I have 10+ years riding and I am glad for every days worth of experience I have prior to getting my R1. With 10 years experience I am having to learn to ride the R1. It is not a machine to be taken lightly. It is true for all modern sport bikes that they can get you into a lot of trouble, but more so for any of the new liter bikes. The problem is that most people don't know how to control all that power. It doesn't take much skill to put that power to the ground in a straight line, yet people all the time are flippng their R1s. Now think about that same amount of power in the turns. You ask the bike to power through a short straight between turns, the R1 will jump to 100+ in the blink of an eye. Now you are coming into a turn posted for 25mph and you are doing 100. Take the time to learn the skills needed to get the bike slowed enough to make the turn.
Get a used 600cc, i.e F2 or F3, and take the extra money to go to safety schools and later track days/school. If you do you can learn to smoke fools on liter bikes on your 600cc. Then you can go get a liter bike and learn to be fast on that. If not you will be one of the fools on the liter bike getting smoked by ninja 250s on the track.
