Yep I started out on the 636 pre and post MSF course. In all sincerity just take it easy, don't abuse the throttle until you're fully comfortable on the speed/acceleration. Ride a lot too, it'll get you more comfortable with the bike. Just remember to take it easy, don't be a show off. As far as learning curve, on my first day bringing the bike back from the dealership I had NO prior riding practice other than when I rode dirtbikes back 9 years ago, which isn't alot of hours. I made it home safely, just think about what your learned in MSF and apply it, you'll gain most of the riding skill within a days worth of riding.
