How AMA MX and SX Numbers are Assigned Hot

The AMA recently released the numbers assigned to AMA Supercross and Motocross riders for the 2010 season…but what do these numbers actually mean?

Riders do have say on what number they get, but must choose based on availability. These numbers are assigned by process.

Here’s a breakdown:

Number 1: This number is assigned to the series champion, which will be James Stewart on the San Manuel L&M Yamaha.

Numbers 2 through 9: The champion from the previous year (such as Chad Reed, 2008 champion) may choose a permanent single-digit number if available, with the exception of Number 4. The AMA has reserved Number 4 exculsively to Ricky Carmichael through 2011.

Numbers 10 through 999: If a rider finished in the top 10 of combined championship points in Supercross, Motocross 250 and Motocross 450 in the previous year, he or she has the option to choose a career two-digit number, if available. The rider may also choose a three-digit number.

Also, riders who finish outside the top 10 but in the top 100 in combined championship points (Supercross, Motocross 250 and 450) in the previous year may choose a two-digit from the available supply of numbers.

If two riders are tied in championship points, the rider with the best moto finishes chooses his or her number first, unless one of those riders competed in only one series (Supercross or Motocross 250 or 450). These ties favor the rider who rode both series.

If a rider doesn’t earn at least one championship point during the previous season, he or she will lose the number issued to them. AMA will then give them a new number; special consideration is given to injured riders.

Also, lower three-digit numbers (100 through 125) are traditionally held for past or current champions from a non-U.S. series who participate in Supercross or Motocross.
