The Catalonia MotoGP in Barcelona was overshadowed by a series of frightening high-speed crashes that left multiple riders injured and forced race officials to halt the event twice before Fabio Di Giannantonio eventually secured victory.
The most serious incident involved Spanish rider Alex Marquez, who suffered a fractured neck vertebra and a broken collarbone after colliding with Pedro Acosta during the race.
According to race reports, Acosta had been leading on lap 12 when his KTM machine suddenly lost power on a straight section of the circuit. The Spaniard reportedly attempted to warn riders behind him as he slowed abruptly, but Marquez had little time to react.
The Gresini Ducati rider slammed into the rear of Acosta’s bike at high speed before both rider and machine were violently thrown toward the barriers. Television footage showed Marquez cartwheeling through the air in one of the heaviest crashes of the MotoGP season so far.
Medical teams quickly attended to the Spaniard before he was transported from the circuit by ambulance. His team later confirmed that he remained conscious following the incident.
Further examinations revealed what Gresini Racing described as a “marginal fracture of the C7 vertebra,” located at the base of the neck, alongside a fractured right clavicle. The collarbone injury was expected to require surgery, with stabilisation using a metal plate.
In a social media update posted later in the evening, Marquez attempted to reassure fans despite the severity of the crash.
“Everything under control,” the rider wrote. “Time to go into the operating room tonight, but I couldn’t be in better hands.”
He also thanked supporters for the flood of messages he received after the accident.
The dramatic collision triggered the first red flag of the afternoon, forcing organisers to suspend the race while debris and damaged safety barriers were cleared from the circuit.
When racing eventually resumed, the chaos continued.
French rider Johann Zarco crashed heavily during the restart, prompting officials to stop the race for a second time. Zarco reportedly became entangled with his motorcycle during the fall.
His LCR Honda team later confirmed multiple injuries, including damage to both the anterior and posterior cruciate ligaments, as well as injury to the medial meniscus. Doctors also reportedly identified a small tear to the fibula area near the ankle.
The Frenchman remained under medical observation overnight and was expected to return to France for specialist consultations regarding the next stage of his recovery.
The incidents reignited ongoing conversations around rider safety in MotoGP, particularly regarding the dangers posed by mechanical failures at extremely high speeds.
Modern MotoGP bikes can exceed 350 km/h on long straights, leaving riders with only fractions of a second to react when unexpected incidents occur ahead of them. Several former riders and analysts have previously warned about the increasing physical risks associated with modern racing technology and tighter pack racing.
Despite the disruptions and tension surrounding the event, the race eventually resumed for a third and final start.
Italian rider Fabio Di Giannantonio managed to keep his composure amid the chaos to claim victory for Ducati in Barcelona. He finished ahead of Joan Mir and rising Spanish talent Fermin Aldeguer.
Di Giannantonio himself was fortunate to avoid injury after being struck by debris during the Marquez incident. Speaking after the race, the Italian acknowledged the emotional impact the crashes had on the paddock.
“Today has not been an easy day for everybody. I really hope that Alex is fine,” he said.
“We’ve been really lucky. We know that our sport is amazing. We try to give an amazing show, but also we are humans and we are in danger.”
The Catalonia weekend had already been affected by injury concerns before Sunday’s race began. Reigning MotoGP world champion Marc Marquez, Alex’s older brother, was absent from the event after fracturing his foot during the previous race weekend in France.
His absence, combined with Alex Marquez’s injuries, marked a painful period for one of MotoGP’s most well-known racing families.
MotoGP officials have not yet announced whether any additional safety reviews or technical investigations will follow the incidents in Barcelona. Details surrounding the exact mechanical issue on Acosta’s KTM also remain unclear.
The crashes are likely to dominate discussion ahead of the next MotoGP round, as teams, riders and officials once again confront the balance between spectacle, speed and rider safety in one of the world’s most dangerous motorsports.
