Collin Veijer was born in Meppel, the Netherlands, on February 19th, 2005. He started his racing career by winning the Italian CIV MiniGP50 Championship in 2017.

After two more seasons in the CIV Italian Championship, Veijer was selected for the Red Bull Rookies Cup in 2020, finishing inside the Top 10 overall. In 2021, the Dutch rider completed a solid campaign with a KTM in the FIM CEV Moto3 Junior World Championship, as well as finishing in the points in 10 races in the Rookies Cup.

In 2022, Veijer fought for the title in the Red Bull Rookies Cup with José Antonio Rueda, only losing out in the final race of the season in Valencia. He took three wins and two third places, as well as finishing all fourteen rounds in the points. That same year, in the revamped FIM JuniorGP World Championship, Veijer took his first wins in the class, as well as three pole positions and a second position. He concluded the campaign sixth despite missing the first round due to injury.

At the beginning of 2023, Veijer was confirmed as a full-time Moto3 World Championship rider. At the Austrian GP, he became the first Dutch rider to claim a Grand Prix pole since Jurgen van der Goorbergh in 1999. He went on to get his first podium in Thailand and his first victory a few days later in Malaysia, which made him the first Dutch race winner in 33 years. Finally, he was seventh in the overall standings and the second best rookie of the season.

In 2024, he further established himself in the World Championship, concluding the campaign third. Along the way, he took one pole position, one victory, four second positions and other four thirds. Across 39 races in Moto3, he claimed 2 victories, 11 podiums and 3 pole positions.

2025 is a new and exciting challenge for Veijer, as after two years in Moto3, he moves up to the Moto2 class to partner with Deniz Öncü.
