Excellent read. If you haven't subscribed to MXA, then you're really missing out. This latest article hits the nail on the head with kids transitioning from 85s to the four strokes. I've always advocated that the kids step up to a 125 2 stroke first. And it seems mxsports is going in the right direction by adding the 125 BC class for the kids. Anyway everyone should read this article. Reference Motocross action magazine (2015) December. Ten things about 250 four-strokes and kids. Page 112.
