Immediately after winning his AMA Superbike championship, Hayden was tapped to join not only Honda's MotoGP racing efforts, but what was arguably the premier team in MotoGP racing: Repsol Honda. Hayden also became teammate to the defending series championValentino Rossi. Hayden was seemingly unfazed, and in his first year of MotoGPracing (2003), he finished fifth in the championship points standings while riding Honda's RC211V, an achievement that won him the Rookie-of-the-Year award. In 2005, Hayden finished third in the MotoGP championship points standings behind Marco Melandri and series winner Valentino Rossi. In 2004, however, Hayden had a difficult year and was widely critiqued, luckily he answered critics with his first win in 2005.
