it wasnt falling off a cliff was it??

Terminal Velocity for any falling object is 260km/h i think, so rules that theory out.

thats only on "restricted" terminal velocity..u need that "unrestricted" terminal velocity, prior to 2000....

well how do i unrestrict the terminal velocity on my bike? ( im not throwing it off a cliff either)

oh its the 2000 gentlemans rule...

bit of an in joke round here, that a few of the boys have "unrestricted" 12's...hahah

Dependent on aerodynamic properties of the object. A 50kg sandbag thrown from aplane will reach a lower terminal velocity than, say, a small aerial bomb because the bomb is more streamlined.

so if i put a 50kg bag of sand on the back and ride it off a cliff i should be able to get past that f**king limiter

yep for sure but you wont live to tell the tale

There is one other not often spoken way to boldly go where no resticted bike has been before.. If you hum " Go speedracer go go speedracer go speedracer go go speedracer " over and over again you will break that speed barrier but be warned you seldom return !

do i need to be looking in the mirror when im chanting or just head down arse up and screaming it as i hit the limiter

I didnt think 12's WERE restricted.
My 05 has got a different front sprocket so it is going slower than the speedo says again, BUT the bike doesnt know that.
As far as IT is concerned it is on the stop which would be over 320 9as far it is concerned).
I know this to be true because I have seen it myself and it was STILL accelerating (remember it has a different sprocket).
NOT some dealer BS but with my own eyes.
It has PCIII but the ignition is still the same and that would be where the restrictor is surely.
What gives ??

definitely - the earlier ones (2000-2002?) did not have a limiter in the ignition system - they could freely rev out to a *supposed* top speed of about 320 ? Fastest speed obtained by AMCN in 2001 at an airstrip in Vic was 304 measured by radar, so that would be an accurate measurement - and also account for the speedo error at top end.

From the 2003 or 2004 model, they had a restrictor built into the ignition system, which cuts the spark at a pre-determined point when the CPU recognises both 6th gear and 11,000 rpm on the tacho. This is meant to be a limit of 299kmh, same as current ZX14 and Busa's from about 2002 ?

It can be easily by-passed with a timing retard eliminator (TRE), which just fools the CPU into thinking that the bike is in 5th gear not top, and allows full ignition in top gear.

Any bike showing 300kmh on the speedo *will not* be doing 300kmh, its that simple. Most speedos have an error factor of anywhere between 2 and 10% - less error at lower speeds. Faster you go, higher the error factor becomes.

300 on the dial will anywhere between 270 and 285-290.

The only way to get an indicator of true top-speed is to be measured by an accurate radar, down an airstrip.

With a tooth down on the front sprocket, combined with the built in error, the 10 was out by approx 9-10% when checked against a GPS...only around 5% of that was the sprocket

how does the retard work? not to sure on all this restrictor stuff but i hit 300 on the speedo at about 10300/10400 Rpm and the speedo stops but the tacho will keep going to atleast 12000Rpm. If im revving 1500rpm above where i hit 300 how does it keep the bike from passing that speed?
