Power to weight numbers for 2000

[OB_Bob]

Technological evolution--What a great time to ride!
Just roughed some numbers of some of the Bikes i was considering and others in or near the same class.
Yeah wet weight is more accurate, and the HP numbers are approx. rear wheel. But, the point is look at the numbers now! Bikes beyond the average rider's capabilities.Most are .70+ hp per kg. How to get this power to the ground and keep the wheel down?

Model Dry Weight rwHp Hp/Kg's
ZX12R --210 --166 --.79
929RR --170 --133 --.78
R1 --175 --133 --.76
Busa --215 --159 --.74
GSXR750 --166 --121 --.73


Remember the Thunderace
YZF1000 198 --130 --.66
or the old 900RR
CBR900RR--180 --122 --.67
ZZR1100 --233 --140 --.60
'99 XX --220 --143 --.65
Yes, these are good times!

Bob, I didn't realize that Chicago was using the metric system. Why not do the same thing with pounds and crank hp since we have a better idea of what those numbers are. Where did you come up with 166rwhp for the 12R? Highest I ever saw was 161, and that was Rickeys "worked on" bike. We know the R1 and 929 have about 150 at the crank and the Busa has about 175, from what I here the 12R has about 173-175 at the crank.

Great info Bob! Must be cold for you to have all this time on your hands...

Muzzy's test bike turned 169rwhp on their machine with their stainless/CF system installed with no re-mapping. Anyone is more than welcome to call and they'll gladly share that information with you. Ask for Doug Meyer.

Hey Bob. Take a look at the far right column and you see that the busa comes in #2 instead of #4 when you plant a rider on top of the bike. The busa achieves this good number with a skinner 150 pounder, the fatter you are, the better the busa and the 12 will be by virtue of their hefty HP numbers.

As I said in my first post--The point is the power to weight numbers now vs. 5 years ago are fantastic. 5 years ago no STOCK bike was making .70 hp per Kg. (.30 + hp per lb.)
RPMpower--multiply Kg's x 2.2 to get lbs.

Most Hp numbers came from Bike Mag. or others that have dynoed.
The 12R has been quoted at 178 PS on the Kawasaki website, which I believe is approx. 175 Hp at the crank. What Muzzy does I don't care about for now, and any dyno number on a given day can vary from another elsewhere. This was a stock comparison and dyno numbers are approx. I know R1's that only made 130 hp and others at 140 hp?

12R-----463 lbs.-----166 rwhp-----.358 hp/lb
929RR---375 lbs.-----133 rwhp-----.355 hp/lb
R1------385 lbs.-----133 rwhp-----.345 hp/lb
Busa----474 lbs.-----159 rwhp-----.335 hp/lb
GSXR750-366 lbs.-----121 rwhp-----.330 hp/lb

XX------488 lbs.-----143 rwhp-----.293 hp/lb
ZZR-----512 lbs.-----140 rwhp-----.273 hp/lb
900RR---396 lbs.-----122 rwhp-----.308 hp/lb
GSXR----394 lbs.-----116 rwhp-----.294 hp/lb
