here is what I have read, 999 02 is 124bhp
999S 02 137bhp
999 05 is 140 bhp
999S 05 143 bhp
you will get a difference from bike to bike and there are lots of power figures that are different from these,
the early 999 S has more power at the top end and dont run as well as a straight 999 very low down in the revs, mine like 3 thousand revs +.
this is just my view.
hope it helps
