Japanese bikes after 1995 with 180km/h speed limit?

[p.dath]

I was talking to someone today and they told me that Japanese bikes manufactured after 1995 have either speed or rev limiters fitted. Can't say I have owned a bike that "new".

But please, tell me this is not the case! Surely they don't fit speed limiters on bikes now?

[Mully]

Mine goes faster than that.

On a closed road of course.

EDIT: maybe Japanese domestic models....... Used imports.

[2wheeldrifter]

No not true....

[Pussy]

That will be Japanese domestic market bikes

[p.dath]

That will be Japanese domestic market bikes

Forgive my ignorance, what does that actually mean? Bikes that aren't intended to be exported?

[crazyhorse]

I've had 296 km/hr out of mine so far - so no idea what planet you've come from or the experience you've had when you were there LOL

[AllanB]

Japanese domestic market ones.

However some brand spanking new in NZ did have - my GS1200ss had a 180km limiter and the digital speedo stopped at 180. I'd imagine it was a easy task to have the limiter 'corrected' ...:whistle:

[Mully]

Bikes sold new in Japan - many have a limiter.

Cars were the same - gentleman's agreement to limit the power.

I am so impressed that stock GSXR can almost hit 300kph.

Maybe it is just NZ 'cos most people I knew in the UK with big Jap bikes had to spend a couple of hundred getting them derestricted.

[Blackshear]

My 1990 must have one of these black magics installed.
Can't get her past 169 indicated :baby:

Yep, the GS1200ss was a Japanese domestic market model... and AFAIK it isn't difficult to derestrict them

[Elysium]

I think this has to do with the likes of the Haybusa and Kawasaki 1200s being too powerful and they decided to limit their speed to 300km/h. This sounds right?

Not sure why you are surprised - it gets there really easily. Leaves alot of 1000cc bikes behind.

yeah, I think you are right - I have heard they have limiters at 300.

Yet strangely..the newer the jap cars we got the more power they made on the dyno. It was a load of crap, I've seen standard r23 gt-rs do 184awkw, around the same as a vt2 clubsport. Naughty japs lie about a few things, for our own benefit mind you. Calculated crank power on a standard evo 5 [or 6 I can't remember] was 312hp/230ishkw
Cbr250rr from [august?] 1993 had a 180kmh governor in them. Some do, some don't.

[ducatilover]

yeah, I think you are right - I have heard they have limiters at 300.

189mph....:rolleyes: Silly really, the advancements in highest bike speed would only be in very small increments

[Marmoot]

Japanese cars are restricted to 180kph and 280bhp by voluntary agreement between the Japanese car makers.

Bikes were not. But there are bikes which got the power output restricted (e.g., NSR250)

The cars did not necessarily adhere to those rules though. Thankfully the only real 280hp later model ones were jdm and aus evolutions and supras. Our jza80 got around 243kw from memory:drool:

I am surprised because I thought they were restricted to 250kph.

[swbarnett]

My 1984 CB750F2 was a Jap import (bought new). It was speed limited to 180kph. I don't think it's a new thing.

[Taz]

I bought a 1991 VFR750 jap import many moons ago, it had the 180km/h speedo and would not pull past that. I opened up the speedo and relocated the "trigger". speedo still stopped at the stop but bike kept pulling towards the mid 200's. You couldn't just unplug the trigger as it would affect the ignition and the bike wouldn't rev out.

[SARGE]

my 92 FJ1200 came from Japan restricted to 180.. the restriction fell off soon after i got it home though

They go nice with a 4 into 1 and a jet kit :devil2: lots of torque and plenty up top. I'm just to much of a feather weight to ride one, so a zzr600 is a reasonable compromise :banana:

they go even better with a big bore stroker, set of cams and stage 3 head ..


or so i've heard...:devil2:

[DMNTD]

As people have already mentioned it was the Jap imported bikes only(maybe a couple of exceptions).
Re the ZX14's...our has had its speedo reading approximately where 340kmph would be. Reading being the operative word. I'd say you'd have to take a good 10% off that

Correcto mundo. It is only a voluntary restriction so some are indeed not subjected to this. Especially true for export models.

Nice to see another supra. My jza80 is 280rwkw :Pokey:
But that's after I did what Mr. Toyoda has always intended.

I would love a jza80....a jza70 would be nice if done right, but not a ma, or ga70 ewww. 280rwkw would be a nice happy figure that is low [ish] boost and bugger all lag. What have you got done to her?

decat, fmic, fuel controller.

In bike language, it is a bit like a full system exhaust, K&N air filter, and power commander :)

The good ole 2jz frees up very nicely doesn't it? You should push a sub 12.4 on very good rubber and nice track with that kind of poke

As the thread says, it's limited to 180kph :laugh:

13 flat then....:nono:

[Big Dog]

yeah, I think you are right - I have heard they have limiters at 300.
I believe the "voluntary limit on jappa's is 186mph. Good luck finding out if you have a limiter.

