Since its inception in 1947, not long after the storm clouds of World War II were blown off the European continent, the sport of motocross has officially been considered a World Championship discipline of motorcycle racing by the Federation Internationale Motocyclisme (FIM). In those 50 years there has been one rider, more than any others who have become before him, who is considered the single greatest racer of all-time. So much so he’s now commonly referred to as the GOAT, or Greatest Of All-Time.

His name is Ricky Carmichael, and by the time of his official retirement from the sport during the September of 2007, he had won a mind boggling 15 AMA Pro Racing Championships, 150 AMA Pro Racing races and the prestigious Motocross of Nations. In fact, in the very final race of his career on Sunday, Sept. 23rd, 2007, befdore 40,000 fans Maryland’s Budds Creek MX Park, Carmichael led Team USA to victory at the ‘07 Motocross of Nations. Upon retiring, “RC” as he’s known in the MX industry, moved immediately towards his next goal: Leaving a mark in National Association of Stock Car Auto Racing. Now the driver of the Monster Energy-backed #4 Chevrolet Silverado, Carmichael is currently competing in the 2009 NASCR Camping World Truck Series as a member of a high-profile Kevin Harvick All-Stars team. All this withstanding, RC still gets on the bike and last summer smashed the Step Up World Record in 2008 with a leap of 36-feet. “When I set the world record at 36-feet, I think I could have gone even higher,” says Carmichael. “No matter what, it was real thrill to break the record.” Next stop: The 2009 Summer X Games.
