just bought a new 2011 CBR600RR. havn't sold the ninja yet but planing on it. had the ninja for one year and put about 13,000km (or 8,000miles). i've had the cbr now for two weeks and LOVE it! such an awesome bike. gald i made the choice to upgrade; the cbr fits me better (im 6'). but i definitely am glad i started on the 250, learned so much from it.
here's a couple pics.
