As implied by name, the Kart is a small low-profile go-kart constructed with the barest of materials and is a one-seater capable of carrying only the driver. The vehicle is usually depicted with bare frame and a frontal bumper, but may also be available with additional matching side skirts. Other features include its rear engine and small racing slicks.
Being very compact, the Kart's low-powered engine is adequate in providing the vehicle with average speed, good acceleration and good mountain climbing, and allows the go-kart to execute sharp turns and brake in very short distances. However, these traits may also work against the maneuverability of the vehicle, as the steering is overly sensitive (thus requiring the player tap the steering controls instead of holding it), and the vehicle's low profile and light weight makes drives onto curbs or crashes into larger, heavier vehicles risky as the vehicle may spin out or flip.
Unusually, being a fully exposed vehicle, the player cannot dismount from the Kart during violent crashes or flips; neither can the player shoot forward, despite the Kart having a clear frontal field of view to do so. This is because the game files have set it as a car instead of a quadbike. This can also be seen when changing radio stations, as CJ acts like he is inside a car.
- The Kart plays the radio station Radio X by default when entered.
- The Kart has the unique ability to be able to drive under larger vehicles, such as the Tanker trailer and Monster, or any other vehicle with high ground clearance.
- The Kart can turn as if "Perfect Handling" cheat is on. However, the cheat still takes the body roll effect from high speeds combined with sharp handling.
- The kart will lose its side bumpers if saved from a garage.
- The Kart is used in the mission Cut Throat Business during the chase of OG Loc.
