It seems to me that you have a sensible head. I, too, took the MSF course in VA and found it very valuable. I figured that this was a great way to get introduced to riding and way to figure out if you're cut out to ride one. Interestingly enough, my first bike was a 96 F3. This is definately an excellent bike. Prior to buying my first bike, I've was reading all the sportbike mags and drooling over them. The legendary CBR F series have been almost always been leading the 600 pack. It's hallmark has been the all around sportbike that can be used to take a pleasant stroll or a serious contender on the track. Depending on your riding experience, it can be an excellent first sportbike; although, I literally didn't have any riding experience besides the MSF course, I went ahead and started out on a spanking new 96 F3! Never looked back. It's Honda realibility and excellent ergonomics. I am 5'8" and was only able to put my tip toes when at a stop. You 6'3" frame should be good for when at stops but I'm not sure how it will feel when you're running. I guess, ideal would be for someone who's about 5'10-6'. Remember to take things incrementally when riding; especially starting out. There's no glory in crashing. Speed will come when you're riding smoothly. Look at Troy Corser. If you can't ride smoothly, (having the right entry/exit speed, braking, shifting, etc.) you're probably over extending yourself. And if you don't heed yourself, sooner or later, you will run wide and crash. I would concentrate and riding "smoothly" than riding fast and having to readjust. Again, I believe if you ride smoothly, speed will come. I think I've heard from racers that riding smoother actually results in shorter time around the track. Watch the video, the Privateer. In any case, ride safe and good luck. Remember, the point is you're supposed to be enjoying this, not scaring oneself.
