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

[Grahameeboy]

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

No...that was it's top speed....

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

13 flat then....

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.

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

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 ,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.

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)

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

Cheers Ozzkiwi

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

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.
