You get more than we do, because here in the US we've got a flexible bladder inside the gas tank. The gas fills the bladder, so it holds less. And in cold weather the bag shrinks, and holds even less. A few people have reported 500 miles. Others, including myself, prefer to play it safe and fill the tank long before it's empty. I don't believe I've ever gone 400 miles. I don't need to.
