Maria Herrera was the first female rider to win an FIM CEV race, as she took victory in the Moto3 class at Aragon in 2013. She went on to take another win in Navarra that year but lost out on the title fight due to injury.

That same year, she made her debut in the Grand Prix paddock at Aragon as a wildcard, and made three further appearances in the championship the following season. In 2015, she completed a full season in Moto3, scoring a best result of 11th in the Australian round at Phillip Island. 

After two more Moto3 campaigns, she made the move to the FIM Supersport 300 World Championship in 2018, riding a GYTR-kitted R3 bike. The Spaniard was a consistent front-runner and achieved fourth at the final round at Magny-Cours. 

In 2019, she stepped up to WorldSSP and scored four points finishes on the Yamaha R6, while she also impressed in the inaugural MotoE World Cup, scoring a best finish of fifth at Misano. In 2020, she contested both championships again, although only running a partial WorldSSP campaign, and took a best finish of seventh in the Magny-Cours round of MotoE. 

For 2021, the 24-year-old will race for the Biblion Motoxracing Yamaha WorldSSP Supported Team, with hopes of challenging for regular top 10 finishes.
