CBR600 low down "grunt"

As my brother was thinking of getting one I took a CBR600 (1999 model) for a
spin on the weekend.

Surprisingly I really liked it.

And in comparison to my last two bikes (CBR1000, VFR750) I expected to be
disappointed with low down grunt (or lack thereof).

Thing is I remember riding one about 10 years ago and I'm pretty sure it needed
a lot more revs to get off the line.

Did Honda seriously re-work the power/torque curve on this bike from the early
90's?

A few things have happened since then.

I mean, back then the Yanks were bombing Iraq, cops were booking
motorcyclists for speeding, Kawasaki were selling GPX250's...

As 600's have progressed, their power curves havent changed much at
comparable revs, just extended to higher levels to produce more power.
Electronics allow them to clean up lower rpm response, EFI even more so.
This means most gears are lowered from the earlier models and so for the
same road speed in those lower gears, they pull harder, and can get off the
line easier.

Occasionally you hear mentioned that the newer bikes are not as 'torquey' in
top gear roll on's, presumably because they are still geared for around
5000rpm at 100kmh in top gear, so as not to bee too noisy or busy in feel.

I sit to be corrected.....

PS, where I'm coming from is from seeing a comparison of earlier v's later
600cc power curves overlaid each other. They were incredibly similar rev
for rev, until the older bikes tailed off and the new bikes kept reving (and
thus producing more power).