This is normally either a carb "limitation" or a setting in the fuel injection..

That's european carmakers.

[ducatilover]

That's european carmakers.

The hayayayayayabusbusa and zzr1400 are both limited in jap land to 186mph. But for other domestic markets I am not too sure

[zx rider]

The Jap bikes with restrictors have less letters and numbers in their vin no's.
They are usually restricted by the ignition to give a 'soft' cut that won't cause a crash.
My Kawasaki has it's full 17 character id :clap: ,but the strangled ones have 13 or 15 only.
Check with your bikes dealers to find out what the sales guys do to check over a bikes credentails. They can spot it straight away.

[swbarnett]

No...that was it's top speed....:rolleyes:
Not according to Bill Russell.

All bikes that are capable of doing it are limited to 300kmh. This was enforced and agreed buy the factories to ensure no govt restrictions were placed on performance.
Jap market only 250cc bikes are limited to 180kmh. However as most 250's here are used jap market imports then the restiction is still there.
On the 250's there are ways around it. some are very simple (disconect a wire in the speedo) while others are more complicated ( requires entire new loom + bigger carbs)

[ozzkiwi]

Yep it is ture well here in aussie - is the Jap imports the confusing thing for me was when i had my Fj1200 and the bloke i knew had one he could not take her 170klph -hehehe mine was all good - first time up round 205kph and never again !!!!!!! scary stuff -tried it then dumped the throttle - there is a way is cancelling it - and its to do with two wires only(one is black) and i cant remeber what they were sorry :niceone:

Cheers Ozzkiwi

[wbks]

what the fuck... So it's ok to do three hundred fuckin k's, but not 320? :(

[pritch]

All bikes that are capable of doing it are limited to 300kmh. This was enforced and agreed by the factories to ensure no govt restrictions were placed on performance.


Exactly! This goes back to the days when there was a race between the factories to bring out the first production bike capable of 200MPH. Politicians worldwide started getting really twitchy about that idea.

If memory serves, the first model Hyabusa was faster than later models because of the voluntary restriction having been introduced. They and other subsequent models get there quicker, but 300kph stays the max.

Now if factories (MV?) start to break the agreement it'll be interesting to see what follows.

[george formby]

I have a Jap import which doe's not seem to be restricted or is de- restricted. Apparently, to derestrict it you have to replace the ECU with one from an export model. Owners of imports in the UK keep running into this problem. My speedo goes up to 180kmh but on a "closed, private road" will happily go off the clock before it runs out of puff. Not sure about other models or manufacturers but their is a load of info on t'web.

[awa355]

yeah, I think you are right - I have heard they have limiters at 300.

Way back in the early eighties a lot of big bikes had the speedo reading stopped at about 80mph ( 140 ks) . This was an American idea to make riders back off from riding too fast. The bikes went way past the final reading but the speedo stopped at the end of the dial.

[RDjase]

I've had 296 km/hr out of mine so far - so no idea what planet you've come from or the experience you've had when you were there LOL

:Oops:low gearing on that day mate? Its a flying 1/4 aye , not a kart/motard trak lol.

What are the ratios like on your bike if you put tall gearing on it? has it got close gearbox ratios and hard to get off the line with tall sprockets

Geared for about 200, if the fuel pump is running ;p First run was just mucking about and it completely died in the middle of the second.

Bugger, hate that, I did one years ago on my old road bike ,stock 1981 RD350LC, 179.8km.
good your out there and having a go safely and not just claiming what a speedo says:niceone:

crazyhorses bike is as fast as a 2008 hayabusa...........

[Drunken Monkey]

I believe the "voluntary limit on jappa's is 186mph. Good luck finding out if you have a limiter.

This is normally either a carb "limitation" or a setting in the fuel injection..

Yep, 186mph = 299km/h. Hit it almost every time around the kink at Pukekohe. The speedo shows 299 then the revs stop going up.

[avgas]

Carterton Flying 1/4 Mile (402 Meters)
Lets hope they have a spare couple of K's either end - Otherwise how can you achieve top speed?
My RG150 took about 2-3km to get to its top speed. Back in the days

[avgas]

( requires entire new loom + bigger carbs)
Errr no - you just punch the washers/restrictors our of the carbs and exhaust. If your are changing the carbs it would be suggested that the bike is deviating from non-standard......e.g. speed restrictions no longer applicable.

[Big Dog]

Yep, 186mph = 299km/h. Hit it almost every time around the kink at Pukekohe. The speedo shows 299 then the revs stop going up.
Yes the kink is good place to find out.
Almost anything finds out its max along there. Unless it is far from factory.
