should be good for 180-190 on the speedo.... 180 if it is still restricted....

I have only got up to about $1.80, at about 18,000rpm, in fith gear. And it still was accelerating slowly.
It was paying more attention to the road than my gauges thou.

yeah maybe you should check your bank balanace next time aye :whistle:

The fastest i ever took mine was 160kph but i wasnt trying to go as fast as i could, it didnt take that long to get there either, so I'd reckon you could get 200+ if you are light, and on a long straight

Nah mate, youll be lucky getting 190kmh (indicated) and most likely 180kmh actual..... Especially considering that a ZXR400 only does around 230kmh..... (that includes an extra 20hp over the CBR)

Hahaha i got $1.93-$195 (off the clock) so yes it is possible but then again i don't weigh that much

Rumour has it that a ZXR250 dropped from a helicopter at a height of 2000 metres will achieve approximately 210 km/hr (60 metres/second), or terminal velocity, shortly before it reaches terminal impact. :pinch:

Hey, its Friday... what else did you expect?

(Thank you Lagavulin 16 for that little bit of inspiration...)

Got up to $1.90 and it was still accelerating.

Speed limiter check = negative

mine was bouncing off the rev limiter in 6th gear at Pukekohe on the back straight during most laps showing around 190 but as thats the end of the line for standard gearing and the speedo (which would be lying anyway) its probably all you'll get provided you're properly tucked away behind the screen.
I would think 190 actual speed is realistic given optomistic speedos and hitting the limiter (mmm 18000rpm!) if you added a tooth to the rear sprocket because it didn't have much more to give.

I also have got $1.90 from mine, was trying to keep up with a VTR1000, then had to brake.
On a totaly un related topic, northern motorway before Silverdale is quite long and straight.

I don't disagree with you about the speed but what do you mean "hitting the limiter (mmm 18000rpm!)" , you are talking about the rev limiter right? and isn't it it limited at 21000rpm. It does run out of guts after 18000 but it red lines at 19000, or did you just miss type?

(look at the wiring diagram a can't even find a rev limiter, I hope its not the vavles bouncing)

185 on the clock normally. Hit a definite speed limiter at 190 ish when slipstreaming another bike.

now that you mention it, I think it cuts out at 19000. I had enough room at Puke to get it bouncing off there twice (ie. hit limit, decell, accel, hit limit again) on a run so I guess there's enough left to really hit 190 with re-gearing

I guess the CBR would acheive similar speeds?

Occasionally, when I have nailed it out of a corner in first or second I have had it bouncing off either the rev limited or valve bouncing. Obviously I wasn't paying attention to the tacho so I not postive what rmp I was doing, and I'm not keen to test it on purpose.

I was wondering if it does have a rev limiter?

I guess the rpm was about 21000, but I'm not 100% certain.

i've decided to "street-fighter" my zxr for the short-medium term until i can be bothered financing full fairing respray etc.

i will be dropping into atomic on thursday (payday) for indicators and mirrors, then all it will need is a chain, a key for the tank and seat, carb service, VIN/REGO/WOF.... nearly there :2thumbsup

Hi guys, im new here, also new to owning a bike with gears, suppose my streetmagic didn't really count as a bike !
Anyway, from my understanding these bikes are limited to the same speed as any jap car (185) unless you have a deristrictor as I do on mine.
I haven't gone anywhere near this and don't really intend to either, but it just looks like the little white box and it changes the signal from the speedo when in top gear.

I got about 170 km/h out of one at Manfield (indicated) but I'm pretty fat and I was missing most of the fairings. That's a standard 'A' model, 'cept for the pipe.

The 'c' models are a bit slower, I've heard.

I got the Team MILF ZXR250 up to 180down the back straight of Puke without hitting the limiter.

Here are the results from the last 1/4 mile sprints.

http://www.cdd.co.nz/sprint/EastWestSprintResultsNov2005.htm

The ZXR250 was hitting the speed limiter so couldn't get max revs. The CBR250 wasn't been ridden to redline as its done 153000kms! but still managed reasonable times.

Doesn't the 'C' model ZXR have a few more hp than the 'A' model?

wow didnt think think our speeds were that close. Time for a few mods i think. Would have been good if they posted the standing 1/4 times aswell.

If I remember correctly (don't quote me though :) ) the 1992 and after models were restricted by HP somehow.

93 on, derestriction involves a trip on the speedo ON BOTH THE ZXR AND CBR.

I'd like to run the standing quarter myself, I am abit warey of the validity of that comparision on that site of the CBR/ZXR

*delayed response*

I've taken mine up to 170kph on that last ride I went on up to Wellsford... Don't know if I could have pushed it further, but found by the time I got to 170 it was time to slow down for thw twisties...

while we're on the subject of kwaka's, which is faster, the zzr250 or the gpx250? i know they have the same engine, but there are a fair few design differences, so yeah, does anyone know?

I was under the impression the zzr was heavier, but more powerful (relatively hehehehe)

Tippity top speed is 160 for a zzr250. That was slightly downhill too...

err... On a racetrack :wari:

you tell me for a gpx... for acceleration, I would have no idea

17th December 2005, 13:32
I've only taken my ZXR to 180kph but it still had a bit more punch left - I would have known is true top speed if not for the shit weather today on the way to Puke :pinch:

i got my fzr250r upto 185 in 6th at 17000still had a bit left reckon it would pull 190

Dyno'd to 204, off the clock at 190, shift into 6th and it still goes a bit more... who knows. I should put my push bike speedo on it and calibrate it and really see what it can do...

slopster
18th December 2005, 17:50
Borrow a handheld gps unit that will give an accurate speed reading - but beware that you will be dissapointed with the results because the speedos are rounder uppish. My old zxr 250 maxed out at 173km by gps and that was off the clock.

Agree with the Dyno readout for the back wheel, I've also had the same result.
The actual speed on the road, I think you'll struggle to get to that especially with drag and everything, not to mention the speedo governor.

I was very impressed with the accuracy of the CBR s speedo...it was pretty much the same as the quarter mile times. Mind you the speedo cable is run off the front sprocket of the cbr.
Next time I think I'll run it to redline in 5th then change to 6th - with a bit of tail wind that may push into the 190km/hrs :ride:
