Top Speed limited or Not ?
Starting a new thread on this but IS the top speed limited or not one would think this was an easy question but both sides of the fence seem to be arguing their for or against with equal vigour.
Does anyone have any proof?
A dyno print out, drag strip fying mile run or something?
Personally i think it is limited but ONLY because my dealer couldnt get a bike past 186 on his dyno but i havent got a print out to prove it or otherwise.
Over to you.

the question at hand....
is it limited by gearing, or HP, or is the timing retarded ?

hehe... I know that mine is certainly not limited at the 'indicated' 186, as I've seen 190 indicated before with a few hundred rpm to spare. I haven't had it up to an actual 186 yet (considering the 7-8% speedo error), but I don't doubt for a second that it would get there if I were down a bit further in elevation.

My question is very similar..and that is: is there something in the stock ECU that will not allow the ignition to send a spark to the bike if the stock ECU "thinks" the bike is traveling beyond a certain speed. My bike has been on a dyno, doing 4th gear pulls and the speedometer was registering 166 mph. Keep in mind that the gearing was altered from stock (17/39) to 15/53, thus the speed counter at the countershaft was off by a mile! With that gearing, the bike would hit the "rev limiter" at 134 mph, actual speed on the dragstrip. Our calculations indicate that we should be able to pull 141 mph (plus or minus) at red line in 6th gear..
Maybe someone on here understands our dilemma? Thanks!

Why not just call Kawasaki? Wouldn't they tell you? If not, why not? You are just asking about your purchase which you love?

Ive seen my clock read 187mph so im assuming that thiing is reading correcty and the bike can easy get 190mph given a large expance of road and lack of coppers

Ivan at rockland county said it is not limited, its geared from the factory to hit redline at 186 in 6th. So no need for the gentelman's agreement limiter

There is a post on this forum somewhere and a guy had a GPS mounted on the upper triple of his 06. He had just done a run. His bike was stock with about 1200 miles on it and he took a photo and posted it. It read 188mph. Another guy said his GPS on his 06 read 187. Doesn't sound limited to me.

Since our last post, we have installed the speedo healer and corrected 29%. Hopefully, the motor will not flatten out in 5th gear now!

No limiter on the 10's.
My son has ran 202mph on a Coby Adams built 10 at Maxton with the stock ECU. He also has ran 193 on Don Smiths 10 at Maxton for Sport Rider magazine. Will be back to Maxton on the 20th & 21st on Dons bike, this time spraying.

I have had my speedo to 197 before, although i believe most bikes are 10% off above 100 mph. It definately was not out of power, I was just out of room. I believe that was 5th gear with stock gearing.

...interesting side note on the 06 10R; It isn't limited, but it stops -reading- anything past 189 in mph. It pulls another thousand rpm, but the speedo won't budge past 189. Wierd heh

Put the bike on a dyno and top it out in 6th gear... I put my 12r on the dyno with the bonneville box and extended ecu it pulled 200mph in 6th gear and was shut down by the dyno brake with a lot more in it.. Best way to check is on a dyno or real world with gps..
Seen a 10r at the dyno drags.. It ran a 1/2 mile at 186mph topped out

Not sure about the others but my 04/05 runs to an indicated 299 kmh and just comes to a stop will not accelerate past this point despite still having much more left fitting a kit ECU and modifed loom reprogramming the PC111 and the bike has indicated 322 kmh ( uncorrected ) on more than one occasion on the track of course.
This bike has considerable modifications in addition to the above so it may be possible that differnt country spec bikes have alternate ecu programming from the factory, I have asked our factory contacts via the race team with no diffinative reply on the subject?

My 04 shows 187, then backs down to an indicated 186, then buiilds again to 187, then backs down to an indicated 186, etc. etc.
Sure seems like it was "atrificailly" limited by design to me...

Stock 2006 ZX10R. Here it is in writting  ...
"A side note: During acceleration testing in our secluded test area, I had the chance to take a couple of the bikes to high speeds. I saw 173 mph on the CBR's speedo, but the VBOX logged just a 162-mph maximum, a 6.4% error.
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 link to the test ...

Funny how some here are seeing over 187 indicated but this guy does not? According to him it accelerates straight up to 186 indicated but then backs down. Actual top speed 170 mph  .

There ya go.... an 06 at real close 5000ft above sea level. It's hard to see the tach with that lighting, but with the stock gearing (the speedometer was in fact 8.6% off from the factory...) it pulled to 189 with another 1000rpm or so before the soft limiter would cut in.
Fun stuff.... but it's a real bastard to do that and not bbe able to tuck in all the way because of the camera

Did you read what Dan said. It's not limited. Good Lord people, proven at Maxton. Enough already.

Couldn't a person remove the chain and then shift the trans into 6th gear and just rev it up and see how high the speedometer goes up to? Sure the bike wouldn't be going anywhere but since the speed sensor is off of the counter sprocket the bike would think that it was. I personally don't think that it is limited and really it doesn't matter to me. I will never get mine even close to finding out if it is.

Damn dude chill. One person saying one thing, one article showing something else, no reason to get bent out of shape it's not like it really matters that much. According to this article it is, according to this person it isn't. Do you have a ZX10? What do you see on your (8% inaccurate) speeometer?
