The stock rear sprocket on the 2009 hayabusa is 43 teeth. I was wondering if I can install a 45 tooth rear sprocket and use the original chain (almost new).Thanks for your answers in advance. yamanista jg
"Ripley" is in good hands. Giving up my passion for a machine is insignificant if it will help me win my battle to be with my Daughter. I will never give up that fight! Yes, my ex is the Devil!

Yes it will work with stock chain. You can even go to a 46 tooth spocket with the stock chain I put on the 45 and love it pulls harder but still has plenty of top end.
