Lorenzo Dalla Porta made his World Championship debut in 2015 as a replacement for Isaac Viñales in the Husqvarana Factory Laglisse team. The opportunity arose as he had raced for the Laglisse outfit in the FIM CEV Repsol Moto3™ Junior World Championship, and he split his time between the two series. In the CEV he took ninth in the championship, including a third place finish at Jerez. His adaption to the World Championship was rapid and he twice scored points, first with a stand out eighth in Silverstone and then again with 11th in Misano. Dalla Porta then won the FIM CEV Repsol Moto3™ Junior World Championship in 2016, as well as appearing on the world stage once again in a number of Grands Prix – replacing Philipp Oetll in Mugello, Jorge Navarro in Assen and then Romano Fenati from Silverstone on. For 2017, the Italian raced with the Pull&Bear Aspar Mahindra Team. After a more difficult year, 2018 saw him switch to Leopard Racing and take his first podiums, as well as a first race win. Remaining with the team for the following season, 2019 is a year Dalla Porta will never forget. Four wins, six P2s and one P3 saw the Italian crowned as the 2019 Moto3™ World Champion. After a sensational season, Dalla Porta made the step up to the intermediate class with Italtrans Racing Team for 2020. It proved a year of adaptation for Dalla Porta though, managing to crack the points just twice while 2021 was another year of learning for the Italian. 2022 saw some slight improvements, scoring seven point scoring finishes, and it was enough to convince Pertamina Mandalika SAG Team to hand him a chance for 2023.
