there are better choices.
you could start on anything.. harley, haybusa, ninja 250, r6.. however its much easier to learn the basics on a smaller/lighter bike (ie ninja 250) and there is MUCH more room for error.
i personally started on my 04 r6 w/ ZERO riding experience ever.. and iv put 16k miles on it in about 5 months and still havent fallen or anything -- in fact iv been to the track twice and placed fairly well.
its all a matter of self control and how serious you are about riding..
you can kill yourself on any motorcycle, a ninja250 will still accelerate faster than pretty much any non-sports car and falling off of a 250 vs falling off a 600 or 1000 is all the same, its just that you will be much more tempted to push a super sport bike (r6,r1,gsxrs, ect) than a little 250 because they can do so much more.
respect the motorcycle and learn about riding, gear, how to handle emergency situations on it.
the only thing about getting a brand new bike w/ no experience is that you probably will drop it (most likely from something stupid too -- forgetting to put the kickstand down or stopping with the handle bars no straight ect.. its common for new riders) and that is lots of $$
dont expect to hop on a 06 r6 and be able to woop on everyone (or anyone for that matter), its 90% about the rider.
