Kay de Wolf

In 2017, he finished seventh overall in the 85cc class in the FIM Motocross Junior World Championship. de Wolf was able to finish second in the 85cc class in both the 2018 and World Championship in 2018. A crash in the first race meant that de Wolf's second race win was not enough for the title in the European Championship, whilst a 2–6 scorecard placed him in the runner-up spot in the World Championship.[4]

On the back of his results aboard an 85, de Wolf was signed by Husqvarna Motorcycles to compete aboard a 125 in the 2019 European Motocross Championship.[5] de Wolf would immediately show his sand riding skills by placing second in race two at round one of the series. His first overall podium would come at the second round of the series, with sixth overall being his final championship position. Being more of a sand specialist, the hardpack terrain in Italy for that year's Junior World Championship would see him finish thirteenth overall in the 125 class. Domestically, de Wolf won his first Dutch Masters of Motocross title in the 125 class.

Continuing his rapid rise up the ranks, de Wolf moved up to the EMX250 class in 2020. He again proved himself to be able to adapt to the new class quickly, finishing fourth in the final standings and picking up two overall podiums.

After these results across the European Championships, de Wolf joined Husqvarna's factory team in the MX2 class of the 2021 FIM Motocross World Championship. de Wolf was immediately a top-ten finisher on debut and by round four recorded his first pole position, race top-three and overall podium at Oss. Two rounds later, once again in sandy conditions in Lommel, de Wolf recorded his second pole position. This was followed up by a third place in race one and taking a start-to-finish victory in race two, for second overall.[6] The rest of the season saw de Wolf finish consistently in the top-10 and pick up two more podiums on the way to seventh in the final standings.

de Wolf repeated his race win at Lommel the following year. Once again it was good enough for second overall at that Grand Prix, which was accompanied by 3 other podiums across the season. He missed three Grand Prix due to a hand injury sustained from being hit by a motorist whilst cycling.[7] Sixth in the final MX2 standings was followed by his debut for Netherlands at the 2022 Motocross des Nations. He went on to win his first Grand Prix overall during the 2023 season in Latvia, winning both races in the process. This allowed him to become the leader of the World Championship for this first time in his career.[8] This lead would only last one round however, with an ankle injury sustained in a training crash meaning that he lost the lead at the following round. He continued to race with the injury due to his championship position, but a heavy fall in training leading up to the Belgian round caused him to miss the following four rounds and drop out of contention. de Wolf returned for the final two rounds of the season, wrapping up sixth in the final standings and competing in the 2023 Motocross des Nations. Domestically, de Wolf became Dutch Masters of Motocross champion in the 250 class.
