Z1000 HP vs Ninja 1000 HP

I just saw this on Motorcycle.com, just wanted to let everyone know. I also found out that the Ninja 1000 is electronically restricted to an undisclosed top speed. I must find a way to fix this minor issue.:dance:

Thanks

During a trip to the dyno Kevin noticed that a Ninja 1000 (which has a different airbox than the Z) tested on the same day as the Z1000 cranked out a couple more horsepower from 9000 rpm to the 10,500-rpm rev limit.

Is the Ninja 1000 Geared Differently?? Because I'm pretty sure the Z1000 is gonna top out (I haven't ridden this quickly) at a theoretical 155mph due to the gearing. This would be under basically optimal conditions w/ the wind at your back and in a full tuck...

Can't imagine the Ninja, given it's closeness to the Z would even need an electronic top speed restrictor... It's never gonna make it to 180mph w/ the stock gearing.

Ahh good to note... So with 1 less in the back, you're looking at a 3mph difference (upward) for the Ninja.

Z1000: 154.8mph with 15/42 at 11,000rpm.
Ninja 1000: 158 mph with 15/41 at 11,000rpm... Can't see why they'd be limiting the speed electronically at all.

Yeah, thanks for sharing... It's always interesting to find other minute differences between these bikes.

He might have seen that much difference in 2 Zs tested side by side with production differences. Could also have been how they were broken in. Break them in too gently and they won't make as much power. I've seen 5hp differences in identical models.

Even though the Z is supposed to have a bigger airbox and shorther gearing, the Ninja beats it in the quarter mile and in top speed. The full bodywork makes a big difference in performance.

I think the Ninja's speed limiter is the rev limiter. The Z won't get there due to aerodynamics but the Ninja will easily run right up to and bounce off the rev limiter.

I took the below text from the MCN test on the Ninja 1K:

"Interestingly, the Ninja’s final drive gearing has been changed vs.
the Z1000. A 41T final drive sprocket replaces the Z’s 42T final
gear and might be expected to reduce acceleration slightly in
favor of more relaxed cruising speeds. But our testing found just
the opposite. Quarter-mile times actually dropped from the
Z1000’s best of 10.64 to 10.50 secs. and its zero-to 100 mph time
dropped from 6.45 secs to 6.28 secs.—this in spite of an 18 lb.
weight gain due to the Ninja’s extra bodywork (from 480 lbs.
wet to 498), and a tiny decrease in both dyno-tested power and
torque (.69 hp and 1.06 lb.-ft.) compared to the Z1000."


They also got a top speed of 152.8 on the Ninja but don't say if it's drag limited or governed, with the wind, against the wind, etc. I doubt the Z will get close to that with no bodywork to slice through the air.

I don't think anyone can say the Z produces more power based on this comparison as random cause variation is likely to account for more than a .69 hp difference from bike to bike. As Squidilis said, 2 identical bikes that rolled off the factory conveyor back to back are likely to have a greater variation than that.

If you read the article, the z they tested in 2010 was 4 hp more than the one they tested for this test. This proves what everyone is say. Also environmental conditions play a large part in dyne runs. Synod are great for seeing dips in powerband but for peak horsepower they are more like guidelines than definite numbers

i read recently in cycle world magazine, that the ninja 1000 is electronically limited to 100hp, in the usa. they went on to say that the z1000 wasn't, because the lack of a full fairing would limit top speed by itself. maybe they did it for insurance reasons, or to separate the ninja 1000 from the zx10r, in performance specs....tomp

I think you need to brush up on your reading comprehension, and your grammar. How would they electronically limit HP? Top speed yes, but not HP.

If I remember correctly, I think they said it's electronically limited to 156 or 158, not sure, but according to the MCN article I referenced it doesn't have to power to get past 152.8 so it's electronically limited to a speed it can't attain anyway. At least in stock form.

Well, mine just did well over 100 HP on the dyno, and that was measured at the wheel, so any info about an electronically limited 100 HP is incorrect.
