The Red Bull Honda WSBK team paid tribute to their rider Nicky Hayden who died on Monday after being hit by a car on Wednesday while riding his bicycle near Rimini in Italy.
The Ten Kate Racing-run Red Bull Honda squad released a statement saying the late 2016 MotoGP world champion's professionalism and fighting spirit made him a fans favourite and he would be sorely missed by all who knew him.
Hayden stayed in MotoGP up until 2015 and in 2016 switched to the Superbike World Championship and claimed a race win in Malaysia.
The Honda statement reads: "Throughout his career, Nicky's professionalism and fighting spirit was greatly valued and carried him to numerous successes, including his childhood dream of being crowned MotoGP World Champion with Honda in 2006.
"As well as being a true champion on the track, Nicky was a fan favourite off it due to his kind nature, relaxed demeanour, and the huge smile he invariably carried everywhere.
"Nothing says more about Nicky's character than the overwhelming response expressed by fellow racers and his legions of fans over the past few days.
"Jackie (fiancée) and his family are truly grateful for the countless prayers and well wishes for Nicky.
"The 'Kentucky Kid' will be sorely missed by all that ever had the pleasure of meeting him or the privilege to see him race a motorcycle around a track, be it dirt or asphalt.
"The racing world says goodbye to one of its dearest sons. Rest in peace Nicholas 'Nicky' Patrick Hayden."
