KZ (karting)

KZ1 is a kart racing class using 125 cc water-cooled two-stroke engines yielding approximately 46–50 hp (34–37 kW), 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. Both engines and chassis must be approved by the CIK-FIA racing governing commission. It is open to top drivers aged 15 and over. Minimum weight is 170 kg (370 lb), this includes the kart and driver. They can accelerate from 0-100 km/h in 3 seconds. KZ1 has a top speed of 180 km/h (110 mph).

This class used to be called Formula C. It was discontinued in favor of Super ICC and renamed KZ1 by the CIK-FIA in January 2007.

There is a European KZ1 Championship and a World Cup, both organized under CIK-FIA.
