Where do I find dirt bike or atv classes for my 4 year old in Southern California? She's been riding since last year with me training her but I want her to be trained by a professional now. Probelm is that all of the ones I found only take ages 6 and up, which is dumb as hell because actual racing starts at 4. I can sign my daughter up for a race but I can't enroll her in a class to learn how to ride? How the hell does that even make sense? Where do I find one that will teach kids under 6?
