Jaume Masia hails from Valencia in Spain and after starting racing at the age of six, he quickly ascended through the ranks to win the Spanish 140cc Championship just three years later, alongside the Valencian 150cc title. He would continue this promising form in road racing to claim sixth in the Spanish PreMoto3 Championship in his debut year of 2013 before landing a ride in the Red Bull MotoGP Rookies Cup for the following season. After a year in the Moto3™ Junior World Championship in 2016 with the Junior Team Estrella Galicia 0,0, Masia moved to the Valencian-run Cuna de Campeones outfit for the following season and was quick immediately, eventually claiming two victories in Aragon and Valencia at the end of the year. Mid-way through the season, Masia was called up to replace the injured Darryn Binder at the Austrian Grand Prix; showing himself to be a quick learner, he finished ninth on his World Championship debut and was signed immediately for a full-time ride in 2018. He was crowned Rookie of the Year at the Bester Capital Dubai squad and he remained with them for 2019, a year in which he earned a first race win in Argentina, as well as two third place finishes. 2020 saw him make the move to Leopard Racing and an impressive campaign was capped with back to back victories in the Aragon double as he finished sixth in the Championship. 2021 saw a return to KTM machinery with Aki Ajo’s squad, and despite claiming an opening day victory, his sole win of the year, a Championship bid never truly materialized for the number 5 as he was outshone by rookie teammate and eventual title victor Pedro Acosta. In 2022, Masia celebrated two triumphs and achieved podium finishes six times, ultimately concluding the season in a commendable sixth place in the standings. A fresh chapter awaited him in 2023 as he joined Leopard Racing, where he solidified his status as a legitimate title contender. Notably, he secured his inaugural victory at Assen, followed by additional wins in India, Japan, and Qatar, ultimately claiming the prestigious title of world champion. Looking ahead to 2024, Masia made the transition to Moto2™, joining the Pertamina Mandalika SAG Team.
