Suzuki RM-Z450 riders finished first and third in the latest round of the Grand National Cross Country (GNCC) Motocross Championships in Kentucky, USA, in the series' first-ever all-Australasian podium. The event, round seven of the 2008 series, was the first time an American rider hasn't finished inside the top three. New Zealand ace Paul Whibley made a last-lap move to win the challenging three-hour event - his second successive victory - and closes to within 23 points of championship leader David Knight.
