Didnt we just have this thread like 500 times last month?

And my opinion is the Honda CBR600RR or F4i.
The R6 though is also a sexy Bike and even though I hate gsx-r's cus everyone and their moms got one, they are starting to grow on me as the newer ones look pretty nice.

So
CBR600RR
GSXR 600
R6

One of them....

Or smaller.
Like stealth said youll want a more forgiving bike as your first.
