I'm new. I stepped up from a CBR125r. New black '09 Ninja 250r about 3 weeks ago. Bought it used with 1500kms, in mint shape... not a scratch, $4000. I'm lovin' it, and enjoying the substantial step up from the 125.
I used to have a CBR125 for commuting to work, but boy is that bike small... I have an old CBR600 that comes out a bit in the summer and swapping from the 600 back to the 125 was like getting on a bicycle! (that always made me smile a bit though - if you haven't ridden one, I'm not joking - it's tiny... and about as fast as a bicycle too) ;D The Ninja is my new commuter (and weekend hack while the CBR6 is in hibernation) and is far more fun and it even feels like you're riding a proper bike after riding something a bit bigger!!
Enjoy your Ninja Adb... oh, and 'Welcome' btw
Is this the bit where I'm supposed to mention pics?...
