Why Champ-Street is crucial course for beginners and season riders?

This video is about course that every rider should take with Yamaha Champ School. There are online courses and also courses with professional race instructors teaching track racing and also for street riding. The same track racing principle also applies in street riding especially in curves, twisties, mountain and canyon riding. Why not learn from professional race riders? Today's motorcycles are built not only by motorcycle engineers, but also with professional GP Riders input. I have taken Champ-U online and in this video I have taken Champe Street.
