Only concern on 1100cc is the weight which is around 600lbs. This gonna be a lot difficult for slow speed and on the high traffic area. You live in rural area then you might not have to worry about it much.
The power on 1100cc isn't much more than 650cc but it accelerate faster and you can feel the power all the time. You have to make sure to pratice on throttle a lot. Pratice a lot on slow speed, u-turn, 8 figure, and quick stop and you should be fine.
