Dungey took his first ever 450 class main event victory in Phoenix to take the point lead.

After an epic premier one week ago, round two of the 2010 Monster Energy AMA Supercross, an FIM World Championship, season didn’t disappoint as Rockstar/Makita/Suzuki’s Ryan Dungey won his first career AMA Supercross class victory en route to taking the points lead.

The night began dramatically when points leader James Stewart was involved in a frightening crash during his heat race. The San Manuel Yamaha rider overcame obvious pain to compete in the last chance qualifier where he took the win and qualified for the main event.

As the gates dropped, Dungey raced to his second straight SPIKE Holeshot Award, with Monster Energy Kawasaki’s Ryan Villopoto and teammate Austin Stroupe following, and never looked back leading all 20 laps of the main event.

“I’m just pumped on the nice performance (tonight),” said Dungey. “This is a big step in my career. I owe a lot of thanks to all the people supporting me. I’m glad to get this out of the way and I’ll never forget it. It’s early in the season and last week was tough. James was on it and I hope he’s ok. It’s just great to come out with a win here in round two.”

Stewart found himself buried in the back of the field alongside rival Chad Reed and the duo followed one another throughout the early part of the race until Reed attempted to pass the reigning champion on lap five, causing a collision and subsequent fall for both riders. Reed failed to finish for the second week in a row while Stewart soldiered home in 15th. Villopoto rode to a solid runner-up finish while San Manuel Yamaha’s Josh Hill landed in third.

Monster Energy/Pro Circuit/Kawasaki’s Jake Weimer captured his second straight AMA Supercross Lites Western Regional victory.

As the AMA Supercross Lites class blasted out of the gates, Monster Energy/Pro Circuit/Kawasaki’s Josh Hansen grabbed the SPIKE Holeshot Award with GEICO Powersports Honda teammates Blake Wharton and Trey Canard following in second and third, respectively. As the field entered the section before the first triple, Hansen lost control of his bike and suffered a hard crash. Wharton assumed the lead and would hold it until lap 12 when Rockstar Energy Suzuki/Canidae’s Ryan Morais made the pass with Weimer close behind. The next lap, Weimer made the pass for the win.

“I struggled a bit for some reason,” said Weimer. “I got my first win (in Phoenix) and I love it here, but I always struggle in the sand (section) every year. I made some mistakes in the beginning and never thought I’d be up here. This is kind of a surprise but it’s great.”

Morais finished just behind in second while Wharton held on for third.

Dungey currently holds a nine-point advantage over Villopoto in the AMA Supercross standings while Weimer leads Morais by eight points in the AMA Supercross Lites Western Regional standings.

Queenslander Michael Byrne was also a non-finisher after bowing out in the early laps, however good news came his way on the night that he’ll be replacing Josh Grant at JGR Yamaha for the upcoming rounds.

Speculation surrounded the paddock afterwards that Reed has suffered a broken hand in the incident that forced him out of the race, while it’s reported that Stewart may have broken some ribs.

Tempers flared following the crash with Reed allegedly making contact with Stewart’s helmet following the crash as the pair were getting up, before Stewart made his way to the Kawasaki pit after the race and reportedly pushed the #22 factory KX450F off the stand in an angry reaction.
