Motorcycle racing superstar Ricky Carmichael had his inaugural tour of the NASCAR world last weekend at Phoenix International Raceway and it was a whirlwind event. Carmichael, 26, a native of Clearwater, Fla., who currently lives in the state capital of Tallahassee, is a 15-time American Motorcyclist Association champion in Supercross and Motocross, amassing a career record 144 event wins. The next step in his career is NASCAR, and Phoenix was his introduction. He was the guest of MB2 Motorsports owner Bobby Ginn and co-owner and general manager Jay Frye, for whom he'll toil next season as part of the organization's driver development program. Carmichael took a break on Sunday morning to meet with the media and discuss his motivation to go stock car racing, how he perceives the challenge, the path of his short-term career and the impact of having Mark Martin as a teammate.
