Hi, I need help on choosing the right sports bike. GSXR 750 (K4)/DAYTONA 675/2006 R6?

mark the R6 and Daytona are great bikes but the GSXR is in another league I think.you have the size and weight of a 600 which is great for commuting and twisty roads and the power that will keep up with and beat most 1000cc
