Answer:
What do you mean? I can probably answer any question involving Motocross (Motorbike racing) but do you mean how do you participate? Well, the way I race, is I go to big national races, where a bunch of other people race too, against me, but only in my class, (bikes around my size and people my age) and we race dirt bikes, basically some people only race for the fun of it, but some people only race for the prizes. If this wasn't your question or not a good answer, I'm sorry.
