if you want fuel economy go get a little vespa scooter or something.

but the best thing to do is fill your tank and if your machine has an odo. or get a gps and just ride it like you normally would and see how many miles you get off a tank excluding reserve. but if your trying to figure out har far you can get on a tank if your planning a long trip i have seen flat tanks that go on the front or rear cargo rack you can use that as a back up
