Following this, he received backing in 2009 from the Dutch Beursfoon team, initially on a KTM before switching to Suzuki, mainly competing in the MX2 class of the 2009 FIM Motocross World Championship.
[9] The 2011 FIM Motocross World Championship season saw Butrón return to riding a KTM, this time for the Italian Silver Action team.
Being a consistent feature at the front, he picked up three overall podiums across the opening six rounds, before winning the second MX2 race in Brazil and in doing so being the first rider to beat Jeffrey Herlings in 2013.
Following these achievements, he made his fourth appearance for Spain at the Motocross des Nations in 2013, recording the team's highest individual finish in the main races.
[14] Once again selected for Spain at the Motocross des Nations, the team was not able to qualify for the main races, with Butrón moving up to a 450 to ride in the MXGP class and finishing second in the B-Final individually.
Due to the under-23 age rule, Butrón had to move the MXGP class for the 2015 FIM Motocross World Championship, finding a home at the Marchetti Racing KTM Team.
At that season's Motocross des Nations in France, Butrón formed part of the Spanish team that finished eleventh in the final standings.
Again renewing with the Marchetti team, Butrón slipped further down the MXGP rankings in the 2017 FIM Motocross World Championship, a single tenth place being the high point on his way to nineteenth in the final standings after missing four rounds from injury.
Butrón competed in six MXGP rounds as a wildcard in 2021 and focussed fulltime on the Czech Motocross Championship for his JD Gunnex team, winning the MX1 title by fifty points from his closest rival.
[22] In addition, he was involved in a close three-way battle for the Elite-MX1 title in Spain, eventually finishing third behind Carlos Campano and Ander Valentín.
[24] After four years of missing out, Butrón was able to reclaim the Elite-MX1 crown within the Spanish Motocross Championship, after a season-long battle with rival Carlos Campano.
The JD Gunnex team closed ahead of the 2023 season, leaving Butrón initially with his sole focus being on the 2023 Spanish Motocross Championship.
[25] Following this, he took his career to the United States for the first time, joining his former JD Gunnex teammate Lorenzo Locurcio in the Wildcat Race Team to compete in the 2023 AMA National Motocross Championship.
