Arno Cazet is a young French motocross rider from Réunion Island, often described as one of the sport's rising stars. He started riding very early, around the age of 5, and quickly made a name for himself on sand tracks.

He distinguished himself by winning a round of the French Junior Sand Championship in Berck-sur-Mer in 2023 and was nicknamed the "Prince of the Sands" for his performances on this type of terrain.

In 2023, he also finished third in the French Junior 125cc Championship and won several rounds in major sand races for young riders. After moving to mainland France to further his development, he joined Team AG Motorsport for the 2024 season, with whom he competed in the French Junior Motocross Championship, the SX Tour, and some races in the European 125cc Championship.

Over the seasons, Arno has shown consistency in the rankings of the French Junior Championship, notably achieving top-10 finishes and podium places in some rounds, which has led him to be considered a promising figure in the next generation of French motocross.
