Suzuki's Ryan Dungey made history with his Motocross championship at Southwick last weekend.

History was made last weekend when Rockstar Makita Suzuki’s Ryan Dungey wrapped up the 2010 AMA Pro Motocross Championship, adding the outdoor crown to the Supercross series he won in May.

The 20-year-old rookie’s achievements make him the only first-timer in the history of the sport to clinch both the Supercross and Motocross titles in his first season, also ranking as the youngest champion ever crowned.

“This feels great,” explained Dungey. “It’s a lot of hard work and a lot of long weeks in the off season to prepare for this, but its all the better when you pull it off and win the championship. It’s not all me, everyone on the Rockstar Makita Suzuki team put 110 percent into everything they do and that’s all I could ever ask. We work well together and enjoy working together at the same time. It makes it fun.”

Legendary team manager Roger DeCoster is proud of Dungey’s results in his first season on the RM-Z450.

“What Ryan has done, no one has ever done before including McGrath, Stewart and Carmichael,” DeCoster said. “No one has ever won both the Supercross and a national championship back-to-back as a rookie. It’s pretty impressive.

“Sometimes, because Ryan is such a subdued nice guy, you don’t really realise what a big thing that he has done. I expect more and more perfection, but you look back and see that he is doing things that no one has ever done before – it’s pretty impressive.”

Dungey has made history winning a total of four national titles in the past two years. He won two titles in 2009, the AMA Supercross Western Regional Lites and the 250 Motocross championships, both on the RM-Z250, as well as being the hero of Team USA at the Motocross of Nations in Italy.

Now with the 2010 Supercross and the Motocross title in his possession, Dungey was named the captain of Team USA and hopes to keep the Motocross of Nations championship in the U.S.
