Engines running methanol or other alcohol-based fuels.Gasoline 2-stroke or 4-stroke engines are the most common type, but other types of propulsion are available: Several types are available, as well as differing fuel options. While hobby go-karts depend on gravity for propulsion, racing karts use a small engine. American companies in the shifter kart market include Trackmagic and Margay. TonyKart, Birel and CRG are a few well known examples of the many European manufacturers of race-quality chassis. Professionally raced karts typically weigh 200 to 300 lb (100 to 150 kg). Typically, for dry conditions a stiffer chassis with less flex is better, while in wet or other poor traction conditions, a more flexible chassis is preferable. Caged karts have a roll cage surrounding the driver, and open karts have no roll cage. Kart chassis are also classified as 'open' or 'caged'. Chassis designed for indoor or non-professional racing usually have large bumpers on all four sides, while high speed shifter or direct drive karts have plastic or fiberglass spoilers to improve aerodynamics and crash protection. Chassis construction is normally of a tubular construction, typically steel, with different grades and diameters of tubing as well as their actual configuration offering different amounts of flexibility.

Karts typically have no suspension, and are usually no bigger than is needed to mount a seat for the driver and a small engine. this is called inside wheel lift and is needed as otherwise due to the lack of a differential it would be hard to break the karts forward momentum. Without this, the inside rear wheel of a kart would cause very difficult problems during a turn. The chassis is an extremely important element of the kart, as it must provide, via flex, the equivalent of a rear wheel differential.
