Dear Steve
My vote is for blue.
When I went into the Suzuki dealer looking for a GSXR1000, the blue one caught my eye, and after never considering a 'Busa in the past, I fell in love with it, bought it, and have grown to love the bike in deeper depths after having had it for a little over a month.
The gold wheels add to the bike's looks, in my opinion, if they're clean. I have the unpopular opinion that the stock exhaust looks and sounds awesome. If I replaced the stock exhaust, I'd want something similar to Yoshimura tri-oval, dual-exit cans on each side of the bike. I don't believe the 'Busa's designers meant for one side of the bike to be semi-naked from the lack of an exhaust can.
I love the orange and black, too. I believe the orange and black looks a little more sporty than the blue, but the blue looks more mature and sophisticated, at least in my humble opinion.
BEGIN RAMBLE--
I just got my 'Busa out of the slower drive modes on Wednesday when I cracked 1000 miles. This bike is insanely fast. It's video-arcade-style fast. And dangerous. A 'Busa shouldn't be able to be purchased by anyone with less than three years of riding experience. Surely a 'Busa is nothing more than a death machine for an inexperienced rider with more bravado than brains. Even though I truly love my 'Busa, I must concede that it's very uncomfortable for me for more than thirty minutes at a time. Part of that is because I'm not used to riding. This 'Busa is my first ride in more than fourteen years. Another factor is that I'm morbidly obese, standing six feet tall and weighing about 265 pounds. I'm working on that. I understand that I could install Helibars and Buell footpegs for greater comfort. Of course, you're aware of all of this as an experienced 'Busa owner.

Whichever you choose, Steve, you're going to love it. Be careful, buddy! And congratulations on living in a world in which the 'Busa experience is your reality!
