Classes

2019 Classes, number plates and letter designators have changed! 

Please see the 2019 Supplemental Rules for additional Information.

  • All riders must display the correct background color, number and letter (indicator) for their class and division on all three number plates. Numbers shall be a minimum of 6” tall and letters must be a minimum of 4” tall. This rule will be strictly enforced in 2019. If a racer arrives to a race without an assigned number or it is not properly displayed, they must purchase a temporary number with appropriate letter designator and color bar for their division at registration for $10.
  • It is the riders responsibility to enter the proper class. Failure to do so will result in loss of all points earned. If you ride the A class at other like events, you must enter A class at a SIDRA race.
