It may be a little small but the gearing on an 883 is lower than the 1200 so you can always have it punched out to a 1200. This bike is great for going around corners it has a quicker acceleration than the 1200.
My first bike was a 883 and I'm 6'0 265 but at the time I weighed 220 it was a lot of fun now I ride a road glide but that is after several bikes in between such as the Dyna super glide, heritage softail, heritage springer, an Indian four which i still have and Indian chief, Indian scout.
every one of these bikes has their own redeeming qualities
