Race Rules
AVDRA has a few classes (i.e. Support and Mini Classes) that are not offered in some other regions of VMX racing, and AVDRA uses the AHRMA Rule Book as a rough guideline to follow for classes and safety gear.
(Please see sections 11, 12 & 13)
All classes will race 2 moto’s, usually 5 laps each, and scores from each moto will be added together to determine overall finishing positions.
There are 3 Skill Levels for all the Bike Classes:
Novice, Intermediate and Expert
There are also Age and Gender Categories for all the Bike Classes:
40+, 50+, 60+, 70+ and Women's
Series points and year end awards will be given to competitors that compete in the qualifying number of races during the season. Support classes will not earn any Iron Man points.
Women’s Open Class
