250 Career
After being part of the Troy Lee Designs Red Bull KTM amateur team for a few years, Brown made his professional debut for the team at the Florida round of the 2019 AMA National Motocross Championship. After finishing twelfth overall, which included a tenth place in the second race, Brown made his full-time debut with the team during the COVID-19 pandemic-impacted 2020 season. He missed the opening two rounds of the 250SX East class of the 2020 AMA Supercross Championship due to injuring a nerve underneath his shoulder blade. After making his supercross debut at the third round in Atlanta, Brown was able to record four top-six finishes, with a best of fourth place at two events to finish ninth in the final standings. At the fifth round of the 2020 AMA National Motocross Championship, Brown sustained a knee injury which left him ending his first full season on the side-lines.
For the 2021 season, Brown's Troy Lee Designs team became the official Gas Gas team in American racing. Switching to the 250SX West class, Brown secured his first professional podium by finishing third at the second round of the 2021 AMA Supercross Championship at Daytona. He missed the next three rounds due to a broken hand and eventually finished twelfth in the final standings. Brown's best result in the 2021 AMA National Motocross Championship was fifth overall at the seventh round at Washougal. At the following round he broke his collarbone and suffered concussion which ended his race season. The 2022 AMA Supercross Championship would see Brown visit the podium three times in the 250SX East class and finish the season in third in the final standings. As part of this, he led a professional supercross race for the first time when he was at the head of the field at the Foxborough round for fourteen laps. He stayed injury free and completed a full season of the AMA Motocross Championship in 2022, scoring four top-ten overall results to finish tenth in the final standings.
Brown missed the last two rounds of the 2023 AMA Supercross Championship due to a hand injury and finished the 250SX West class eighth in the final standings. Due to this, he missed all but the last five rounds of the 2023 AMA National Motocross Championship, where he had two tenth overall finished on his return. Brown was consistent in the 250SX East class of the 2024 AMA Supercross Championship, finishing in the top five in each of the first six rounds. He would eventually finish the season in fourth, one point away from third in the final standings. Brown was also consistent throughout the 2024 AMA National Motocross Championship, with three top-six overall finishes resulting in eighth in the final standings of the 250 class. At the season ending 2024 SuperMotocross World Championship final rounds, Brown was able to take his first professional victory at the last event in Las Vegas. This victory was enough for him to finish third in the final standings of the 250SMX class.
At the end of the 2024 season, it was announced that Brown would be leaving the Troy Lee Designs team for the first time in his professional career and joining the Monster Energy Yamaha Star Racing team for 2025. Making his debut for the team in the 250SX East class of the 2025 AMA Supercross Championship, Brown was leading the main event at the opening round in Tampa before crashing out. The crash left him with broken vertebra requiring surgery, ruling him out for the rest of the championship. Brown was able to come back for the ninth round of the 2025 AMA National Motocross Championship. In the opening race he crashed and sustained a concussion, ending his 2025 season altogether.
Brown started the 2026 AMA Supercross Championship in the 250SX East class, where at the opening round in Arlington, Texas, he was able to take his first professional supercross victory. He followed this up with a third place at the second round, before a crash at the fourth round caused a broken wrist and dislocated shoulder, ending his campaign.
