SUGAR GROVE -- Corey Powers is like many 16-year-old boys. He is shy, likes sports and is hesitant to talk about personal accomplishments.

Powers' demeanor would be less surprising if not for what he does while racing all-terrain vehicles. His aggression and speed helped him gather two national championships in 2011 in the American Motorcyclist Association ATV Motocross Championship race series.

"It's fun." Powers said. "(I like) hitting all the jumps."

Powers, a sophomore at Berne Union High School, won the 90cc CVT class and the 90cc senior automatic class in 2011. He raced an 11-week schedule at different tracks across the Southeast and Midwest and came away with 14 wins in 22 races.

After starting to race in 2007, Powers slowly progressed each year. He competed in one national race in 2008 and two in 2009 before racing a full schedule in the two AMA race classes in 2010.

Powers finished third in the 90 senior automatic class and fourth in the 90 CVT in 2010 before winning both in 2011. The improvement has been constant for Powers, who picked up the sport out of pure love for competition.

As quiet and unassuming as he is away from racing, Powers is equally amped up and assertive on the track. Racing ATVs is an expression of his personality and desire to win.

"He just likes to compete," Corey's father, Tim, said. "He likes to be aggressive, and as he gets good at it, the more aggressive he becomes."

But this year marks a new challenge for Powers, as he will jump up to the 450 C class. The lower classes all have age limits, and Powers is moving up to one where he will be among the youngest participants.

"It will be harder," Powers said, "being younger (than the rest)."
