Being or not being a "douche bag rider" has nothing to do w/ taking MSF courses. :\

Let's leave it at that.

 

Any real training you can get is good. I'm sure you're a very safe rider, but there is a ton to learn about the physics of riding and how to get the most out of it. I've been riding for more than 20 years and still have more to learn. At least give "Twist of the Wrist I and II" a read or watch the video. It will make the sport more enjoyable and a safe rider safer. Proper technique is safer than riding slow and not doing wheelies.
