I picked my 2008 R6 up on 1st March and am still running it in; however, having changed from a 2000 GSXR 600 i can tell you that you made the right decision! The R6 goes well and handles even better! I am not the most confident rider when it comes to bends, but you really can trust this bike to take you round. A slight movement of the hips and she just leans over and takes you round!
All i would say, is that this bike will KILL you if you dont treat it with respect! It is a monster in comparison to my 2000 GSXR, which was quick enough for a new rider!
So, go steady but enjoy it. Go slowly and you will get more looks from jealous bikers and frustrated pedestrians! Go quick and you will overtake everything capable of travelling on tarmac...but being a new rider you will probably die!
Enjoy!
