The 2006 MotoGP champion, Nicky Hayden has died from injuries sustained when he was hit by a car while cycling in Italy last Wednesday.
Hayden was riding near Rimini when the accident occurred.
He was subsequently rushed to a local hospital with severe head and chest trauma and several fractures, before being transferred to the Bufalini Hospital in Cesena.
The 35-year-old’s condition was not stable enough to perform surgery to relieve the pressure on his skull caused by cerebral edema.
He remained in a critical condition in intensive care through the weekend.
A statement from the hospital said Hayden died on Monday afternoon.
Hayden made 217 MotoGP starts between 2003 and ’16, beating Valentino Rossi to the 2006 world championship in the fourth of his six seasons with the factory Honda team.
He moved to Ducati in 2009 and spent his final two full-time seasons with the Aspar Honda team before switching to the World Superbike Championship with the Japanese firm last year.
The American made two more MotoGP starts in 2016, as an injury replacement for Marc VDS Honda’s Jack Miller at Aragon and at Phillip Island for factory Honda rider Dani Pedrosa.
Hayden was 13th in the 2017 World SBK standings after five rounds, failing to finish the first race at Imola the weekend before his accident and crossing the line 12th in the other.
