Go do some reading and ask questions on http://www.psychobike.com/ a lot of guys on there that do nothing but drag racing. If I had to choose between a 1k and Busa it'd be the Busa hands down (even tho its ugly) way more comfy, way more manageable than a 1k (don't get me wrong if your an idiot Busa will kill you just as fast) the after market parts list for the Busa is unbelievable. In the end you are the one that has to ride the bike and be happy with it so go with what you like and take it easy on the throttle until you get some seat time on it. And most important of all respect the power of the bike and if you are afraid of the bike you have no business being on it.
