CESENA, Italy – Former MotoGP champion Nicky Hayden died on Monday as the result of injuries he suffered after being struck by a car while riding a bicycle in Italy on May 17.

He was only 35 years old. His fiancée Jackie, mother Rose and brother Tommy were at his side.

Hayden, from Owensboro, Ky., was struck by a car while training on his bicycle between Tavoleto and Riccione, south of the resort town of Rimini. He was taken by ambulance to a hospital near Rimini for treatment before being transferred to Maurizio Bufalini Hospital in Cesena, where he died of his injuries on Monday.

Known as the Kentucky Kid, Hayden won the 2006 MotoGP world championship with three victories that season. He competed in MotoGP from 2003-’15.

Tommy Hayden, Nicky’s brother, released a statement Monday afternoon on behalf of his family.

“On behalf of the whole Hayden family and Nicky’s fiancée Jackie I would like to thank everyone for their messages of support – it has been a great comfort to us all knowing that Nicky has touched so many people’s lives in such a positive way,” Tommy Hayden said.

“Although this is obviously a sad time, we would like everyone to remember Nicky at his happiest – riding a motorcycle. He dreamed as a kid of being a pro rider and not only achieved that but also managed to reach the pinnacle of his chosen sport in becoming World Champion. We are all so proud of that.

“Apart from these public memories, we will also have many great and happy memories of Nicky at home in Kentucky, in the heart of the family. We will all miss him terribly.

“It is also important for us to thank all the hospital staff for their incredible support – they have been very kind. With the further support of the authorities in the coming days we hope to have Nicky home soon.”
