"The 65cc and 85cc races during the AMA Arenacross Series season often produce some of best racing of the weekend," said AMA Arenacross Series Director Jayme Dalsing. "Now that these kids get a chance to race in front of a huge crowd at a supercross race it says a lot about the caliber of the racing and the talent of the competitors. What makes it even more exciting is that for the first time ever, the AMA will recognize the winners of these two races in May as National Champions, awarding the youngsters with a coveted number one plate."As the 12-race AMA Arenacross Series season travels throughout the country from January through March, the 65cc and 85cc races across five regions will determine who lines up on the gates in May. The top four riders from each class in each region will stamp their ticket to the showdown in Vegas for a pair of 20-rider main events.The 2010 AMA Arenacross Series kicks-off in Grand Rapids, Mich., January 8-10 from Van Andel Arena.
