The official list of AMA pro numbers came out today and New York native Justin Barcia has grabbed the #51 as his permanent career number for his professional supercross/motocross career.  51 is a number he’s carried through the amateur ranks ever since he threw a leg over a dirt bike.  Here’s some throwback shots of Justin from 2005 and 2006 racing at his local tracks such as Walden, Winchester, and even Loretta Lynn’s. It’s time to get used to the #51 once again!
