Okay tekmoe... On a track a 600 and liter are going to be close to the same, unless it is a really tight track. I know more people that track R1 than I do that track R6.

On the streets you never use the extra power of the liter, but you do turn a lot so a 600 is hands down better for the street riding.

And the part about not getting an R1 for a starting bike has almost NOTHING to do with responsibility. If you are stupid and irresponsible it does not matter what you are riding, as you mentioned. It has to do with being able to handle a bike. If you start on something that large your learning curve will be many years longer than if you start on something smaller and learn the basics without all of the power first.

All in all, if you want GOOD advise and not amateur advise go to a biking forum like motorcycleforum.com Lot of good advise there.
