<< It may be 242 as indicated by the speedo, but it's probably not more than 220... >>
How do you figure? And I don't think it matters that much, it's f*ckin fast none the less.

Well, now this is a thread I like 
Lemme see.. The dash looks like a 'Busa. Probably a 2000 or 2001 because 2002s had the speedo changed to 185 mph because of those damned EUROPEANS lol.
Mungla is right, bikes made after 2000 are restricted per EU orders to 300 kph which works out to 186 mph I believe. I have a '99, which is the first year of production and is the fastest of the bunch.(no restriction of course)
Pullmyfinger- You are correct as far as the bikes tested by the cycle mags. However there seems to be some variation in top end among these machines. I have hit 198 officially on a closed circuit but I have seen verified unmodded runs of 201 (rare though they be).
Motorcycles are notorious for the inaccuracy of their speedos above a certain speed. Busa riders generally figure that speeds are overstated by 5 percent over 150 or so.
The bike definitely had a turbo to get to that speed, but honestly I wondered if it was rigged to give an exaggerated reading. It just didn't look fast enough, but that was a long wheelie at pretty good speed, so it may have indeed been genuine. There are a few turbo bikes out there. I was reading in one mag recently that one companies turbo gives 325 hp at low boost, and pushing a button gives 375. What would bother me is tires. The busa can take that power without much problem. but I do not know if any tires can push 200+ for long.

<< It just didn't look fast enough >>
I agree. As one of the few people on this forum that actually ride a bike, now, today I can tell you that something is wrong with this video. OK, the bike is a turbo. It was not doing 220-240mph.
I have a 97 Katana 750. Jetted/full pipe/ignition advanced. But, a toy, compared to this bike. My speedo maxes at 160MPH, but I know motorcycle speedos are notoriously inaccurate, especially at higher MPHs
Judging by the VIPER that paced me on serveral occasions (my bud
), 160 on my bike's speedo is about 148-150mph. I have been that fast, on a regular basis. We have a road where I live, up in the hills, that is conducive to this kind of shenanigans. That's as fast as my bike will go.I've done 150 not once or twice but dozens of times. It's DAMN fast. The bike in this video was doing around 190MPH or so. I've ridden a 2000 Hayabusa. I got 185 on the speedo, which is around 175MPH, real world.
Can I prove it? No. But I'm judging by how fast the scenery was flying by. I can't account for the diff b/t the speedo and the scenery...but I know what I know. That's it.

<< Hayabusa rider, do you have any pics of your bike? >>
Not until I can figure out how to get my old umax scanner to work with xp GRRRRRRRR
Anyway it is a black/gray. There was that and the silver/copper in 99. Didn't like that combo for some reason.
<< The video I posted of the GSXR 600 seemed faster than that busa video too, and I'm pretty sure that one didn't get up to 240... >>
I thought the same thing.
Hayabusarider,
Maybe you could help us out here. Assuming that the bike in the video has stock gearing, what will a Hayabusa pull at 11k rpm? Maybe you can check your bike and tell us what speed you get in top gear at say 3k -5k rpm, we can then scale that up to 11k rpm. To those that are asking why gearing is important, the reason that gearing is important is becuase the speedometer pickup on many newer bikes is no longer located on the front wheel, it's on the output shaft of the tranny. That's why the speedo kept climbing even though the front wheel was off the ground. Thus, if you change your gearing or tire OD, your speedometer will be off, just like in a car. If the bike in the video has lower gearing (smaller countershaft sprocket or larger rear sprocket) then the speedo will read high by the ratio of old drive gearing to new drive gearing.
As far as the video "looking" a certain speed, that's questionable, there's no way to determine a vehicle's speed based on how fast it "looks" but there are indicators in the scenery. About a third of the way through the video, the rider passes the entrance to a road on the left, which seems to creep by. The white lines in the road however, continue to zip along at a pretty good pace, odd.

<FONT face=Verdana>It's a stock 1999 Haybusa with the 1998 220 MPH speedo, and it hasn't been calibrated properly, the 220 is actualy 185. Someone on the Haybusa forums did the math and in 6th gear at the RPMs he was showing he was actually doing about 196 MPH. Still fast as hell, but not the 240 or so that was indicated. He has a plug or something that he can pull to just let the speedo show false, he did it for the video to make it more dramatic.

considering the tach climbed another 1000 rpms (about 10%) after the speedometer topped out, he probably was doing about 230-240.
tooo fast for me...i don't even want to think about it.

Your disbelief is understandable, and perhaps even justified. BUT it is very likely that the rider was in fact going 220+.
Judging speed from a video like this is very tricky. Your perception of speed is determined in part by the rate of flow in the visual field. Flow in the visual field is dependent on the relative motion of the perceiver and the distance between the perceiver and the corresponding point in space of the visual field. Objects far from the perceiver and along the path of motion will move very little, whereas objects close to the perceiver and off the path of motion will move very quickly. The camera acts as a filter to the visual field, cropping the very near ground where scenery would be blurred b/c it is going by so fast. The camera had also been aim almost directly down the line of motion so that the viewer of the video is in fact only seeing the slowest part of the visual field.
"He has a plug or something that he can pull to just let the speedo show false, he did it for the video to make it more dramatic"
That bastard!
Nice trick.

Pullmyfinger, Be glad to do this, though it will probably be next tuesday. I have to go out of town Friday and the weather sux here the next 2 days. The weather in Feburary in the Boston area is fickle. .I can't remember precisely what rpm matches what mph, but i'll get the readings for 3, 4, and 5k in 5th and 6th (cuz I didnt count his shifts, and some guys stay in 5th unless they have to shift).

Hey guys, I finally got to go for a little bit of a ride, but traffic was SOOOOO slow, that I got only one useful reading- 3000 rpm in 6th = 58 mph. There was so much traffic that I could only go this fast for an instant, so figure +/- 3 mph error since I could just glance at the speedo.

The more I look at the vid, the more I think it is about 160 mph or so. He's not really moving that fast.
