Hayabusa genuine top speed?

[Edbear]

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

That was the whole reason for the design of the bike in the beginning.

Here are some results from Cliff Hanger 1/4 mile flying sprint (about 2.2k run up) These are actual speeds, not speedo readings.

Dean Van Ingen 2005 Suzuki Hayabusa 1300 318.91
Daryl Archer 2008 Suzuki Hayabusa 1340 296.13
Stephen Rigg 2008 Suzuki Hyabusa 1340 293.50
Malcolm Breadmore 2006 Suzuki GSXR 1300 (N2O?) 313.57
Kevin Ure 2004 Suzuki Hayabusa 281.83
Martin Peck 2006 Suzuki Hayabusa 267.51
Peter Harkess 2004 Suzuki Hayabusa 293.87
Kevin Ure 2007 Suzuki B-King 1340 262.71
Dean Van Ingen 2005 Suzuki Hayabusa Turbo 314.06
Dean Veale 2000 Suzuki Hayabusa 1507cc 328.49
Malcolm Breadmore 2006 Suzuki Hayabusa (N2O?) 321.13

Brilliant! Thanks for that.

Worth noting the 3 busas pulling more than 300 actual were lowered and modified quite a lot

When it was tested at Avalon in Aus, back in '99, they had a performance centre increase power to 200ps in order to reach the 320km/h, (200mph), mark. The 311km/h speed was achieved on a stock bike.

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.

200mph and 300kph are different numbers.

Afaik, the Blackbird was the first "hyperbike" to use that term loosely and the first to break 300kph. The Busa was released the following year and took the title from the Blackbird, plus all the name games, where the Hayabusa is Japanese for a bird that hunts blackbirds...

Either way, boss has a Blackbird, my only speeding ticket was on it, I didn't even realise I was doing 136, and it's far too easy to do stupid speeds with minimal revs.

Scary bikes

I believe the Japanese are scrapping the "gentlemans agreement" next year.....so that what she does, is what she does - and fuck the Europeans!

i understand the restriction is a limit on the revs the bike can pull in top gear, this is easily over ridden by a small device that tricks the bike into thinking it is still only in fifth gear.

No restriction in first gear though , a Gen2 Busa's good for around 145 before the shift up to 2nd ...magic

It's a TRE (timing retard eliminator). Not sure if there are other restrictions on the 'busa.

I put a TRE on the SV650. It's amazing how it went from 74hp to 197hp with such as simple mod!

You missed the decimal point!

Hmmm with all due respect, i dont see how a device that controls the rev limit in top gear , and stops the ignition being retarded in lower gears (read as a poor mans traction control) can increase the horsepower of a bike??

You wanna buy a bridge? I got a goody!

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.

zx12 ran 305 there , mabe 2003?

[Brett]

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

That video has the worst voice over I have heard in a long time.

[avgas]

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

200mph is 322km/h.

200mph and 300kph are different numbers.

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

Some people here are so smart. Others need to read between the lines a bit.
The 3 points I made were
- Busa beat the blackbird
- Supposedly the Busa was first bike annouced to do past 300kph
- A test against an XJ220 showed the Blackbird did over 200mph

So which was fact?

4 more sleeps till the new 14 from Kawasaki is revealed on Oct 10.

Might change the playing field somewhat , I've heard 210 +hp and 1429 cc - mid nines out of the box . Plenty of stories going round and the big K is keeping this one pretty close to their chest ...

Can't wait and , I'm a 'Busa man but nothing wrong with a little competition
