I'm close to buying an 07 CBR600rr and just wondering if there's anything in particular I should be focusing on? Any common problems, issues at all? Anything weak at all? I'm a good 225 lbs so how's the stock suspension? I'm planning Ohlins shock with perhaps some stiffer springs and valving up front? How's the fuel injection? Does it really need a PC if you go with a slipon pipe? Thanks.
