A go-kart (sometimes known as a "go-cart" or just kart) is a small four-wheeled vehicle. Go-karts come in all shapes and forms, from motorless models to high-powered racing machines, some, like Superkarts, being able to beat racing cars on long circuits.
Amusement park go-karts can be powered by 4-stroke engines or electric motors, while racing karts use small 2-stroke or 4-stroke engines. Most of them are single seater but recreational models can sometimes accommodate a passenger.
In some countries, go-karts can be licensed for use on public roads. Typically there are some restrictions, e.g. in the European Union a go-kart on the road needs head light (high/low beam), tail lights, a horn, indicators and a maximum of 20hp.
