I have a 2005 zx10r with only a Jardine slip on and the butterfly exhaust valve removed. For some reason, i noticed that my top speed stays at 175 steady. Thats at around 10K in 5th gear. It doesn't waver at all and never actually gets to the supposed 186 mph limit. My bike is a California Model so I'm not sure if that matters. Any ideas on this? I know i may need to valves adjusted. I have about 25K miles on it.

You went down 2 in the front and kept the 39 in the rear and still only lost 9 MPH? Did you remove the governer.

To the best of my knowledge there is no speed limiter on the 1st gen 10R. It is only limited by wind resistance and gearing

So 1st gen riders should be able to surpass the 186 mph barrier?

IT is not a barrier it is only where the speedometer stops the bike can go faster if you change gearing modify engine nitrous ect.....

Well they hit the 186 in the top of 5th gear. So it sounds if you shift to 6th then it should continue to accelerate but the speedometer won't say it is though?

dont forget weight factor. 1hp=7lb ish. so, if you a hefty american, it aint gonna get up there anyway. also, there's not a regulator but speedo's stop at 189mph on all stock liter bikes

There is a top speed limiter on all bikes from the factory. They started a gentlemans agreement after te first busa came out and broke the 200mph barrier stock. That was like 99 or 2000 something. After that all sport bikes have a top speed limiter.

Yes and No lol The 1st gen 10R is not limited, the speedo just stops reading. The bike will continue to accelerate as evidenced by the rising RPM's

Of course rpm will keep rising when the speedo stops. BUT just because your tach stops reading at 189 does not mean your going an actual 189 when it stops this is why your rpms will keep rising. Stock gear will only go low 190's unlimited.

THIS
There is no limit in the 1st gen ECU like there is in many other bikes. It will keep pulling at full power regardless of actual or indicated speed. You are only limited by wind resistance and gearing on a 1st gen 10r.
In your Busa example, the ECU actually limits power output to limit the top speed, hence the "de-restriction" mods that are necessary to fool the ECU into allowing maximum engine output.
Weight does not technically affect top speed; weight only affects acceleration.

I had them cleaned, sonic cleaning and they precision matched the spray. Had to send them away. Its a must on injected bike at some point. I did all this when the fuel pump quit and changed the cam and stuff. It needed it, lots of Jennnings and Daytona tracks days on it.
By the way my speedo stops reading at 189. I know this because I am geared
-1/+2 which means I am going slower than what I am actually reading on the speedo. In 6th gear topped out it will say 189 I might be doing 170 to ???, if I am lucky don't really know or care its fast enough. Then to start the slow down process to get ready for the inside part of Daytona.

Has anyone actually tested the 1st Gen with stock gearing to see how far it will go up to in 6th gear RPM wise? Also from what we've said on this forum, it seems as if the 1st gen zx10 has a higher top end than any of the other zx10s. 4th Gen included because it's limited by the ECU. Am I correct?

Alright squids, let's get something straight here, so far nobody's mentioning the >7% spedometer error thats built-in to the stock bike! All the jap bikes have similar errors built-in (cars, Harleys, and some euro bikes have a lesser error, like 2 or 3%). Therefore, for you to be doing a true 185 mph on your Gen 1, the speedometer would have to say 197 or 198.
Of course this doesn't happen. From the 2002 model year onward, motorcycle manufacturers agreed to electronically limit the speed to no more than 186 mph. But this "limiting" is done at the true speed, not indicated speed. If the bike is not capable of doing a true 185 mph in the first place, no electronic speed limiter is required.
This is the case with the Gen 1. Although its power-to-weight ratio is quite impressive, the smallish fairings render it aerodynamically draggy at high speeds. This bike was designed for road racing, not top speed. A friend of mine has a 2000 Busa (i.e. before they started installing limiters). If everything is perfect, his bike will do 194 mph true on GPS. However, his speedometer needle is bouncing between 215 and 220 mph! There's a lot of guys with elecronically limited Busas and ZX-14s that think they're going 200 mph (because the speedometer says so), but GPS or a radar gun will show they're only going 185.9 mph.
A good running Gen 1 could indicate 189 or 190 on the speedometer. But a high quality GPS will reveal that you're only doing about 178 or so. If it's ultimate top speed that you want, you got the wrong bike. But if it's a trackday bike or a hooligan bike (wheelies n' hellraisin) that you want...you got the right bike!!

First off
Slow down here a little :heyyou: I was the Moderator that got a notification your first post needed to be approved before it can be posted live on the .NET :wink:
Now back to your statements of Squids, I guarantee almost everything possible about the 1st Gen ZX10R has been Mentioned on this site/Investigated and CONFIRMED!!!!!
Your #s are Wrong many of the 1st Gen ZX10Rs did up to 186mph out of the box and many Mag reports showed the same. Many on this site showed GPS confirmed top speed runs of 186mph. I personally put ~11-12 percent error with a SpeedoHealer and hit the deserts of Mexico and showed 180mph with last top speed recall but that was with -1/+1 gearing so it was most likely around 176mph if I was off a percent or 2.....but shows it’s possible I was in thin Air and no PCIII and with good air a stock geared ZX10R should be able to get close or up to 186mph.
....The 4th Gen ZX10R confirmed by a Kawasaki REP is the ONLY ZX10R ever Restricted for TOP SPEED.bloo

Thread revival, glsd I found ur posts blooseph. I was worried when I was told the gen 2 did infact have a limiter after being told numerous times it didn't. Planning to do a run tuesday to break the deuce and started getting worried. All calm nowFirst offto the site but go introduce yourself first before you start going off.![Image]()
