History
the Kart the racing in the streets of in Berlin in 1963
the Art Ingels is generally accepted to be the father of karting, A veteran hot rodder, a race car builder at Kurtis Kraft, he built the first kart in Southern Cali, nia in 1956, Karting has rapidly spread to other countries,, currently has a large following in Europe,
< br /> The first kart manufacturer was an American company, Go Kart Manufacturing Co, 1958), McCulloch was the first company, in 1959, to produce engines, karts, Its first engine, Brett Favre viking jersey, the McCulloch MC-10, was an adapted chainsaw 2-stroke engine, Later, in the 1960s, motorcycle engines were also adapted, kart use, be, e dedied manufacturers, especially in Italy IAME), started to build engines, the sport,
Components
Chassis
Rear view of a current CIK-FIA approved race kart equipped with KF engine
The chassis, made of steel tube , There is no suspension there, e chassis have to be flexible enough to work as a suspension, stiff enough not to break or give way on a turn, Kart chassis, classified in the USA as Open Caged Straight r Offset All CIK-FIA approved chassis, Straight Open
Open karts have no roll cage,
Caged karts have a roll cage surrounding the driver; they, mostly used on dirt tracks,
In Straight chassis the driver sits in the center, Straight chassis, used, sprint racing,
In Offset chassis the driver sits on the left side, Offset chassis, used, left-turn-only speedway racing,
The stiffness of the chassis enables different h, ling characteristics, different circumstances, Typically,, dry conditions a stiffer chassis is preferable, while in wet or other poor traction conditions, a more flexible chassis may work better, The best chassis allow, stiffening bars at the rear, front, side to be added or removed according to race conditions,
< br /> Braking is achieved by a disc brake mounted on the rear axle, Front disc brakes, increasingly popular; however, certain classes do not allow them,
Professionally raced karts typically weigh 165 to 175lb 75 to 79, kg), complete without driver, Avanti, Tony Kart, Trulli, Birel, CRG, Gillard, Intrepid, Kosmic, Zanardi or FA Kart, a few well known examples of the many European manufacturers of race-quality chassis, Margay is an American company producing kart chassis,
Engines
Amusement park go-karts can be powered by 4-stroke engines or electric motors, while racing karts use small 2-stroke or 4 -stroke engines,
Electric go-karts, low maintenance, requiring only that the lead-acid batteries of the cars be plugged into an array of chargers after each run, Since they, pollution-free, emit no smoke, Chicago Bears jersey, the racetracks can be indoors in controlled environments, A fully charged electric kart can run a maximum of 20 minutes be, e per, mance is affected,
4-stroke engines can be st, ard air-cooled industrial based engines, sometimes with small modifiions, developing from about 5 to 20 hp, Briggs unfortunately, austin collie colts jerseys are big business. it is estimated that tens of millions of dollars are lost each year to counterfeiters . amp; Stratton, Tecumseh, Kohler, Robin,, Honda, manufacturers of such engines, They, adequate, racing, fun kart appliions, There, also more powerful four-stroke engines available from manufacturers like Yamaha, TKM, Bil, or Aixro Wankel engine) offering from 15 hp up to 48 hp, They run to, around 11,000 rpm,,, manufactured specifically, karting, Those, used in some National Championship classes like the two-strokes,
2 -stroke kart engines, developed, built by dedied manufacturers, Comer, Jack Youngblood jersey, IAME Parilla, Komet), TM, Vortex, Titan, REFO, Yamaha, Rotax, manufacturers of such engines, These can develop from about 8 hp, a single-cylinder 60 cc unit MiniROK by Vortex) to 90 hp, a twin 250 cc, Today, the most popular egories worldwide, those using the Touch-,-go TAG) 125 cc units, The recent 125 cc KF1 engines, electronically limited at 16,000 rpm, Most, authentic Jets jerseys, water-cooled today; however, previously air-cooled engines dominated the sport,
Transmission
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, slide or lift off the ground completely,
Power is transmitted from the engine to the rear axle by way of a chain some rentals use a belt), Both engine, axle sprockets, removable; their ratio has to be adapted according to track configuration in order to get the most from the engine,
In the early days, karts were direct drive only, but the inconvenience of that setup soon led to the centrifugal clutch, the club level classes, Dry centrifugal clutches, now used in many egories Rotax Max is one example), have become the norm as the top international classes have switched to 125, cc clutched engines as of January 2007,
