Why do you want a busa again? For commuting? Buy something comfy. A CBR600F4 has loads more power than your current ride and is pretty manageable and comfortable too. More than enough bike for 90% of the riders on the road and too much for some. As many experienced forum members have noted, the first timers that aren't successful with the Busa are either dead or have given up riding so you won't be getting any feedback from them. Read some magazine reviews and watch some tv reviews of the mighty Busa. Most, if not all, will warn that it is for very experienced/expert riders only. The writers usually speak from experience.
Best thread ever.
More power to you.Go get one. Buy used and they are cheap and plentiful, aftermarket parts is also endless. 35-50 mpg will be your mileage. They suck on the freeway for a 60 mile daily drone. I had a 60 mile one way commute and bought another motorcycle (ST1100) just for that commute.
And welcome to the madness.

go for it....but be damn sure to load up on safety gear.... helmet(must have) jacket, gloves, and pants. they could save your life if something bad happens. check out this link...gear would have saved her alot of pain and suffering. 
I am 46 and I have only been riding since 2008.
I bought the 2008 busa as my first bike, very easy to handle, tame as a cat in the city.
The busa will only go as fast as you want it to.
I only dropped my bike once a week after I got it because I was waxing the chain and did not have a rear stand at the time.
I say the busa is a great bike for anyone. Since 08 I put 24.000 miles on her
But to me when ya boil it down it's just a pair of wheels with a engine attached to it. Also, it's not like I planned to buy one and hop on the freeway, I'm not nuts nor do I have a death wish. I would ride it around town for several months to get used to it first. I see it like this a Corvette is considered a fast & powerful car but I sure do see a lot of older gents rolling in them. Some have mentioned that you have to know yourself to decide, well I think Dirty Harry said it best... "A man's got to know his limitations!" And I know mine. I work at night so I've got the freeway mostly all to myself and even though the scooter could do 70 mph (when it worked) I was always in the slow lane. A coworker let me sit on his Suzuki (don't know which one it was but it was a 1000) and it felt lighter than my scooter. He was actually surprised because he said it was one of the heavier bikes. He offered to let me ride around the parking lot but I declined, I didn't want to risk dropping it. I'd like to get a used one because it's cheaper and if I don't like it I won't feel so bad about buying it. Plus, I don't like the newer ones (2008 & up) I hate how the back looks. The one that I really want is the 2006 limited in white (don't know if it came in other colors). Some have said they are very expensive to insure so I got a quote, only $400 bucks for the year, not to bad. I'd say I'm pretty much sold on the idea but I still have a lot to consider before I make a decision. So why don't I start with a smaller bike? In a way you could say I did. The first bike I had was a 50cc scooter, rode the hell outta that thing and yes I know it's not exactly the same. When I was young I wanted a Yamaha Vision because it didn't have gears (why don't they make Hayabusa's like that?) and I really didn't have a clue on how to shift a motorcycle. Years later I bought the 260cc scooter used and had to ride it 60 miles on the freeway. Yeah I was scared outta my mind but got used to it in no time. Now that I want to move up to a motorcycle I have no interest in buying several, I just want one. If I like it when it wears out I'll buy another, if not then so be it. I do have a few more questions...
