I agree with most everyone who has already posted on this topic. I am 68 years old, 6"2" and 235 lb, and for such a small bike (compared to my stateside bike, a VStrom DL650), it seems to fit me pretty good. Plus, I ride mostly 2-up with my Thai girlfriend and even loaded it handles and rides surprisingly well.
That said, the sportier seating position on this bike does cause some discomfort in my wrists, especially in traffic where you're constantly clutching and braking. I live in Thailand winters and was able to rent a CBR before making the plunge and I recommend that OP do the same if at all possible. As for your height though, no problem.
If you're used to a cruiser or multi-purpose bike like the VStrom, the CBR will feel quite different. My VStrom, with its high seat and upright seating position was the most comfortable bike I've ever ridden.
But this new bike is a wonderful machine in all respects. Honda has produced a real gem with this engine providing big power and responsiveness in a tiny lightweight package. Plus, I got 86 mpg riding 2-up on a recent road trip. Beats the hell out of my VStrom!
