I saw something on TV (motowold?) about a high school they have set up for racers. The best kids can go there and they have classes in the morning and
ride and train with supervision the rest of the day. A prominent ex-racer
(sorry I can't remember which one- there have been a lot of fast frenchmen) set it up. This undoubtably helps, but the I still give credit to anyone's talent and effort that can race at that level.
