Mini & Cadet: The First Rungs of the Ladder

Arvid Lindblad, Gabriel Bortoleto and Andrea Kimi Antonelli have one line in common on their CVs: Mini karting, and a climb from 60cc to Formula One in under seven years. The smallest karts in the sport have quietly become its most efficient talent factory — and, for scouts, by far its most closely watched grids.

Where it came from

Junior-entry karting grew up nationally, and each country built its own bottom rung. In Britain the ladder starts with Bambino for ages six to eight, then splits into the Cadet classes for eight- to thirteen-year-olds — Honda Cadet and IAME Cadet being the staples of the Super One paddock. Australia runs Cadet 9 and Cadet 12 on restricted Vortex Mini Rok and Comer power, delivering a deliberately gentle six to eight horsepower. But the class that would go global was born in Italy: the 60cc Mini category first appeared at the Torneo delle Industrie in 1984, and Italian Mini racing became the sport's deepest junior talent pool, with the big Lonato and WSK meetings drawing entries from every continent.

How it evolved

For decades the Mini and Cadet world was a patchwork of national rules. The turning point came in 2020, when the CIK-FIA formally recognised Mini and pulled the various national 60cc classes towards a single technical regulation. A younger tier, Mini U10, followed in 2023. Meanwhile the machinery quietly became serious: 2024 test data measured 60 Mini karts at 106–108km/h with cornering speeds higher than OK-Junior — quick enough that the FIA moved to regulate Mini lap times from 2026. The "kiddie class" now needs a speed limiter.

The alumni list explains the scrutiny. Max Verstappen, Charles Leclerc, Pierre Gasly and Esteban Ocon all came through the Mini ranks; today's Mini graduates are reaching Formula One faster than any generation before them. Scouts, managers and factory teams now treat 60 Mini as the real start of a professional career — driver-coach deals and factory contracts are routinely signed before a driver's eleventh birthday.

The class today

The modern pathway is now clear everywhere: Bambino teaches throttle and wheel, Cadet teaches racing, and Mini teaches winning under real pressure. Grids at the major Italian and WSK meetings are routinely the largest of any class on the bill, and national scenes — Honda Cadet in the UK, restricted Mini Rok in Australia, Micro and Mini MAX in the Rotax world — feed into the same international funnel.
