Barry Baltus competed in the 2018 and 2019 editions of the Red Bull Rookies Cup. In his second season, the Belgian finished third twice, in Aragon and Assen. At the same time, he joined the FIM CEV Repsol and achieved 4 Moto3™ podiums, including a victory at Estoril. Thanks to his good performances, the CarXpert Prüstel GP team gave him the opportunity to make the leap to the Moto3™ World Championship. Despite an overall performance that went largely unnoticed in terms of results, his performance was sufficient enough for the NTS RW Racing GP to trust him with a two-year Moto2 ™ deal ahead of the 2021 season. A year of learning took place for the young Belgian, adding his first Moto2™ points to his name in Germany with 14th. 2022 saw his development continue, with Baltus pulling off a string of fine performances, which saw him take point-scoring finishes on nine occasions. His development continued in 2023 with a career-best P6 at the British GP before remaining with RW Racing for 2024, which allowed the Belgian to start the season in style. Baltus finished a career-best second at the Qatar GP, and with further promising results, he would earn a spot on the 2025 grid after signing for Fantic Racing.
