This is the special helmet design, in tribute to Marco Simoncelli, which Valentino Rossi will use for the remainder of this weekend's Valencia MotoGP season (see below for further pics).
Simoncelli lost his life at the previous Sepang round, in a incident also involving close friend Rossi.
The special helmet design feature combines Simoncelli's red and white at the front with Rossi's usual colours.
Rossi stated: “I really miss Sic, and I still haven't completely realised what happened. I thought the least I could do was dedicate my helmet to him and to his number, 58.
"Here in Valencia number 58 is all over the paddocks, everyone wants to remember him. Sic, this helmet is for you!"
