2004 National Arenacross Series champion is Canadian rider, Darcy Lange, riding for Team Green Chevy Truck Pro Circuit Richmond Kawasaki. Coming into the weekend, Lange had an 85 point lead over second place Shogun Motorsports Factory Yamaha's Tommy Hofmaster, and after pulling out three main event wins and staying ahead of Hofmaster in three out of four main events, Lange earned enough points to secure the championship, with a lead of 97 points.
Lange rode well all weekend and the championship came down to the 250cc main event on Saturday night. He led the first couple laps but then started to fall back and it looked like something was wrong. Lange landed hard and was in a little pain, and was 4 seconds behind the leader. He pushed his way back up to second place quickly, battling with John Dowd until the last lap. Coming around the last turn before the catapult jump finish line, Darcy passed Dowd for the win and put the entire crowd including his family, sponsors, and representatives from Kawasaki and teammates to their feet. A champagne celebration followed the awarding of the number one plate to the new champion
