Jorge Martin joined the Red Bull Rookies Cup for the 2012 season. Unfortunately it was a season plagued by various injuries, but the following year he tried again and finished runner-up behind the 2013 champion Karel Hanika. In 2014 he dominated the same Championship and took the crown. For 2015 Martín took the next step and participated in his first full season in the Moto3™ World Championship, where he joined the Mahindra Mapfre Aspar team. An awesome seventh in Aragon helped the Spaniard to finish the year 17th overall, with he and the Aspar team electing to continue their relationship for 2016. For 2017, the Spaniard moved to Del Conca Gresini Racing Moto3 to replace outgoing title contender Enea Bastianini.
The master of qualifying and on pole for half the entire season, Martin took an impressive nine podiums despite a mid-season injury, and his maiden win in the season finale on the way to P4 overall. His stellar year would arrive in 2018 as Martin beat Marco Bezzecchi to the Moto3™ crown, claiming seven victories despite picking up another mid-season injury. Red Bull KTM Ajo in Moto2™ became the Spaniards home in 2019, and he rewarded his new team with podium finishes in Japan and Austria toward the tail end of the season. A title charge awaited in 2020, a Spanish GP podium followed up with a victory and podium finish in the Spielberg double, he was right in the Championship mix. However, a positive Covid-19 test meant he missed the Misano double, and successive retirements put to bed any plans of the Championship. There were three more podiums in the final five Grand Prix, including victory in Valencia, which helped him secure fifth place in the standings. 2021 sees him make the jump up to Pramac Racing in MotoGP™.
