Love my 250, I usually ride alone so its not so "slow" until I start riding with 600's , thats the only time i want to upgrade!the 250 is so much fun in the twisties... other than that its quite slow LOL
Well Id say its only good for tighter twisties, on high speed twisties the 250r tops off or struggles too much to get to speed to actually go into the corners nicely.
I recently rode with a few 600's and 1000's , was able to keep up (if not pass a few times) with them in the twisties no problems, its not until the straight away that I get passed but I catch right back up in the turns.
