Hayabusa genuine top speed?

[avgas]

Dunno about the Busa - I got told it was the first bike to exceed 300kph.
I recall also that it beat the Blackbird (its direct competition) which only scraped the 200mph.

The blackbird and the Jag XJ220 did a shootout many moons ago (96?), and it was found the XJ220 could hit 220mph but the problem was there was no flat space on the planet where it would get past 198mph. Where as the Blackbird could scrape pass 201mph.

In 2008 I did a few runs at a timed flying 1/4 mile event on a 2004 busa with pipes, power commander and filter. Stock gearing. I was 88kg in my gear at that time.

At a whisker off redline in top (11,000) it was indicating between 340 and 350. Actual speed was 299kmh if I recall correctly. May have been 297.

Paul Hinton from Alexandra also did a 299kmh flying quater on a 2004 Busa. Sounds like he had the same setup as yours with power commander etc. He was gutted that a kwaka clocked 301 kmh.

Seems the new model is stronger again, with now 197hp.

at those kind of speeds, surely the aerodynamics tell more than the outright horseponies

Reasonably sure the Bird can't/couldn't hit 200mph...? They only poked out about 135-140 at the wheel.

200mph is 322km/h.

Has anyone worked out mathematically, the top speed at max revs?

I don't know the gearing ratio or the formula to work it out.

Gearing Commander suggests 324km/h at 11000rpm in 6th which sounds about right.

[JimO]

Ghost rider (or whatever his name is/was) was getting 299kph out of his all the time...

and that was in 1st gear

Which would indicate this bike was derestricted. Are they still restricting them at the factory or have they stopped the "gentleman's agreement"?

I'm pretty sure they're still restricting them. There'd be way more hype around bikes like the new ZZR14 being released if there was a "Fastest Production Bike" crown available.

That's what I thought. I saw another video where the BMW S1000RR won a top speed test. I thought it was dumb to even try it if the Busa and 14 were restricted...

[sinned]

I understand the limiter is at 299 on all except the first ones produced. Never seen that speed myself except on a train - evidenced by 298km/hr on GPS.

no speedo error here....

My understanding of the "gentleman's agreement" was more that they would no longer actively advertise theirs as being the fastest, and would start limiting the readout of the speedo, not the actual performance.

Doesnt make a whole lot of financial sense to build an engine on a performance vehicle, then choke the fuckin thing half to death before selling it. It would be more economical to simply build it to a lower spec in the first place.

My sentiments, too. While I may never ride at full speed, it is simply the principle of it. I just don't think any vehicle should be artificially restricted.
