Re: CBR600 or GSX-R600
get whatever fits you better.
i ride all sorts of bikes all day long. i like most of them, some just suit me and my riding style more than others.
personally, i like the 600rr over the gixxer. not that there's anything wrong with the suzuki, i just feel more comfortable on the honda.
more comfortable= easier to go fast on
it's all down to personal preference.
hell, i ride a 400cc dirtbike with 17" rims and street radials, and a cbr600 with dirt bike bars and no fairings, so my tastes are a lil odd anyway...lol
