I have the CBR250r. I picked mine up right after they came out (beginning of 2011) and I love mine. I admit I haven't ridden it much since I got the Z but it's also been insanely hot here in Louisiana and I don't ride without all my gear on.
Personally I disagree about outgrowing it. It's still plenty fast enough for me. If I really feel the need for speed, I'd rather do that with a seat belt on anyway.
