The first competition of the 2021 season, the WSK Champions Cup allowed Birel ART Racing to debut it's team on the Adria Karting Raceway in the presence of a record number of participants. In Mini, the largest category, Van Langendonk did very well to reach 6th position in the Final. Spirgel showed excellent competitiveness in the Junior class, and Kucharczyk adapted perfectly to the OK category, as did Thanapongpan in KZ2.

In Sarno, the last event of the WSK Super Master Series confirmed the high level of performance of several drivers of the Birel ART Racing Team. Kremers' 4th place overall in the KZ2 series allowed him to calmly contemplate the rest of the international season, while the potential was there in OK with Coluccio and in OK-Junior with Camara.

In the wake of the Winter Cup, the performances of the Birel Art Racing drivers were at their peak at the first KZ2 meeting of the WSK Super Master Series at the Lonato circuit. The results have improved compared to the previous week as Kremers mounted the Final podium while Irlando was in the top five and Dahlberg reached the top ten. Coluccio was also very competitive in OK.

The resumption of racing was not easy for the drivers from the Birel ART Racing Team during the first meeting of the WSK Super Master Series at the Adria Karting Raceway. As demonstrated by the great victory from Rafael Camara in OK-Junior, the team worked well during the winter and the equipment is already very competitive.
