The 2025 FIA Karting World Championship for the OK and OK-Junior categories took place from 11th to 14th September at the historic Åsum Ring in Kristianstad, Sweden. As always at this level, the sporting intensity was at its peak, with a world title awarded on a single event, in an atmosphere combining suspense and twists and turns. The unpredictable weather on the south-east coast of Sweden did nothing to make things easier for the 217 drivers taking part (109 in OK-Junior, 108 in OK), adding an element of uncertainty to the competition.
