I agree too. Sure i've rode like a 40 CC scooter before like 12 years ago in HS but never rode a real bike. My friend told me it was easy once you get the hang of it. So when he bought his 04 R1, i bought the guy who sold it to him; his wife's 01 R6.
Sure i was nervous about the shifting, my only hang up, but after a few days i had it down and it was pretty much like second nature. a few more weeks of respecting the bike and reading all i can about leaning, push steering, traction etc etc i feel good on it.
Sure i'm not expert and i don't drag knees nor do i fool myself. But everyday i get more comfie, and i have no qualms anymore about taking it WOT through 2 or 3 gears. Also i've come close to dropping my bike. Putting my foot down on gravel and slipping etc but i'm 6'2" and i've had no problem recovering nor have i ever came close to dropping it cause of something stupid.
R6 is a great bike to start out with, and as long as you know your limits like these other posters have said then you can grow into it just fine.
i've had it 1 month, put 2500 miles on it and can't get enough. I love riding and glad i finally took the leap after thinking about it for about 13 years.
Now about the R1, my boy's R1 has full graves exhaust, 2 more teeth on the back sprocket and power commander set to high and that thing is sick scary fast. Feels like a it just wants to be released from it's cage. Love it. One day, just not today.
