im not in to the whole ZX14 or Busa whats better. I bought my 06 Busa because I wanted a awesome bike but wanted one that was proven and had no glitches to worry about. I have been reading posts on the 14 and some people are having issues with a Knocking noise in the engine once warmed up and overheating issues. There is also alot of complaints about no low end grunt below 5000. IMO even if a Busa is all new for 07 I would wait and see because u allways here of first model bikes just not being as good as they should be. Hell the only problem im aware of with my busa is the Kick stand and thats easily fixed. I have ridden the 14 and yes its also a awesome bike but no way I would buy one until I knew for sure what was causing this knock so for me its the Busa all the way. Suzuki-Kawasaki-Honda-I dont care just give me a powerful and reliable bike thats comfortable and I will buy it thanks Suzuki.
