MOTEGI — American rider Nicky Hayden, 2006 world champion, said Thursday he will retire from MotoGP next year to compete in the World Superbike Championship. The 34-year-old Honda man, preparing to race in this weekend’s Japanese Grand Prix, has announced his move to Ten Kate Honda from the next year. The move comes after Hayden spent 13 years in motorcycling’s elite division, a career which also included a spell with Ducati. From next year, Hayden will team up with Michael van der Mark, riding the CBR1000RR Fireblade SP as he bids to become the first rider to win both the MotoGP and World Superbike titles. — Reuters
