Over 6min of 200kph+ lane splitting

Matt - what you have to remember - is the 294 he recorded is an average speed over the 400m - whereby he is still accelerating through the trap and beyond given the run up is limited and has a bend. Try it on the back straight of Puke - 300kph is easy on a GSXR apparently - ask Kiwidan

It's OK wkid, I'm fully aware of the difference between average speed and terminal velocity. If your speedo is that accurate then congrads because you must have one of the best calibrated bike speedos in the country.

My point was that last year Tony was "averaging" 270 and while his terminal velocity would of been higher I doubt it would be over 280 (given it we're only talking around 5 seconds). So I am surprised (but pleased for you) that you hit 300 "real" kph, I suggest you make an attempt at the Land Speed Records before you sell the bike. I'd certainly have a go if I thought I could do it.

if people are regularly knocking the 300k door out the crate, then is 2ton the next barrier to come tumbling down? then what? some monstrosity of a bike breaks 350 out the box within the next 10 years? things are getting insane really quick.
riders never had it so good. any dickhead who knows how to twist a throttle can walk into a showroom now, hp up whatever shiny monster they like the look of, and do warp factor speeds in an instant, and at todays prices it's totally obtainable for a large number. i don't think there has ever been a time where there have been so many machines capable of ridiculous speeds on our roads and yet the roads have hardly changed. it's kind of an exciting time watching these 'hyper sports bikes evolve'. oh to be a good rider & confidently take charge of these monsters.
one day roger, one day 8-)

My old iron Sporty had the Yankee speedo that only went up to 80mph (REAL miles, none of this kilo-whatsit stuff) I believe it was a US Government ordered thing back then, the idea was that when doing 60mph on a 80mph speedo it meant the needle was 3/4 of the way round the dial, psychs you into believing you are going faster than you really are - it was a fuel crisis era idea.

The good thing was I could honestly say I didn't know its top speed, just "off the clock man, way off the clock"

Scary really 750.....I wonder how long it will be before they manu impose a voluntary governor/limiter on the speed achieveable. When you consider the new R1 is coming out with 180hp (with ramair) - terminal velocity is just a matter of how you want to gear the bike.

Yeah, I had a speedo like that once...

WKID, Manufacturers already agreed 2 years back to limit max speed to 186 mph (why 186 I don't know). Guess as soon as some manufacturer breaks this then they will all start pushing for fastest production bike once more. Doesn't stop you tuning it for more of course. So all bikes produced in the last 2 years have been tuned (eletronically limited?) to 299 kmh out of the crate as a max.

Yup, I recall reading in a road test comparison of the ZX12R and the '03 busa that the '12 just *stopped* at 186 with a few grand left in top gear and the busa did much the same, even though the dyno run indicated that the Suzuki had more ponies than the 01/02 model which did about 190-something stock. I think that's how it went anyway.

Here's an acrticle from 2000 about the Hayabusa and one about the Manufacturers Agreeing to voluntary speed restrictions.

Do you grippers have any idea how much horsepower it takes to make a 180kg motorcycle go 300km/h?

Obviously not - now I think I hear your Mummy calling...

Well that would also depend on the frontal area and coefficient of drag Oscar. That's why v twins can run similar speeds to in i4 with less power output. It's why unfaired muscle bikes go slower than min crotch rockets.

As for WKID...well looking 2 km ahead (2 km + straights?) AND reading the speedo at 300kmh. What can I say 83 metres a second whizzing by as he views his speedo.

Yup, I think the equation goes summat like, after 200mph, the average sports bike needs on average another 8hp for each additional 1 mph in speed....

...which roughly means that yer 150hp R1 will do 180ish mph on a good day, but you need a 240hp Ducati GP bike to crack the 200-210mph...

**bluninja** · 4th December 2003, 09:47

Not to mention the increase in forces on the tyres that could make the bead break or the tyre break apart...ooops I said not to mention that

well I guess there's no danger of the 350 mark ever becoming a reality with the current combustion design. maybe we just accept that 300k is plenty. I'd like to experience 300k at least once but in reality i probably couldn't appreciate it anyway.
