'600 I4' are the cool bike, but for city driving / commuting they are like tits on a bull.
You have fantastic top end power but nothing down low, all the fun starts over 7000 rpm.
They are a very fun toy, but for use a transportation a 650 V2 is a far better bike, you have power in the usable 2- 5000 rpm range and better ergo ride city/commute and longer distances.
The 6000 - 10000 rpm range the bike will do it all.
Also do not get an R6 that would be to much bike start small get the R1
