Roan van de Moosdijk

van de Moosdijk competed internationally during his junior career. In 2013, he was able to finish tenth overall in the EMX85 class of the European Motocross Championship. That season he also competed for the first time in the FIM Motocross Junior World Championship. In 2014, van de Moosdijk was one of the leading 85cc riders in Europe. At the European Championship, he was able to secure pole position in the class before finishing second overall behind Jago Geerts. At that season's Junior World Championship, he finished eleventh overall after recording the fastest time in his qualifying group.

He moved up to the EMX125 class for 2015, competing as a privateer with a best race finish of eleventh. This was backed up by two points scoring finishes at the Junior World Championship. These performances were enough for him to be signed by DP19 Yamaha team for 2016.[5] van de Moosdijk was able to finish third overall at the opening round and would have a final championship finish of fifth. The 2016 Junior World Championship was held in Russia and van de Moosdijk distinguished himself by finishing second overall, after picking pole position along with the win in the opening race.

van de Moosdijk moved up to the EMX250 class during the 2017 European Motocross Championship, but could only compete in three rounds due to injury. In addition to these three rounds, he made his Grand Prix debut, riding in the Czech and Belgian rounds of the 2017 FIM Motocross World Championship in the MX2 class. He was retained by the same team for the 2018 season and was able to be a consistent figure at the front of the field.[6] He picked up his first class overall podium at the sixth round, before following that up with his first overall win in Ottobiano a week later.[7] Two more podiums followed this enabling him to finish third in the final championship standings.

2019 saw van de Moosdijk move both teams and manufacturers, stepping across to the F&H Kawasaki team. This would see him come away with the EMX250 title, picking up six race wins and three overall victories along the way. Despite this, it was a closely fought championship battle, with van de Moosdijk prevailing by six points over Stephen Rubini who was himself five points ahead of Alberto Forato. On the back of this, he had three notable performances as a wildcard in the MX2 class of the 2019 FIM Motocross World Championship. At the Turkish round, a third place in race two was enough for an overall podium.[8]

Staying with the same team, van de Moosdijk made his full-time world championship-level debut in 2020. By the third round, he was able to finish on the podium, picking up second overall in Latvia. He picked up a further four overall podiums throughout the season, as well as his first World Championship-level race win in race two at the third Lommel round, on his way to seventh in the final standings.[9] Remaining with F&H Kawasaki for the 2021 FIM Motocross World Championship, van de Moosdijk picked up a handful of third-place race finishes at the start of the season, before a broken scaphoid derailed his campaign.[10] Despite this he did return to compete for his country at the 2021 Motocross des Nations, helping them finish second overall.

van de Moosdijk was signed up on a two-year deal by the Rockstar Energy Husqvarna team, starting in the 2022 FIM Motocross World Championship.[11] A shoulder injury sustained at the second round of the season saw him miss all but the final five Grand Prix, of which he was able to pick up one overall podium.[12] The 2023 FIM Motocross World Championship would be van de Moosdijk's final season in the MX2 category due to the under-23 rule. He had a strong start to the season, culminating in winning the opening race at the third round in Switzerland. This was only his second world championship-level race win and his first since the 2020 season. He was able to take two overall podiums in Portugal and Latvia, before winning the Saturday qualifying race in Germany. A broken collarbone at the Czech round meant that he missed the following three rounds and would eventually finish eighth overall in the championship standings. Domestically, he finished his final season on a 250 by finishing runner-up in the 2023 Dutch Masters of Motocross series behind teammate Kay de Wolf.
