Welcome WetRock, I have ridden both the Blackbird and the Busa. They are both great bikes, and the Blackbird does have Honda's reliability, good Power, decent handling and decent looks. However, it also has freakin linked brakes, a bit of a wallowy numb feeling in the corners, a substantial reach to the bars, and some serious mass carried a little high. It is a sweet bike, but it doesn't talk to you, and you cannot adjust the suspension to try to get it to talk to you.
Getting on the Busa the first time was like being re-born. On paper there doesn't seem to be all that much to seperate them but when you ride it is immediatly apparant the the Busa is more than the sum of it's parts. It feels alive, it talks to you, really gets you involved, then you twist your right wrist and ALL doubt is immediatly pushed from your mind... The Motor is amazing, and the chassis can keep up. It is hard to explain but the acceleration is truly amazing. I have found the Hayabusa to be the most emotional bike I have ever ridden, it has character and personality/attitude. I have found myself more attached to this bike than I have ever been with any machine. It is also the first machine I have EVER purchased that has lived up to all it's press and Hype, you read all about the Busa experiance and I was sceptical, I mean really, I have been on fast bikes before, it cannot be all of that, right? Wrong, I have found it to be everything it is claimed to be and more... Truly I feel it is something really special, a fine bike in every way and it has a soul.
Now there are a few areas that need looked at. You will want to buy some braided front brake lines,(Factory lines lead to some pretty crappy brake feel) and if you really want to get extra comfy buy some Helibars and maybe a Dubble Bubble screen. Set up a rear tire fund, as you will be going through them at a pretty good clip. Small issues for sure, and none of which really detracts in my mind.
As for ridability? The Busa is a complete (though Torquey) pussy cat below about 6K RPM. It's nimble for it's size, and is really unintimidating if ridden gently, completely Mr. Hyde if you will. But...Get it out in the right location, (EMPTY, FAMILIAR) Twist the throttle to the stop and Doc Jekyl shows up to show you the Beastly side of the Busa, the shear joy with witch the Busa spins the speedo is something not to be missed, 150-160 MPH is addictive and easy and the beast never stops pulling, even past the 160 mark...it's amazing. Slow back down, and hell, put the Missus on the back and it will toodle around town and country just as happy as can be, no drama, no complaints.
Am I biased? Well of course I am, but in all fairness I really can recommend the Busa to anyone with some previous riding experiance, a level head, and the maturity enough to know when to unleash Doc Jekyl and when to walk around with Mr. Hyde. It really is just that damn cool!!! IMMHO
OH, and waiting just a couple of months to see what happens in 04' is a really good idea. You may have the opportunity to hop on a sweet new Honda or Busa, or you might be able to get a better deal on an 03 if the new flavours do not appeal...
