depends on what you want and what you like, personally I am a Kawi fan I own a 09 ZX6R and I bought a 2013 ZX6R in Dec. So far the 2013 blows the 09 out of the water, more torque and more top speed. Plus if its something you like then theres the traction control and ABS if you choose to purchase it. Personally I hate the traction control and wish I could disable it completely, but Im sure most people will like it... Either way its got all the new toys, BPSFF sperate function forks, FCC slipper clutch, TC, ABS, 310mm rotors...
If you go Kawi I suggest making the trip to St Onge in Barrie, best price I found on Kawi's....
