if you look at R bikes and the CR up to today. they have gone from 130-150hp in the year 2002ish to 180-190 today.
11:1 around vs 13:1
that and some minor rpm gains. (that said i think that gain is due to CR)
There are ofc more in the background like better injection, cam systems and intake tech but thats minor details?
