06 ZX10R Actual Top Speed 170mph
Motorcycle USA did a Literbike review, had this to say about the 10's actual and indicated top speed...
"Then it was time to go for a big number. I kept the ZX-10's throttle pinned after running the quarter-mile, and it continued to pile on speed at a ridiculous rate. In seconds the speedometer was reading more than 180 mph, and then climbed slower until it hit 186 mph. Then back to 185, then 186, then 185.
What did I prove (aside from being stupid enough to go that fast)? Two things. First, the speedy Kaw's computer has the Euro-mandated 300 kph (186 mph) speed limiter, which, by the way, cuts in very gently, unlike a rev limiter. Second, when you see 186 mph on your Kawi's speedo, you're actually only traveling a paltry 170 mph, according to the VBOX, an 8.6% error."
Here's the rest of the test...

So the speed limiter isn't going off actual speed but indicated speed, so the literbike's tops speeds are determined by speedometer error. I'm wondering what rpm's it was turning? I'm wondering about the ZX14's actual?

Get a GPS and check for speedo error.

Oopps, for the test they fitted 180 Pilot Race tires to the bikes, the Dunlop Qualifier the 10 came with is a lower tire, the Pilot is taller, more speedo error.

Speedo healer would let her run free to max out as far as top speed goes......
more interesting to me is the 04-05 ZX-10R comparo on the dyno... 04 ZX-10R shows great linearity thruout the powerband (no dips) ....not that 06 ZX-10R is awfull.. just not exactly what Kawi engineers were hoping for the 06 model...
Nothing earth shattering in differences.. informative more than anything ...good read....
Yeah I like my 04 ZX-10R... will continue to make payments as a totally satisfied customer....hehe
All these liter bikes are silly fast...

The oe tire is a 190/55 isn't it? Wouldn't that be taller, in your theory, than a 180/55 pilot? Also, why would a taller tire cause the speedo to think the bike was going faster?

Why would a slipping clutch effect the speed limiter?

Well i must have read about 6 mag tests on the litre bikes now and most have GPS tagged the zx10 at between 174 and 186.1mph depending on wet/dry windy or otherwise conditions so this sounds more like clutch slip to me. If you repeatedly abuse the clutch and then continue on for a flat out run its gonna be hot, surely better to let it cool and then do a top speed run from a gentle rolling start.

just got in from a ride about thirty minutes ago,and i had my gps strapped to the top yoke.I was going to make a top speed run but there was too much traffic.still I got it up to 160 m.p.h.on the gps,while my speedometer said 171.that was at 13,000 rpm in 4th gear . I was coming up on traffic so i had to shut her down. when I get up the balls again i'll give it another try somwhere else with less traffic.(2005 zx-10R magma red)

Hrm... strange stuff really. I was under the impression that the bike would not display a speed over 186mph too...... but a few weeks ago I saw an honest-to-goodness 188 "displayed" on the dash. Now, I know for a fact that my speedo/odometer are off by 7% (verified both not to long ago). Some math tells me that's a real 174... and I'd believe it. Bloody fast for a stock bike.
The strange part is that was close to 4500ft of eleveation, and the bike isn't fully broken in yet (about 1400 miles.. any bike I've ever had gets stronger untill about 3k miles). It might have been ever so slightly downhill, and the winds were fairly calm. I'm curious what would have let the speedo run over the 186 mark, if there is indeed some sort of limit. Thoughts?

I have a few GPS's and on the 10r and my Busa, the speedo was always out by 8.7%. R1 was only off by 1.5% or so...my 10R never could hit a true 186 on the GPS...she runs out of steam around 175...and then slowly gets to an indicated 186 whereas the Busa would pull hard right to the limiter...all 'bout TQ, Busa has it, 10R doesn't.

Regarding the 188 ... I have videos of one of the Test Mags and its 188 right there in the Video on a back stretch and it was Still Pulling in RPM.
It's a bone stock of of the crate with only 250 miles on it so you know it keeps building as the miles pile on.
I have read all of the rags myself and the numbers and opinions are wide but the On Board Video tells it all.

Interesting read Adam.
I thought the changes made to the '06 were aimed at increasing the bike's midrange power while still producing the same peak power. The article makes it seem like the '06 is more peaky in power delivery than before:
"Once wound up, it screams with an intense ferocity that'll make your eyes water. But below 8000 rpm, it actually gets out-motored by last year's bike (as seen here). Its torque peak now arrives 1200 revs sooner at 8300 rpm, but that wave is preceded by a relative lull. "

Very odd too.
When the 06 was 1st introduced I favored it a bit more than the outgoing model but now it's either way.

My local dealer has just been setting two 06 ZX10s up for racing and according to his dyno he could get neither to go beyond 186 even though it appeared there might still be a few more revs to play with. Obviously a dyno doesnt have any ram effect but then it doesnt have any drag effect either.
So the point to this.........god knows.
But if you really must go "flat out" then a restrictor of some sort is likely to call a halt to your playtime if the conditions would have allowed you past 186.
Also spotted my 1st advert for a "derestrictor" kit for an 06 ten so maybe there is a piece of electronic witchcraft going on.

We are racing a dragbike (2004 ZX10R motor) with 15/53 gearing (no speedohealer) and it reads 166 (on the cluster) in 4th gear pulls on the dyno at about 12,800 rpm. The dyno wheel registered about 110-112 mph. At the dragstrip, it will cut out at 131 or so mph which makes us think there is some type of built in speed limiter connected to the speedo because the cluster "thinks" it has reached 186 mph. Even after pushing the air shifter button, it immediately cuts out (we don't think we are able to reach sixth gear?) The bike ran 9.61 into a strong head wind and only was able to reach an actual speed of 131 before the engine started cutting out. It should be pulling to 141 in high gear at the end of the run., based upon our research and experience.
Does this make sense to anyone on the forum. I have spoken to someone from Kawasaki and although the ZX12 has a max speed of 186, he was not sure the ZX10R (04-05) had the same limiting device. Lastly, if, in fact, this is the problem, who manufactures the speedohealer? Thanks!

What kind of power is he getting from stock 06's?? I've heard as high as 168rwhp!

One bike was 161.9 and the other was 162.7 bhp rear wheel stuff both with less than 5 miles on the clock with cats and everythijg still fitted , both bikes now making near 180 rear wheel with a fullrace system and PC fitted with lots of dyno time to get it just right !
