But Dungey had more to prove at Chase Field in Phoenix Saturday. The 22-year-old Belle Plaine, Minn., native would go onto dominate in Phoenix, giving KTM its first-ever AMA Supercross victory.And the 2010 AMA Supercross/Motocross champion did it with style; he took the Nuclear Cowboyz holeshot, and went on to lead all 20 laps. This was following a fourth-place finish in his heat race.Ryan Dungey (Red Bull KTM SX-F 450 Supercross) says: “I was definitely motivated by my teammate tonight,” Dungey said on the podium. “I saw Marvin (Musquin) got second in the Lites main and knew I had to step up my game to match him and do well for our team. This win feels so incredible. The whole crew at KTM has been behind me 100% since I joined them in October and it is amazing to earn this win together!”Roger DeCoster (Red Bull/KTM Factory Team Manager) says: “It is not just our team in the US but the whole crew in Austria at our factory that have helped us get here. It’s amazing to get a podium in only our second race of the season. It feels really good that we were able to deliver for the people that backed us. We have proved ourselves with a win and intend to keep progressing.”With his wins, Dungey is now tied with Anaheim I winner Ryan Villopoto (Monster Energy Kawasaki) with 45 points after two of 17 rounds.
