A dirt bike rider flies off a ramp and soars the length of a football field. He lands safely with a thud. In wild stunts like this the technology of an off-road vehicle can mean the difference between life and death. Off-road vehicles need super-tough suspension systems. Some ATVs have tires without air to battle rugged terrain without going flat. The SkyRunner dune buggy even has a parachute that can lift it into the air Take young readers on a journey through the technology that makes off-road vehicles so amazing.
