Another piece of the puzzle is the physics of your motorcycle. (i.e. Really understand WHY applying a brake or rolling off the throttle mid turn may cause you to crash)
Being a prudent rider is the name of the game, but you can't be very prudent if you don't even understand the environment you're operating in....
+1 - for every rider, IMHO minimally once every ten years. Better to do it once every five years. Riding theory changes, skills get rusty, new (to the rider) instructors focus on different areas, and different classes focus on different skills.
There is a reason motorcycle cops train under competent teachers as much as they do.
