A little info about Go Carts and Dune Buggys!
A go-kart is a four-wheeled vehicle which is usually very small, able to accommodate only one person, the driver, though a few models accommodate a passenger. Go-karts come in a wide variety of variants, ranging from motorless karts to high-powered variants, and a single variant called a �Superkart,� which has enough power to beat a racing car head-on in long circuits. Some models, specifically those created for amusement parks, use a 4-stroke engine or electric-powered motors, while go-karts designed for racing usually boast either a small 2-stroke or a 4-stroke engine.
A variant of the go-kart is the dune buggy, which is a recreational vehicle built for use on sandy areas like sand dunes and beaches. To increase the power-to-weight ratio of the vehicle, the manufacturer makes the buggy lighter or increases the engine power, sometimes a combination of both. Lightening the vehicle is achieved by mounting the engine on an open chassis, and some other modifications which give the buggy an open-air look. A dune buggy suitable for use on open sand is called a �sandrail�. But more recently, �off-road go karts� were designed simply by swapping out the sand-use tires with all-terrain tires, allowing the kart to ride smoothly on a much wider variety of land terrain, even on difficult surfaces.
The overall frame of the kart is made from steel tubing, which gives it a sturdy structure as well as making it easier to construct. Depending on the frame, performance needs and suspension, the engine size can vary from 50 cc for small, light buggies to 7-liter engines and up, which are designed for professional racing. They can also have automatic or manual transmission.
