This club is all about good times, memories, family and friends.

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. (Please see sections 11, 12, 13, & 15)

 

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

If the women can get together 6 entries, they will have their own moto. This “Women’s Open” class will be for any Woman/Girl on ANY size or age of bike. She may ride mini cycles in either class also.
