A 16-year-old Iker Lecuona debuted in the Moto2™ World Championship at the minimum age for the catgeory. Born in 2000, Lecuona raced in the FIM CEV Repsol International Championship in Moto2™ in 2015 and 2016, with a slew of impressive top five results. His debut in the Moto2™ World Championship saw the Spaniard race for the Garage Plus Interwetten team to replace Dominique Aegerter, and Lecuona remained with the team for 2017 on Kalex machinery. He stayed with the team for 2018 as they switched to KTM machinery, with Lecuona securing his first Grand Prix podium at the season finale in Valencia.

Lecuona remained with the same team for 2019 and picked up a rostrum finish at the Thai GP, and even debuted in the premier class for the season finale in Valencia. 2020 saw him become a full-time Tech 3 rider and he impressed without sparkling in his rookie year, securing three Top 10 finishes. More top 10 finishes came in 2021, as Lecuona then moved across to WorldSBK to join the factory Team HRC effort. At the 2023 Spanish GP, Lecuona was back on the Grand Prix grid replacing injured Marc Marquez at Repsol Honda.
