These lessons are a great idea. I wish they'd had this series online when I started riding street bikes. However, there's no substitute for an MSF or other training class. I took the beginning class, and then took the experienced rider's course--once before I broke my arm, once after I broke my arm, and once on a larger bike. It's really fun and you can do the practice exercises they teach you anytime on your own. My husband and I even bought the MSF group riding video when we rode across country so we could learn to use hand signals. And no, I didn't break my arm on the motorcycle.
I am always surprised at how many people are taking the safety classes in San Angelo. Too bad there isn't one designed to protect motorcycle riders from car drivers!
