This is the first picture (click on image to enlarge) of the special livery which Fiat Yamaha riders Valentino Rossi and Jorge Lorenzo will use during this weekend's US Grand Prix at Laguna Seca.

The livery is made up of small black-and-white photos, sent in by fans via the team's website. 500 spots were available on each bike and it took less than 30 minutes to fill the fairings.

The livery is being used "to celebrate the upcoming launch of the modern-generation Fiat 500 in the USA".

Reigning champion Rossi and 2010 title leader Lorenzo will ride with the livery for the first time in Friday practice.
