Motorcycle racers are among the most passionate athletes in the world. They wear every win, crash, and championship title on their sleeve, and the best of the best leave the track Sunday afternoon having left nothing on the table. Want to see raw, unedited emotion? Just watch a clip of Nicky Hayden after winning his first MotoGP World Championship in 2006. Real frustration? Rewind the same video and watch Hayden's reaction to being taken out by Dani Pedrosa at Estoril, a crash that would nearly ruin the Kentucky Kid's chance at winning the championship that year.
