Go-kart

A go-kart, also written as go-cart (often referred to as simply a kart), is a type of open-wheel car. Go-karts come in all shapes and forms, from motor less models to high-powered racing machines, some, like Superkarts, being able to beat racing cars or motorcycles on long circuits.

Gravity racers, usually referred to as Soap Box Derby carts, are the simplest type of go-karts. They are propelled by gravity, with some races taking place down a single hill.

Recreational karts can be powered by four-stroke engines or electric motors, while racing karts use a two-stroke or rarely a higher powered four-stroke engines. Most of them are single seater but some 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 20 hp.

Besides traditional kart racing, many commercial enterprises offer karts for rent, often called "recreational" or "concession" karts. The tracks can be indoor or outdoor. Karts are rented by sessions (usually from 10 to 30 minutes), they use sturdy chassis completed with dedicated bodywork providing driver safety. Most of these enterprises use an "Arrive and Drive" format which provide customers with all the safety gear (helmets, gloves and driver outfits) where necessary and allow them to show up any time to race at a reasonable price, without the hassle of owning one's own equipment and gear.

Outdoor tracks can offer low speed karts strictly for amusement (dedicated chassis equipped with low powered four-stroke engines or electric motors), to faster, more powerful karts similar to a racing kart (powered by four-stroke engines up to 15 hp and more rarely by 2-stroke engines) but designed to be more robust for rental use. Typically, these outdoor tracks may also be used for traditional kart races.

Indoor kart tracks can be found in many large cities in different parts of the world. These tracks are often located in refurbished factories or warehouses and are typically shorter than traditional outdoor tracks. Indoor karts are typically powered by a four-stroke gasoline engine producing anywhere from 5 to 13 horsepower, or sometimes by an electric motor. Many tracks offer competitive races and leagues. At the top level, an Indoor Karting World Championship (IKWC) exists.
