Spanish rider Luis Salom has died from injuries sustained in second practice ahead of this weekend's Moto2 race at Circuit de Barcelona-Catalunya, the championship has confirmed.
24-year-old Salom – a veteran of the international scene who had competed in both Moto3 and Moto2 – crashed his Kalex machine during the session on Friday afternoon. He was immediately attended by medical staff and taken to the nearby Hospital General de Catalunya.
He underwent surgery on arrival, but succumbed to his injuries at 16:55 local time.
Salom made his World Championship debut in 2009, earning nine victories and 10 further podiums in the Moto3 category and finishing third in the standings in 2013.
He stepped up to Moto2 in 2014 and scored a brace of second-place finishes, the most recent coming at the opening round of this season in Qatar.
Salom is the first rider to be killed at a World Championship event since Marco Simoncelli, who died from injuries sustained during the 2011 Malaysian round of the premier MotoGP category.
