Already representing the Japanese motorcycle manufacturing giant in both the AMA Superbike and Supersport series in America, the 24 year old from Kentucky will race a third bike for the Kawasaki Racing Team at the event in California, alongside regular riders, Randy de Puniet and Anthony West.Hayden rode Shinya Nakano's 2006 Kawasaki 990cc MotoGP bike during a test at Valencia at the end of last season and also enjoyed a brief opportunity to ride the new ZX-RR at Japanese circuit, Autopolis, recently. With his considerable experience of the Laguna Seca track, the team hope he'll raise their profile in front of a knowledgeable and enthusiastic American crowd and have some fun on the powerful, 800cc machine while he's at it. The young Hayden boasts an impressive pedigree. As part of the Hayden family racing dynasty, he was put on a motorcycle at six and began racing just a couple of years later, eventually turning professional in 1999. He came second in the AMA Supersport championship in both 2004 and 2005, scored fifth in that series last year and is currently running second in the 2007 title fight. In 2006, he won Rookie of the Year in the AMA Superbike championship. Furthermore, he's done well at Laguna Seca in the past, including gaining a Supersport win there in 2004.Both AMA Superbike and Supersport will feature as support races at the Monterey circuit over the course of the MotoGP weekend and Hayden will ride his Kawasaki ZX-6R in the latter, in addition to his wildcard ride. He won't, however, race his ZX-10R Superbike that weekend as otherwise he'd never be off the grid!
