How far can a motorcycle go on a tank of gas?

First off if you know your MPGs and How many gallons your tank holds that's makes it really, really simple. If you don't know either of those well.. there's an easy way to figure it out. Lets Start first with how many gallons your tank can carry. upon approaching E and when the light comes on or anything of that sort, or you notice your tank is just low if you don't have an indicator. Pull up to a gas station, and be sure to put the bike on Reserve ((that way ALL the fuel is used) if you have a reserve switch) and let it run. Be Sure not to take up a spot in the fuel island so others may fuel while you wait. and if your that particular about wasting money don't worry about it. you more than likely have less than a gallon left, under 3 bucks, once the bike dies out be sure to turn it off right away to not lose power as the bike isn't charging itself anymore. Next pull up to a fuel island, open your tank and fill it up. Most bikes are under 5 gallons but some can have massive tanks, the largest I've seen is 8. So, know you know how many gallons. Now, go out 10 miles and 10 miles back to the gas station, totalling 20 miles on the bike, and fill her up again. Now lets say you put 4.2 gallons in the first time, no lets say you put in 1/3 of a gallon of gas. You went 20 miles, on 1/3 gallon, meaning that your bike gets 60 MPG. so, on a bike that gets 60 MPG with a 4.2 gallon tank means that your bike can go 252 miles before being out of gas. So, this is where a trip meter comes in handy if you don't have a fuel indicator of any kind. around 230 miles you'll have about 20 miles to find a gas station. or if your planning your route, be sure to have at least ONE gas station every 200 miles.
