Perhaps none of the MotoGP riders have been affected by the loss of Marco Simoncelli more so than Valentino Rossi. Not only was Rossi “like a brother to Marco,” but the Italian was deeply shaken over his involvement with Marco’s accident at Sepang. With both Edwards and Rossi putting on a strong face publicly, the rest of us can only imagine the thoughts and grief that most be occurring internally. Everyone processes their grief differently, and one of Rossi’s more cathartic endeavors this weekend is to honor Marco with a special helmet for the Valencian GP. More photos after the jump.
