My first bike 12 years ago was a Katana750. I was dumber then and never bothered to take a MSF course. It only took me 3 months to wreck that bike and severly wreck my body. My inexperience led me to high side. I will just say that I was going to fast, was afraid of the front brake and had never even heard the term "high side". I was in a cast from my stomach to my shoulders with a badly dislocated and broken shoulder and in a wheel chair with a fractured hip. That sucked! *
My next bike a year later was a Harley Fat boy. This time I took the MSF course and rode the way a Harley should be ridden... like a cruiser. I bought several more bikes and built a couple of publicized customs.
However, in June of this year a friend convinced my to get back in Sportbikes. I called the dealer looking for an 06LE. They had one left. the first thing the Dealer *asked me is "How long have you been riding?" I explained that I had not ridden a sportbike in 12 years and that the time in between had been spent on cruisers and choppers. He did his best to talk me out of a Busa.
That being said, I bought it, have customized it and ride it as often as possible. However, I never forget its power. The 12 years since my last accident have given me the opportunity to mature. I don't need to go from 0 to 80 between lights, don't need to ride wheelies and I don't need to be able to lick the ground when I am cornering.
I think the bike is fine for a first time rider. As many have said here, "Any bike can kill you". It is all about respecting the machine and more importantly your own skill level.
