If you are a "B" rider, age 15 on January 1st, turn 16 on January 2nd, you are considered to be 15 all season. All "C" riders that have 6 points paying finishes to calculate a RPV of greater than 11 and have raced "C", Beginner or Youth prior to January 1, 2010 will be advanced to "B".
You may advance on your own ability / competence. A "C" rider that is not advanced in 2012, is classified as a "C" rider for the entire 2012 season, unless it is determined the rider is not legal for that class ... the same applies to the "B" class.
All "B" riders carrying a RPV of 15 or higher at the end of the season will be advanced to the "A" class. No rider, youth or amateur, can be forced to compete in the "A" class until January 1 following their 16th birthday. Riders under 16-years old may advance on their own ability/competence.
Based on AMA rules and various track rules any rider who lines up on the line to compete in a money paying class, is no longer considered an "amateur"... whether money was earned or not.
Riders are responsible to be competing in classes they are legal for.
APs earned for participation in the 250 or 450 skill level classes will not be combined. If you are advanced in either, it will apply to both.
All "C" riders carrying an RPV of 15 or greater at the end of the season will be advanced to the "B" class.
No rider is to be classifed as a "C" rider if that rider has
A rider may not be advanced to the "A" class through the RPV system if they were previously designated a "C" rider in the same year.
************************************************
50-65cc riders advancing to 80cc machines that normally finish in the lower 30% of the smaller bike class, and/or normally have non points paying finishes (using the scale for advancement of other riders), MAY be legal to ride the D class ... this does not define that you ARE legal. Each rider will be considered on a case by case basis.
Most events do not offer D (beginner) skill level classes for 50-65cc riders, therefore, it is by circumstance, and not by choice, that these riders are riding age groups commonly referred to, practiced and accepted as, the next level UP from beginner. Hence: you cannot be both a D rider and age group rider, unless OPEN skill is clearly defined. No rider is to be penalized with permanent advancement, when the option to ride the lower class is not an option. Many of these riders have not acquired the skills that are necessary to be competitive in the 85cc age groups.
Mini bike riders advancing to big bikes: The same scale being used for "C" class riders will apply to mini bike riders. All SR mini bike riders will advance to "C" unless any of the preceding paragraphs apply or he / she carries an RPV of 15 or greater.
