The page has now the right back tire measure
190/50ZR17
http://www.kawasaki.fi/index.php?sivu=mallit&rec_id=2#
they also confirmed at Sumeko, the Finnish Importer/Distributor
(where I reported the error)
that the tire figures are offcial
(and I can see that they are now same all over the world)

147,2 KW @ 10500
138 Nm @ 7000
tank only 15,5 ltr
not for me with that fuel capasity - racetrack vehicle

Wow
147.2 kW x 1.34 = 197.25 Hp @ 10500 RPM
(5252 x 197) / 10500 = 98.5 ft/lbs @ 10500 RPM
138Nm x .7376 = 101.79 ft/lbs @ 7000 RPM
(7000 x 101.8) / 5252 = 135. 69 Hp @ 7000 RPM
we already know it makes 72 ft/lb at 2000 RPM
What a nice fat torque curve!
It is tuned lean and has catalytic converters.
Short duration cams for emissions.
another 10% should be easily extracted.
with cams, pipes and pc3 should get close to 200 rwhp................
Thanks VPN.

Holy shit we have a mathmatician. I hope your math is right!

yup. Guarantee the figures if VPN #'s are correct!
Basic hot rod math.
If you have the torque at any specific rpm.........
to find the HP at that rpm, multiply the torque times the rpm, then divide by 5252.
transpose for torque........
Hp = (RPM x tq) / 5252
Tq= (5252 x Hp) / RPM
Did the conversion to imperial first !
Kawi already gave the Torque at 2000 RPM .
78 ftlbs (?) @2000 rpm also equals 29.7 Hp @ 2000 RPM.
These must be crank shaft numbers . /\ /\..........
Rear wheel will be around 9 - 12 % lower.
Good pipe without cats , pc 3 tuning, and cams will make 200 RWHP reality.
Appears this motor has relatively short duration cams with decent lift to produce broad power. Long stroke helps bottom too.
Longer duration cams and better exhaust will be the ticket.
Piston speed at 10,500 RPM is 4202 fps.
11,000 RPM is 4402 fps.
Just some more interesting #'s.
Probably the only reason I payed any attention math and physics was because I wanted to make more Hp! ( liked biology too! - teacher was HOT!)

16500/pi ~5252.11312203
to use Nm as torque => conversion #~ 7120.90923749
to use KW and Nm => # ~ 9549.29658551
I was also doing my homework
:-)
