two-stroke engines with 125 cc Touch-and-Go (TaG) water-cooled two-stroke engines (KF type).The engines produce . The chassis and engines must be approved by the CIK-FIA. Minimum weight is 145 kg, including kart and driver.
Karts are equipped with an electric starter and clutch. The engine
rpm is limited to 14,000 rpm.
It is one of the highest kart classes with national championships (perhaps with different tyre rules).
There is a European championship, a World Cup, as well as Oceania and Asia-Pacific championships. The
Junior Monaco Kart Cup is taking place each year in this format.
For 2013 the class was renamed KF-Junior.
In 2016, the karts were completely re-designed by removing much of the electronics. The karts are now push started. The class was subsequently renamed OK-Junior, standing for Original Kart.
