(Cookie @ Jul. 01 2007,12:20) Throughout the years with my experience with the Hayabusa I have seen and heard of stock chains giving way with minimal mileage under various types of stress.
My advise; The stock chain is garbage - replace it as soon as you take possession of the bike ! ! !
I run a 'RK530GB-GXW (this is a 'W' pleated O-Ring that retains that much more lubrication over 'X' type rings), EK530ZZZ (favoured by turbo people has a very HIGH tensile strength) ,,
anything is better than that time bomb spinning on your drive train!
If you don't believe me,,, ask member 'Busa444' how lucky he was when his chain gave way or read his thread for yourself

Broken Chain at 2000 miles!!
ANDdddd, it was his billet sprocket cover that SAVED his water pump, engine case, etc., etc. Could have been more expensive than just deciding on buying an after-market non-violent chain.
Some of you virgin Busa owners, and never to talk down in a condescending way,
NEED to hear some of the essential bits that should automatically be added to your bike
AS SOON AS YOU BUY THEM!
FOR SAFETY-
1) Replace Stock Chain
2) Billet Sprocket Cover
3) Billet Stator Cover
4) Replace you stock brake pads with EBC 'HH' pads or other high sintered alternatives.
5) Braided Brake lines front and rear.
6) And re-valve your forks for your weight
