welcome...glad to see at least one other 07 600rr owner join. As for you bike how do ya like it?? I am in love with mine....I mean it I'm actually in love with it, ask my wife.
You got the red n black one so I would say mayby some rim stripes..
I put a power commander and a two bro's pipe on mine with a custom map, it did make a noticable difference....But it was $$$$'cy I would say for the money if ya wanna give it more go , do a -1 with a +2 front and rear sprocket swap. Very cheap mod but very effective!! I just went with a -1 front on my 07 and it made a HUGE difference.
here's a good site for 07 parts I've ordered from them before and they took care of me..
