LAKEWOOD, Colo. -- Ken Roczen raced to his second straight 450 Class victory Saturday in the Lucas Oil Pro Motocross series' Thunder Valley National, finishing second in the first moto and winning the second.
Last week in Sacramento, California, the Red Bull KTM rider swept the motos.
Suzuki's James Stewart was second overall. He won the first moto and was third in the second.
KTM's Ryan Dungey was third with fourth- and second-place finishes.
Roczen has a 12-point lead over Dungey after three events.
"It's early to really say anything (about the championship)," Roczen said. "I feel like I'm riding good right now and I feel strong. I got a good jump (in the first moto) but didn't get up the hill well and had to fight my way through. I made some adjustments to the bike (in between motos) to make it easier to ride and it paid off. I just want to keep clicking (races) away like I've been doing and stay healthy."
Kawasaki's Blake Baggett topped the 250 Class, winning the second moto after finishing fourth in the first. Honda's Justin Bogle was second, finishing third and second. Yamaha's Jeremy Martin, who swept the motos in the first two events of the season, was third. He won the first moto and was sixth in the second.
"I wasn't prepared coming into the season due to an injury right before the opening round, but we've been testing and getting to where we want to be," Baggett said. "When you haven't won in a while it starts eating at you and I wanted to stop (Martin's) dominance, so I just went for it. We're headed in the right direction and there's still 18 motos left, so anything can happen."
Martin was a 26-point lead in the standings.
