“Who’s that number 111 guy?” Look it up here with the 2005 AMA Supercross numbers.AMA Pro Racing has announced rider numbers for competitors in the 2005 AMA THQ Supercross Series and AMA Chevrolet Motocross Championship.National numbers are based on a system that allows past champions, current champions and riders who have earned a top-10 national ranking, to select and retain the same number from year to year. This system was established in 2002.Riders like Travis Pastrana (199), Jeremy McGrath (2), Mike LaRocco (5), Ricky Carmichael (4), and James Stewart (259), are all known by their rider number.”There’s a promotional value associated with a rider keeping a particular number,” said Steve Whitelock, AMA Pro Racing’s Motocross/Supercross series manager. “This allows the rider and his sponsors to develop an identifiable mark in connection with his image.”Current AMA National Champions can carry the No. 1 plate. Numbers 2 through 9 are reserved for past National Champions in active competition, or they may select any available number. Riders ranked in the top-10 in combined Supercross and Motocross points can choose a Career Number from 10-999 which they keep until they withdraw from competition or fail to earn a National point. Riders outside the top-10 in combined points are assigned consecutive numbers through 99 based on year-end points, but can request a higher triple-digit number when applying for their 2005 license. Riders outside the top-99 can keep their 2004 racing numbers by renewing their AMA Pro Racing licenses for the 2005 season before Nov. 20, 2004.
