I know the reason for the teather rule.Why is it not in the rwb class rules? Thats what i'm getting at. I have raced at the professional leval and expert leval in Enduro,Hare-n-Hound,Speedway,trials(novice only there),And have been on a motorcycle since 1966. My father was a professional flat track racer.I am just trying to read the rules correctly.It doesnt mention the teather or a stabilizer in the rwb class,othere than you cant use a stabilizer as a turn-lock-stop. Is the rwb class an adendum to the record-classes? Thats all I'm trying to find out. Thanks for the advice.
