OK (karting)
KF2, is a kart racing class for top drivers aged 14 and up. This class used to be called Intercontinental A (ICA) and has changed since January 2007 when CIK-FIA decided to replace the 100 cc water-cooled two-stroke engines with 125 cc Touch-and-Go (TaG) water-cooled two-stroke engines (KF type). The engines produce . The KF2 class karts use hand-operated front brakes via a lever. The chassis must be approved by the CIK-FIA. Minimum weight with driver is 160 kg for national and 158 kg for international events. Karts are equipped with an electric starter and a centrifugal clutch. The engine rpm is limited at 15,000 rpm. It is one of the highest kart classes and is run in both national and continental championships, with the most prestigious being the European Championship and the World Cup. In 2010, karts of the KF2 category were mandated in the Karting World Championship. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kart Racing
Kart racing or karting is a road racing variant of motorsport with open-wheel, four-wheeled vehicles known as go-karts or shifter karts. They are usually raced on kart circuit, 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 of Formula One champions including Sebastian Vettel, Nico Rosberg, Ayrton Senna, Max Verstappen, Lewis Hamilton, Michael Schumacher, Kimi Räikkönen, and Fernando Alonso having begun their careers in karting. Karts vary widely in speed and some (known as superkarts) can reach speeds exceeding , while recreational go-karts intended for the general public may be limited to lower speeds. History American Art Ingels is generally accepted to be the father of karting. A veteran hot rodder and a race car builder at Kurtis Kraft, he built the first kart in Southern California in 1956.

Commission Internationale De Karting
The Commission Internationale de Karting (CIK or CIK-FIA) is the primary international sanctioning body for kart racing. It was founded in 1962, and is headquartered in Paris, France. In 2000, it joined with the FIA. Its most important event is the Karting World Championship. CIK's current president, former Formula One driver Felipe Massa, took office in December 2017. His predecessors were Luigi Macaluso (October 2005 – October 2009), Nicolas Deschaux (October 2009 – October 2010). and Shaikh Abdulla bin Isa Al Khalifa.

Fédération Internationale De L'Automobile
The Fédération Internationale de l'Automobile (FIA; en, International Automobile Federation) is an association established on 20 June 1904 to represent the interests of motoring organisations and motor car users. It is the governing body for many auto racing events, including Formula One. The FIA also promotes road safety around the world. Headquartered at 8 Place de la Concorde, Paris, with offices in Geneva and Valleiry, the FIA consists of 246 member organisations in 145 countries worldwide. Its current president is Mohammed bin Sulayem. The FIA is generally known by its French name or initials, even in non-French-speaking countries, but is occasionally rendered as International Automobile Federation. Its most prominent role is in the licensing and sanctioning of Formula One, World Rally Championship, FIA World Endurance Championship, World Endurance Championship, World Touring Car Cup, FIA World Rallycross Championship, World Rallycross Championship, Formula E, and variou ...

Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later two-s ...

Centrifugal Clutch
A centrifugal clutch is an automatic clutch that uses centrifugal force to operate. The output shaft is disengaged at low rotational speed and engages more as speed increases. It is often used in mopeds, underbones, lawn mowers, go-karts, chainsaws, mini bikes, and some paramotors and boats to keep the engine from stalling when the output shaft is slowed or stopped abruptly, and to remove load when starting and idling. It has been superseded for automobile applications by the fluid coupling and automated manual transmissions. Operation The input of the clutch is connected to the engine crankshaft while the output may drive a shaft, chain, or belt. As engine revolutions per minute increase, weighted arms in the clutch swing outward and force the clutch to engage. The most common types have friction pads or shoes radially mounted that engage the inside of the rim of a housing. On the center shaft, there is an assorted number of extension springs, which connect to a clutch shoe. When ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...

Karting World Championship
The Karting World Championship is a kart racing competition organised by the CIK-FIA. It is held annually since 1964, and is karting's flagship event. The FIA (International Automobile Federation) created the CIK (International Karting Commission) in 1962. The Current President of the Championship is former Formula 1 driver Felipe Massa. The first two World Championships in 1964 and 1965 were held over one final round, there after the world's best kart drivers competed for the title over an extended weekend, from Thursday to Saturday, including free and qualifying practice sessions, qualification heats, a pre-final and a final were common. From 2011 the championship has been disputed over five rounds, each of them in a different country. From 2014 the world championships returned to a single event with one venue each year organizing the CIK-FIA OK and OK Junior World Championships in one weekend and another venue in a different weekend holding the CIK-FIA KZ World Championships ...

KZ1 (karting)
KZ1 is a kart racing class using 125 cc water-cooled two-stroke engines yielding approximately , equipped with a six-speed gearbox. KZ1 is the fastest of the KZ karting racing categories, and technical regulations are similar to KZ2 except that KZ1 allows for the gearbox to be either manual or electro-mechanical as well as the wise use of soft tires. – Article 12, Specific Regulations for KZ2 & KZ1, p. 350 Both engines and chassis must be approved by the CIK- |
Superkart
Superkart is a form of motorsport road racing that uses karts on long circuits. The most obvious difference between a superkart and most other forms of kart is that they have full aerodynamic bodykits as well as having a longer wheel base than sprint chassis and are generally raced on car circuits over 1,500 metres in length. The power unit, most often, but not exclusively two-stroke 250 cc engines, can be specially designed kart engines or production motorcycle engines with either five- or six-speed sequential manual gearboxes. Owing to their high top speed and superb cornering ability, a superkart's aerodynamic bodywork includes a front fairing, larger sidepods, and a rear wing. They use either tires and wheels and most often race on full size auto-racing circuits. The 250 cc superkarts can set faster lap times than much more expensive and technically advanced racing machines. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
