ALL D Class Riders:
4 wins or 5 second place finishes or any combination of the two and you get advanced. If you're fast enough to win the D Class, then you need to start the series in the C Class. If a rider has previously won a championship (any series any class) that rider cannot ride a D class. When you get advanced, you don't take your points with you. The D Class is a beginner class and a chance to try racing to see if you like it. It isn't a place to plan on winning a Ultra Series championship.

Youth D Class Riders:
You can race a 2nd class, but if you place in the "TOP 30%" you will be out of the D Class. This Youth Rule is based on 10 rider minimum class.
Series Tie Breaker
If a tie is recorded in the final point standings the tie breaker will be the
best finish in the last event that either or both riders attended in that series.
