyz,275, etc).
(My fall back low fuel warning system is that when the ride gets a little rough / the engine starts to cut out, I switch to the 1/4 gal of reserve by throwing over the petcock...and then I know I have to should really get gas before my next commute or commute+return.)
