37-689: Original Kart , commonly abbreviated as OK , is a kart racing class for drivers aged 14 and over, sanctioned by the CIK-FIA . OK is the primary direct-drive class in FIA championships . The class was originally called Intercontinental A ( ICA ), first introduced in 1981 at the European Championship as a secondary direct-drive class to Formula K . The class was first contested at the World Cup in 2006. In 2007—after 26 seasons of racing—ICA
74-677: A centrifugal clutch . The engine was limited to 15,000 rpm . In 2010, karts of the KF2 category were mandated at the Karting World Championship as the primary direct-drive category, alongside the European Championship, replacing KF1 in both. KF1 returned to the World Championship in 2011 and 2012, reverting KF2 back to World Cup status, but met its demise at the end of the 2012 season. With
111-565: A final which last 20 minutes or more, with a variety of point scoring calculations to determine the event's overall winner. Typical duration does not normally exceed 25 minutes. Here, speed and successful passing is of the most importance. It normally occurs in the format of qualifying, one to three heats and a final race for trophy positions. Sprint Racing in the United States and Canada are held at three primary levels, club racing (local races at purpose-built tracks), regional racing - like
148-474: A light and heavy category. Many people race worldwide in Spec series such as X30 125cc (a TaG class). As in other disciplines in motorsports, a license is required to drive a racing kart in competition. The licenses, issued by governing bodies, are provided by clubs or associations. Basic insurance coverage is usually included in the licence annual fee. In some countries, such as France , regulations require
185-508: A motorsport in itself, it is one of the sports regulated by FIA (under the name of CIK ), permitting licensed racing for anyone from the age of 8 onward. In the United States, there is not as much FIA involvement; instead, many organizations regulate racing, such as the IKF ( International Kart Federation ), WKA ( World Karting Association ), KART (Karters of America Racing Triad), USPKS (United States Pro Karting Series) SKUSA (SuperKartsUSA). In
222-412: A personal computer equipped with a data analysis software. More sophisticated systems allow for more information such as lateral and longitudinal acceleration ( g-force ), throttle position, steering wheel position and brake pressure. Kart racing is generally accepted as the most economical form of motorsport available on four wheels. As a free-time activity, it can be performed by almost anybody, and as
259-606: A stiffer chassis is preferable, while in wet or other poor traction conditions, a more flexible chassis may work better. Temperature of the track can also affect handling and may prompt additional chassis adjustments. The best chassis allow for stiffening bars at the rear, front and side to be added or removed according to race conditions. Braking is achieved by a disc brake mounted on the rear axle. Front disc brakes are used in most shifter kart classes and are increasingly popular in other classes; however, certain classes do not allow them. Shifter karts have dual master cylinders, one for
296-421: A transmission in the automotive power train or drive train. The transmission can: Karts do not have a differential . The lack of a differential means that one rear tire must slide while cornering. This is achieved by designing the chassis so that the inside rear tire lifts up slightly when the kart turns the corner. This allows the tire to lose some of its grip and slide or lift off the ground completely. Power
333-734: Is a motorsport discipline using open-wheel , four-wheeled vehicles known as go-karts or shifter karts. They are usually raced on scaled-down circuits , although some professional kart races are also held on full-size motorsport circuits. Karting is commonly perceived as the stepping stone to the higher ranks of motorsports, with most Formula One drivers—including Ayrton Senna , Michael Schumacher , Fernando Alonso , Kimi Räikkönen , Lewis Hamilton , Sebastian Vettel , Nico Rosberg , and Max Verstappen —having begun their careers in karting. Karts vary widely in speed, and some (known as superkarts ) can reach speeds exceeding 160 kilometres per hour (100 mph), while recreational go-karts intended for
370-963: Is held annually and lasts 24 hours with multiple classes participating. This event is hosted by the Prokart SSS Club near Johannesburg. The most popular class runs the Honda GX390 four-stroke engine, which is both affordable and durable, keeping running costs to a minimum. The Prokart Super Single Series, also known as Prokart SSS, has been running for more than 20 years and has proven to be a very popular entry platform for drivers of all ages who want to get into karting. Many clubs worldwide have taken on four-stroke endurance karting for this reason, since two-stroke karting can be very expensive. Speedway racing takes place on asphalt or clay oval tracks which are normally between 1/10-mile and 1/4-mile long. Tracks primarily consist of two straights and four left-turn corners, few tracks are symmetric and often
407-507: Is no suspension , so chassis have to be flexible enough to work as a suspension and stiff enough not to break or give way on a turn. Kart chassis are classified in the United States as "Open", "Caged", "Straight" or "Offset". All Commission Internationale de Karting –, Fédération Internationale de l'Automobile –, or CIK-FIA-approved chassis are "Straight" and "Open". The stiffness of the chassis enables different handling characteristics for different circumstances. Typically, for dry conditions,

Wheels and tires are much smaller than those used on a normal car. Wheels are made of magnesium alloy, aluminum , or composite materials . Tires can support cornering forces in excess of 2 g (20 m/s²), depending on chassis, engine, and motor setup . Some car tire manufacturers, such as MG Bridgestone , Dunlop , and Maxxis make tires for karts. There are also specific kart tire manufacturers, which include MG, Vega, MOJO, LeCont, Cobra, Hoosier and Burris. Similarly to other motorsports, kart tires have different types for use appropriate to track conditions: As in other motor sports, several data acquisition systems have been developed for kart racing. These systems allow

Their ratio must be adapted to the track configuration to obtain the most performance from the engine. In the early days, karts were direct drive, requiring push starts. The inconvenience of that configuration led to the centrifugal clutch for the club level classes. Dry centrifugal clutches are now used in many categories; Rotax Max
555-524: The CIK-FIA decided to replace the 100 cc water-cooled two-stroke ICA engines with 125 cc Touch-and-Go (TaG) water-cooled two-stroke KF2 engines, producing 34–36 hp (25–27 kW). Now the secondary class to KF1 —which had replaced Formula A —the KF2 class karts used hand-operated front brakes via a lever. The chassis had to be CIK-approved, with a minimum weight of 160 kg and 158 kg for national and international events, respectively. KF2 karts were equipped with an electric starter and

851-749: The United States. Additionally, there are street races where races take place on city streets on temporary circuits like some of the IndyCar races. Endurance races last for an extended period, ranging from 30 minutes up to 24 hours or more, for one or more drivers. In general, consistency, reliability, and pit strategy is of greater importance than all out speed. Called "enduro" racing in the United States, most WKA and IKF sanctioned events typically last 30 minutes (sprint enduro) or 45 minutes (laydown enduro) and are run continuously without pit stops. Enduro events are held on full-size road racing circuits that are usually between 1.5 and 4 miles in length. As well as
