I know what you must be thinking, not this old chestnut again. But hear me out. I am in the market to buy something on two wheels and I am looking at either a 2011 CBR600RR ABS or a 2011-2012 CBR1000RR. My previous riding experience was mostly gained a few years ago riding a RVF400 i had for about 1-1.5 years. In this time I learnt some smart things, and done some of the silly things you shouldnt do. I never came off, never had any issues or accidents. Now Im older (27) & wiser and I have my full licence I am looking into buying one of those bikes mentioned. Having never ridden a 1000CC, rode a CBR600RR a few times just a quick spin nothing major. What should I be considering? Would it be too risky going straight to a 1000CC after so much time off a bike? I have heard the whole dont do a 250 to 1000, but is the step from a 400 to 1000 any different? Just looking for some honest opinions and suggestions about things I should consider before choosing which bike to buy. Thanks!
