Haas driver Romain Grosjean has unveiled a Nicky Hayden tribute helmet which he will wear during October's United States Grand Prix.
The 2006 MotoGP champion died in May from injuries sustained after he was hit by a car while cycling in Italy. The American rider claimed three race victories -- two of which came in his title-winning campaign -- during his MotoGP career which spanned 14 years.
Following two race outings in the World Superbike Championship in 2002, Hayden returned to the championship on a full-time basis in 2016, with the aim of becoming the first rider to win titles in both categories.
