Largest Fuel Tanks (2026)

Those who have one don't really need one—or at least don't need to stop nearly as often. They can simply keep riding. That used to be a major advantage in the original Dakar Rally. It still matters to truck and bus drivers. And, of course, to marathon riders on two wheels. Welcome to the world of the Iron Butt, where more than 1,000 kilometers (620 miles) in a single day is just another ride—with huge fuel tanks on board.
