Trim your replies, please.  Thank you.

Or better yet, a Ducati 99x.

Yes... please do... ;-)

Clearly there's a little work to do on the air/fuel ratio between 5k and 9k
rpm, but it's pretty damn close to good!

You mean the 600 i4 torque curve is that steep as well?   my
sv's is about 45 degree angle... the RC's is almost vertical
and low in the rpm range too...

the 600 i4 doesnt start pulling at 2k  what?  more like 5k?.
and then the torque curve more or less follows the HP curve.
Notice with the RC45 that the torque curve preceeds the HP
curve and is almost vertical from 2k to just 2.5k.

Yeeeeeeeeeeeeeeeeah, ok!

pffffffffffft. Your own dyno chart disproves this. Maybe if you hadn't
gone blind from masturbating furiously to poor Mr. RC45 in the comfort
of your own shop you'd be able to tell. Let me give you a helping hand
of an entirely different sort...

A Gixxer 1000 makes over 50lbs. of torque at 2,700 rpm and it only
goes up from there. That's more than your bike ever sees at any point
in time. Including redline and impromptu roadside fantasy w.nk
sessions.

Your max HP is something the Gixxer 1000 makes at 6,000rpm. With only
errrr.... another 6,000rpms to go!

I can understand your silly "seat of the pants" comments. I've ridden
the literbikes and will agree they all do one thing really really
well. Make going stupendously fast feel slow. Until you look down at
the speedo that is and soil yourself, you have absolutely no idea how
much faster you were going in that turn that you usually do. Or even
want to!

Modern tech is like that. The chassis, radial brakes and trick-coat
suspension are all so full of feel and usability that they do the
business with no undue hysteria. In contrast your RC45, and every
other lesser machine generates so much noise and brouhaha when caned
at full tilt that it gives the uninitiated the impression of speed and
power, even though the cold hard numbers clearly say otherwise.

That's one reason I once went for the 600s. I want to enjoy fast at
90, not 150. The liters are just too damn good that they make any
kinda speed that one would do on the road a ho-hum break out the
pipe-n-slippers and read the paper on the gastank. Track only mate.
Why I'm currently on a Triple or why in an even more extreme case,
folks buy Harlies. So they can take that cobbed together piece of
domestic sh.t to full tilt and feel like it's going to implode at any
given moment. Which thanks to the resonance building in all the
vibrating fasteners isn't too far from the truth!

You're absolutely right that there's "no one home until 6k rpm", but
that's just a silly off the cuff impression, not hard data. That's
because the whole show goes from "Oh my gosh" to "Is my insurance paid
up?" when the powerband hits and when it does it generates numbers far
in excess of your teeny weeny 750cc peeny.

Face it natch, box stock supersports are generating lap numbers in the
hands of skilled riders that factory machinery was doing a decade ago.
If we do the math we realize that 1994 was actually MORE than a decade
ago to the tune of one excess year. So much technology that was
previously unavailable, so much new thinking that renders the old
titanium goody business obsolete, all earned with the blood sweat and
tears of continual refinement and failed experimentation.

And here you are, gonna tell us all that they way they did sh.t eons
ago is still hanging with today. Wait another ten years Larr, then
you'll look just as silly as the vintage racer you truly are in front
of the latest speed toys!

"Oh yeah, that there new ZX-10R ain't no match for my Kawasaki H2!"
Ha-HA!
