I have 2010 gsxr600. I love it. I am happy with my decision. I may not buy another gsxr600 because they are darn heavy for my short weak legs but that's only a problem for me! When I say it's heavy, I had 6' feet buddy try to back it up with both legs planted on both side of the bike had hard time pushing it backwards. Another friend who can only tippy toe it could back it up like it's nothing. Weight of the bike MAY be a factor for some but you can learn to live with it.
Do not let me discourage you, it's beautiful bike, a lot of pros swear that it's got the best motor and with good suspension and tires it'll be on par with the R6.
