A popular category that includes a wide range of drivers, from the youngest to the most experienced, KZ2, the second division of 125cc gearbox karts, was attended by nearly 90 participants at Varennes sur Allier (FR) for its most important meeting of the season, the International Super Cup, the successor to the 2012 World Cup.

During an intense and eventful event, representatives of 18 nationalities competed ruthlessly on a spectacular track. The French driver Alexandre Arrue (Praga-Parilla-B'Stone) was the first leader, taking pole position in a qualifying disturbed by a rain shower ahead of two of his compatriots, Paul David (Tony Kart-Modena-B 'Stone) and Thomas Laurent (Tony Kart-Vortex-B'Stone). The German Riccardo Negro (DR-TM-B'Stone) regained the lead at the end of the six heats that each driver had to race in by beating the New Zealander Daniel Bray (GP-TM-B'Stone) and the Italian expert Marco Zanchetta (Maranello-TM-B'Stone). The qualification phase ended with the two prefinals where only the top 17 would be chosen for the title race.

Regularly in the leading group from the start of the weekend, the young French driver Dorian Boccolacci (Energy-TM-B'Stone) was ahead in prefinal-1 against the Italian Simone Brenna (TB Kart-Modena-B 'Stone), while Riccardo Negro finished third and Marco Zanchetta retired after a collision. Daniel Bray won prefinal-2 followed by the Czech Jan Midrla (Birel-TM-B'Stone) and Alexandre Arrue, recovered from concerns encountered in the heats. Everything was in place for the final.

Daniel Bray led for three quarters of the race while Dorian Boccolacci and Riccardo Negro shared second place, but the situation changed quickly near the end.

After moving up 10 places, the Italian Loris Spinelli (CRG-TM-B'Stone) took the lead with four laps to go, but Dorian Boccolacci managed to outflank him and brilliantly won the International Super Cup. Spinelli, who finished second to Arrue and Bray, was penalized and immediately appealed, which suspended the standings behind the winner.
