Congratulations, and be forewarned - the fuel injection is not new rider friendly. If it does not have a PCIII, get one installed, it honestly helps.
I've seen seasoned riders wreck because of the throttle response - It's not about the power, it just is immediate.
The 599 might of been a better selection for a first motorcycle, but screw that, you've got it, it's a heck of a motorcycle, you'll love it.
Don't let "the class" make you overconfident, be very easy with the throttle, especially when new tires on on, and have fun, smile a lot, and ride ride ride.
