315km/h @ 10,600 rpm in 6th on a standard ZZR1400 from 2008 ?!?
Hello everybody !
Just bought my new ZZR1400 last week, and after running in the engine I did my first high speed test on a closed circuit. (well... a flat strech of a motorway nearby :-)
Surprise: 10,600 rpm in 6th !!! From my calculations, assuming the 30 km/h per 1000rpm in 6th gear, this equates to 318 km/h !
Am I the only one passing the 300 mark with a standard ZZR1400 or has Kawasaki removed the limiter on 2008 bikes ??
Mine came with ABS, although I don't think this matters...
Comments from other 2008 ZZR users ?
Cheers !
Pedro

How exactly was your actual speed measured? The Speedo on the 14 reads high by at least 8.5?% It's highly unlikely you hit anything close to that speed on your stock 14...299 is all it will do, without modifications to your gears /speedo.

Get a GPS and try it.
This should give you an actual reading.

Steve, I ignored the speedo gauge because it was stuck in the last mark slightly before 10.000rpm.
I calculated real speed (not gauge speed) by interpolating the 30 km/h @ 1000rpm in 6th gear to the 10,600 rpm that I saw last night.
I didn't measured the speed otherwise. I was about to confirm with a second run with my GPS on board, but rain has come pouring down :-(
I'll do so as sson as it dries out there !
Meanwhile, can anybody confirm this 30km/h @ 1000rpm on the stock 2008 ZZR1400 ?
And is the RPM gauge reading reliable ?
Keep'em flying fast ;-)

The Tachometer is also optimistic sorry to bust your bubble lol

That RPM optimism can explain a lot :-(
Btw, anyone knows how much optimistic the tachometer gets at high rpm's ?

I believe,it's like400-500rpms faster then the REAL RPM's

Keep in mind that there is tire slippage at high speed. You can NOT calculate speed according to a gearing calculator due to this. On top of that, as stated earlier, the tachometer is on the happy side.
Example:
ZX12R tach reads approx. 400-500rpm high
Gearing calculator states stock gearing on a ZX-12R is worth 203mph at 11.6k rpm, but due to tire slippage, they ALL hit the rev limiter at an actual 196-197mph on GPS......
Good luck with future runs, and ride safe.

Depends if you want to belive the tachometer but 10600rpm in 6th is actually about 175 mph (281 km/h) with standard 17/41 gearing, assuming no slippage.

Bob, r u sure that's the 6th gear speed ? Looks more like 5th gear....
I'll confirm tonight or tomorrow with GPS on... if weather permits !
Take care !

Black Shark, the 186 mph limiter is only for the US market, specifically to meet California's regulations (that's what my mechanic -who works in a Kawa dealer- says). Still though, I do remember that it was France the one who threat Kawa to include a speed limiter device or programming into their bikes, so maybe some European countries does receive speed limited units. The only limiter that all bikes have is the RPM limiter (as an engine protection system, so maybe this is the famous limitation everybody talks about).

No, that was for 6th gear but I was looking at the spreadsheet for the wrong bike. Doh.
Here it is, 10600 in 6th should be 200.5mph for a 14 running 17/41 final drive ratio.
However, if the bike is not derestricted it wouldn't rev past a TRUE 9800rpm in 6th which is 300km/h or 186mph. The top speed restriction is performed by the ecu. That could mean that the rev counter is several percent optimistic if it was reading 10600 on a restricted bike. I'm guessing you're derestricted if you're expecting 315km/h?
My experience is that the Tacho does over-read. For example it was reading about 11300 when I recorded a speed-trapped 203mph on 17/40 gearing. The actual rpm from the tables is more like 10500 running that final drive ratio. So it's around 7% optimistic. That figure does include any other kind of slippage too.
Let us know what the Sat Nav figure is.

bobc, with the speedo healer and stock gearing what would you say top speed would be if you had lots of room?

When I ran my bike stock with just a Speedo Healer in May 2006 it was speed trapped at 190mph on the 2 mile runway at Woodbridge. That's about 1.25 miles to accelerate.
My buddy Mike ran his bone stock 14, plus Speedo Healer, at the same runway in September 2006 when we had a really strong tail wind. He was trapped at 198.7mph and he said the engine rev-limiter had just cut in at the speed trap. So I guess if you have a hurricane up your butt then 198 is the theoretical maximum. The realistic maximum is more like 190 though.

Pedro, how are you getting on with the GPS?
I was doing some sums just now and realised that the 10600rpm, which you measured, minus 7% for the optimistic tachometer, by my reckoning, is 9858rpm. On my gear tables that's 186mph (300km/h) which is where the top speed limiter is. Just a coincidence?

Bob, we had rain all week, but forecast is better for sunday.
I hope it's true... it's really painfull staring at this beautifull bike stuck in the garage just after the running in had finished and real fun was about to start :-(
If forewcast is correct, I'll post the GPS measurements this sunday night.
A couple of questions (off topic, sorry)
How many rw bhp did your bike (or another ZZR1400), Full stock, in the same dyno you got those 192.9 ?
How many octanes has the fuel you use over there ? Under RON or MON measuring scale ?
Keep it flying !!!

I use ordinary pump gas, lead free 95 RON.
The stock 1400 was around 170bhp, so my bike gained over 20bhp from the pipe and pc with custom mapping. It's been over 200mph nine times now and best quarter, on stock wheelbase with 17/40 gearing, is 9.84sec at 142mph. That's with me riding and I make no claim to be good at quarters, it's about ten years since I've done any, just a great bike.

Am I correct to assume you gained around 15bhp or more from the exh pipe and the rest (if any) with the custom map ?
Those were the results (proportionally, not absolute) I got tuning my previous 2 bikes, a 2002 Suzuki gsx-r 1000 and the 2006 bmw K1200s. A lot from pipes, very little from custom mapping.
I did the mapping myself, first time with a PC, 2nd time (K1200s) direct in the original ECU. Both of them monitoring with external Lambda sensor and checking results at the dyno.
I tune and map road and race cars for a living for about ten years now.
(www.speed-factor.net)
I'm curious to see if the ZZR is the first bike where a good exhaust makes such a big difference as to justify significant fuelling changes from stock values...

Custom mapping is the way to go if you possibly can, although an off-the-shelf map will get you in the ball park. Your assumptions are correct.
This is how the dyno session went for my bike back in 2006:
Run number 2, all the modifications done (flies still in) and still running a zero map, gave 184.3bhp
Run number 18, with the custom map completed (flies still in), gave 192.9bhp
Custom mapping gave really good results lower down the curve with the secondary butterflys removed.
Before the remap but with flies out Torque was only 70 ft-lbs at 3000rpm and the power curve was wavy.
Run number 36, with the flies out and re-mapped, gave 80 ft-lbs Torque at 3000rpm with a flatter power curve.
As far as justifying significant changes from stock is concerned, the extra power gained, 8bhp, with the custom map could be the difference between my winning or losing.
