Two points to consider: I've never seen newbies torn apart for asking for advice on literbike as first bike, in fact 90% of the questions we get are of this category, and yet many of us do take the time to give our best suggestion, as such is the case.
Secondly, just to get facts straight, it's the lap time where R1 and R6 are very close (or any 600s VS 1000s from their respective manufacture for that matter), i.e. tracks with twisties and straights, and given two riders of equal skill, these performance figures are apparent. But in straight 1/4 mile, R6 averages about low 10s, and R1 averages about low 9s, stock to stock under experienced riders. This is nowhere near as close, as 1 second is a great difference in the world of racing. For street riders, it may not be much, but it does determine the power delivery of each bike. Even if R1 is only "1 second" faster, it is true this bike will pull from ANY rev range, and clutchless wheelie is easy in any gear, except for 6th.
Having said all this, to Josh: Get an older 600 cc pre-2000 era or Suzuki SV650, you'll be much thankful for the skill you'll quickly gain now, which will be really handy for the big bikes. Because with big bikes, you have no room for error, but small bikes do tolerate these mistakes and give you room to learn.
