Hayabusa genuine top speed?

[Edbear]

My thoughts exactly.
I reckon 200 on a blackbird was impossible - not due to HP.....but if the factory claims 178mph......good luck in getting past 190.

And if it could....then how does busa breaking 300kph fit in?

There are lots of figures, but few facts.

Ironically, in that article with the bbird and the XJ220......the jag didn't break 200mph and that cars supposed top speed was over 220mph!

The Bird was good for just a tad over 170. There are a few Blackbird owners on this forum.

Well the rev counter was on 11,000, so I would expect that to be reasonably accurate and this is the stock gearing from the spec sheet...

The original '99 unrestricted version with 155hp was clocked at Avalon airstrip in Aus at 311km/h, the '08 onwards versions have 175hp. This partiucular bike must have been deresricted from the 186mph limiter.

200mph is 322km/h.



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

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

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.

Latest bikes have 197hp, so the 320km/h mark is achievable without restrictions.

I know the TL1000R has a soft limiter removal mod to give an extra 500rpm.
This may be the 5th gear mod which would then in fact remove retard if it thought it was always in 5th.

Pretty sure its not the TRE mod, which is something else and would only give a SV650 a few extra hp not even 97hp let alone the obvious typo of 197hp.

I found my TL had its clutch interlock defeated (no need 4 clutch for starter), This makes the bike use a slightly different fuel map reducing output torque

With NOS, sure

With NOS, sure

According to the calculations, 11,000rpm in 6th gear equates to 324km/h, so assuming the rev counter is correct this bike was doing that speed stock.

Mmmmmhmmmmmmm

Do you account for wheel slippage?
Gearing commander says 324.1km/h at 11,000rpm and that sure looks like gearing that has been made the perfect length for the bike.

Surely someone can pull a decent test out?

So Malcom Beadmore or whatever his name is, wasted all that money on NOS, only to go 318 (back in 2008 i think) when we saw him at carterton sprints?

somebody should have just told him to twist the throttle abit more.

And those fags that bored their ones out

There were differences in hp output over the years, the opriginal had 155hp, then it went up to 175hp and the latest has 197hp. Remember in '99 they had to increase hp to 200 to reach the 320km/h mark and got 311km/h stock at Avalon airfield. So it depends on what his was putting out originally and then of course the conditions of the time have a lot to do with it, i.e. wind, gradient, air-flow, etc.

Witness the problems they still have at Bonneville to break the 200mph mark on the salt.

197 rear wheel hp? The original was 155 at the wheel, I thought the current model had about 175rwhp? 197 is madness....

[Edbear]

Interesting vid and shows that on the road, there is precious little difference that can be measured. The ZX12 deserved a much better record than it got, just because it failed to top the Busa. It's a great bike in its own right.

197 at the crank currently, so not sure about RWHP I'll see if I can find a dyno test.

I'd say 175-180 at the wheel would be realistic, as I said the original were around 155hp at the wheel as compared to 140ish at the rubber on a Blackbird.

I really want to see a test on the new 'Bus sounds like a mental bit of kit

One of the sad things about my current situation is that I'll never get to ride one, now.
