Those bikes are not for new riders. They are too powerful. I've ridden motorcycles for a while. A 600 is perfect for the novice rider. I know a few people that has bought R1's as there first bike and they even said its scary. You have to very careful, you can't be stupid on those, your asking to get hurt. You have to get use to the power. The power on the R1 comes alot sooner, you don't have to rev it passed 8k to get power like the R6. Just be careful.
People wont appreciate my opinion on this remark but anybody that buys anything larger than a 600 is wasting money, you really dont even get to see the potential of the bike as long as you stay on roads and highways. Even on most racetracks they barely tap into what a 1000cc bike has. 1000cc bikes are not good for new riders either, they are much heavier and will get you hurt alot faster, you should save some money and get a nice 600, and then as your skills mature, get a 1000 if you must
I worked at a Yamaha and Suzuki dealer for a few years and I have seen many people get too much bike for them and then have to end up spending $4 grand fixing the bike after they dropped it
