'''Original Kart''' ('''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 [[List of FIA championships|FIA championships]].

The class was originally called '''Intercontinental A''' ('''ICA'''), first introduced in 1981 at the [[Karting European Championship|European Championship]] as a secondary direct-drive class to [[KF1|Formula K]]. The class was first contested at the [[Karting World Championship|World Cup]] in 2006. In 2007—after 26 seasons of racing—ICA was replaced by '''KF2''' and became the primary class in 2010, replacing [[KF1]] at the [[Karting World Championship|World Championship]]. The KF2 class was renamed to '''KF''' upon the demise of KF1 in 2013, and was replaced by OK regulations in 2016.

OK is contested as the primary direct-drive class at the [[Karting World Championship]] and the [[Karting European Championship]].

== History ==

=== Intercontinental A (1981–2006) ===

In 1981, Intercontinental A (ICA) was introduced alongside [[Formula K]] as a secondary [[direct-drive]] class for the [[Karting European Championship|European Championship]].

[[Stefano Modena]] completed back-to-back [[Karting European Championship#Secondary direct-drive classes (1982–2009)|ICA European Championship]]s in 1984, a feat that would not be repeated until [[Andrea Kimi Antonelli]] under OK regulations in 2021.

The [[Karting World Championship|ICA World Cup]] was introduced in 2006, the final year of ICA regulations, won by French driver Mike Courquin.

=== KF2/KF (2007–2015) ===

In January 2007, the [[CIK-FIA]] decided to replace the 100&nbsp;cc water-cooled [[Two-stroke engine|two-stroke]] ICA engines with 125&nbsp;cc Touch-and-Go (TaG) water-cooled two-stroke KF2 engines, producing {{cvt|34|-|36|hp|kW}}. Now the secondary class to [[KF1]]—which had replaced [[KF1|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&nbsp;kg and 158&nbsp;kg for national and international events, respectively. KF2 karts were equipped with an electric starter and a [[centrifugal clutch]]. The engine was [[rev limiter|limited]] to 15,000&nbsp;[[Revolutions per minute|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.<ref>{{Cite news |title=KartCafe News - CIK-FIA World Karting Championship For Drivers Zuera (ESP) - 16-19.09.2010 |url=http://www.kartcafe.it/content.php/157-CIK-FIA-World-Karting-Championship-For-Drivers-Zuera-(ESP)-16-19.09.2010?s=f6dc26c7318961e77adbbb4bc927145b&commentid=144579 |archive-url=https://web.archive.org/web/20110722040403/http://www.kartcafe.it/content.php/157-CIK-FIA-World-Karting-Championship-For-Drivers-Zuera-(ESP)-16-19.09.2010?s=f6dc26c7318961e77adbbb4bc927145b&commentid=144579 |archive-date=2011-07-22 |access-date=2025-09-03 |work=KartCafe - Karting MotorSport |language=it}}</ref> 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 the end of KF1 regulations, KF2 became known as simply KF and returned to the World Championship as the primary class once more.

=== Original Kart (2016–present) ===

In 2016, Original Kart (OK) regulations replaced KF in the direct-drive category, after its perceived failure within the kart racing community and restrictive regulations resulted in reduced entries at international competitions.<ref>{{Cite web|url=https://www.fia.com/es/news/official-presentation-new-2016-engines-pf-intl|website=FIA|date=16 June 2015|access-date=20 September 2024 |title=Official presentation of the new 2016 engines at PF Intl }}</ref> OK karts had much of the electronics removed, and had to be push-started.

== Specification ==

=== Original Kart (OK) ===

There are eight main technical features of the OK regulations:<ref>{{Cite web|url=https://www.fiakarting.com/page/fia-karting-categories|title=FIA Karting - Categories|access-date=21 September 2024}}</ref>

* 125&nbsp;cc direct-coupled, water-cooled [[two-stroke]], mixed-lubrication engine.

* Valve inlet in the piston skirt. 

* Screw [[carburettor]] with a maximum diameter of 24&nbsp;mm.

* Maximum speed ([[rev limiter|limiter]]) of 16,000&nbsp;[[Revolutions per minute|rpm]]. 

* Power valve at the exhaust.

* Single rear brake with hydraulic control. 

* Premium tyres, medium gum [[Glossary of motorsport terms#T|compound]].

* Minimum weight 150&nbsp;kg, driver included.

Engines, chassis, bodywork, brakes and tyres are subject to the homologation system put in place by the CIK-FIA. Each year, the tyres and the fuel for each category, as well as the KZ and KZ2 carburettor, are chosen after a call for tenders.