Tires < br />
Wheels, tires, much smaller than those used on a normal car, Rims, made of magnesium alloy or aluminum, Tires can support cornering, ces in excess of 2 G 20 m / s), depending on chassis , engine,, motor setup,
Similar to other motorsports, kart tires have different types, use appropriate to track conditions:
Slicks,, dry weather, In international level racing these, some of the softest, most advanced tires in motorsport, Some car tire manufacturers, such as Bridgestone, Dunlop or Maxxis, make tires, karts, There, also specific kart tire manufacturers, which include MG, MOJO,, Vega, Slick kart tires come in many different compounds, from very soft maximum grip) to very hard amusement, rental karts, less grip but long life span),
Rain tires, or “wets”,, wet weather, They , grooved, made of soft compound,,, narrower than slicks, Not all racing classes allow rain tires,
Special, such as spiked tires, icy conditions, or “cuts”, high grip dirt / clay speedways, Cuts, slicks modified with a lathe to optimize h, ling,
Data acquisition
As in other motor sports, several data acquisition systems have been developed, kart racing, These systems allow the driver to monitor from a display fixed on the steering wheel some parameters such as RPM, timing of laps including sectors), number of laps, best lap, cooling system temperature,, sometime speed or even gear, Charles Woodson youth jersey , shifter karts,
Some of those systems, able to record logging) laps data from the sensors, allowing replay of an entire running session or /, direct download to a personal computer equipped with a data analysis softw ,, More sophistied systems allow, more in, mation such as lateral, longitudinal acceleration or G-, ce), throttle position, steering wheel position, brake pressure,
External controls
Go-karts used in amusement parks can be fitted with additional electronic controls such as remote speed limiters to help promote a safer operating environment, In the event of an accident or an out of control racer, the track attendant can remotely slow or stop all vehicles on the track via radio control, 49ers Anthony Davis jersey, This remote speed control can also be used to limit, ng riders to a slow operating speed, while a race consisting only of adults is permitted a higher speed, These controls can be applied to both electric, combustion-engine karts,
Racing
Sprint race at Granja Viana, Brazil
Kart racing is generally accepted as the most economic, m of motorsport available, As a free-time activity, it can be per, med by almost anybody,, as a motorsport in itself, it is one of the sports regulated by FIA under the name of CIK), permitting licensed racing , anyone from the age of 8 onward,
In the USA, there is not as much FIA involvement; instead, many organizations regulate racing, such as the IKF International Kart Federation), MICHAEL OHER jersey, WKA World Karting Association), KART Karters of America Racing Triad),, the more recent Stars of Karting presented by the Indy Racing League,
In the UK, the MSA Motor Sports Association) regulate Karting, Some associations , such as NatSKA National Schools Karting Association), organize race meetings throughout the country under the authority of the MSA,
In Australia, kart racing is administrated by the Australian Karting Association on the behalf of FIA, CAMS ,
A variety of kart circuits permit the sport to be practiced, although only homologated tracks can have official races in Europe see Kart circuits),
Racing classes start at age 7 or 8 5 in the US with “Kid Karts”), generally run in 3-year age groupings or weight divisions until enior status is reached at age 15 or 16, depending on the series,
Racing, mats
Typically, race, mats, one of the following:
Sprint
Sprint racing takes place on dedied kart circuits resembling small road courses, with left, right turns, Tracks range from 1/4 mile 400 metres) to over 1 mile 1,600 metres) in length,
The sprint, mat is a series of short-duration races, normally, a small number of laps, that qualify, a final, with a variety of point scoring calculations to determine the event overall winner, Typical duration does not normally exceed 15 minutes, Here, speed, successful passing is of the most importance, It normally occurs in the, mat of three qualifying heats, a final race, trophy positions,
The FIA ??championships, including the Karting World Championship, take place in this, mat,
Endurance < br />
Pack of Laydown Enduros at tona, USA
Endurance races last, an extended period, from 30 minutes up to 24 hours or more,, one or more drivers, In general, consistency, reliability,, pit strategy is of greater importance than all out speed,
Called “Enduro” racing in the USA, most WKA
