Put new sprockets/chain on my bike today...WOW what a difference 2 down in front and 12 up in back if you don't know what I'm talking about the sprockets.. have teeth stock my 02 R6 comes with a 16 tooth front so now I have a 14 and in back it comes with a 46 now I have a 58 tooth... just a hint if you guys try and do this or change the chain the stock one doesn't have a master link... you have to cut/grind it off.
