Actual on the road would be about 184mph. Fine a good tuner in your area.

You guys are nuts! 2fast, thats one nice bike!
I would not mind being nutz myself if there were as good roads in India with low traffic... or some place like the saltsYou guys are nuts! 2fast, thats one nice bike!
The maximum I have gone on the roads here is about 140MPH
That bike kicks some serious a$$ but what the hell is wrong with your seat?? Ouchhttp://1st-to-the-finish-line.com
OK, OK...So I'm fatter than you thought, but I needs the weight for traction...
230MPH for Maxton in April is the goal.
Don't forget the $500 prize to whom ever breaks my record at the end of the season. Also receive $100 each event if you come within 5MPH of my record.

Like we care......
I have a 2002 with full Micron exhaust, PClll, BMC Filter, Ivans TRE, 6" over arm, 200lbs. I've maxed it out once and came very close several times. Does anybody know my approximate speed?

+1What? We are the ONLY 200 MPH people on this site!
I just assumed, after looking at LABUSAS that EVERY Hayabusa owner had been AT LEAST 200.Yhea if you believe what you read there we should all be doing 300mph by now.
2000 Busa, Muzzy Full Race Exhaust, TRE, K&N filter, airbox mod, Pair Valve mod....
Passed a pegged out '05 Gixxer k easy-like. I was buried to the bottom of the redline on 16-42 gears. Speedo indicated 220+ but with gears I figure it was about 189-190. Chain was loose so damaged my rear teeth.
Put stock rear teeth on (40) and buried it to bottom of the red. Pricing out 18 tooth front replacement to make sure I'm going over 200mph.
Oh... and am getting some of the other riders to laugh because I'm clover leafing low enough to scrape pegs on a semi-regular basis. Sounds like ripping paper when they drag.
I still suck at wheelies, though. Maybe a Gixxer K or 10R would be wiser for my style of riding. Anyway... peace to all.

16/42 gearing is worth roughly 173mph at the limter in 6th gear on the Busa...... nowhere near 180-190mph.
Stock gearing on the Busa allows for 196mph at the limiter.
Get a GPS and test it out..... factors like wheelspin and tire wear can effect speeds greatly. You can be hitting the limiter with 196mph worth of gearing and only be doing a true 192mph on GPS.

Btw... going 18/40 will give you roughly 208mph worth of gearing.... that's way more than your bike can hope to pull with the mods you listed... not only that, but the larger front sprocket adds more mechanical loss of power to the wheel.
17/40 (stock) is your best bet... If you can burry that.... go 17/39 and you SHOULD have 201mph worth of gearing.... but GPS will tell you what you're really doing at the limiter.

Our information seems to differ...
I have two RPM/REV printouts... one with a 16/40 (now), and the other with an 18/40 combo. Both assume a Measured Rolling Circumference of 77 inches, tire pressure at 40psi, a rear tire of 190/50-17 and a Primary Reduction Ratio of 1.59615 (stock - 52/83).
At 10700 in 6th, the Busa should be travelling at 187.4 mph.
With the 18 tooth, it should be travelling at 210.8 mph.
Limiting factors is not horsepower (that just determines how quickly it bangs through the gears), side and prevailing wind speed, and drag coefficient. If the wind is neglible and I'm using the 16 front and I'm at 10,800... I will be going 189.1 mph. Going up a tooth will take me longer to get through the gears, but my gears will be taller. With the 17/40 stock configuration I can go 200 mph if I'm willing to dip a little into the red (which I do routinely).
I'm planning to put the 18 on for next weekend and have a mount for a camera on my tank, so am planning on making a video... and have a friend with a Speedohealer I'm hoping to borrow. If all goes well, I'm certainly willing to share the vid. Luck to me.

Still need more HP and guts, 184mph is the fastest I've got her up too.
Yeah.... wish I had more horsepower too. I'm guessing I have about 169-171 at the rear wheel right now. Thinking of putting on a 40 shot for those "need to get going now" times, and lowering the rear by a couple of inches. Also, thinking of cutting my own seat to be more "Corbin"-like. Also, thinking of getting a better cam in it over the winter... not sure... might sell for GSXR1000 or ZX10R.

Egor- computer data and printouts are one thing..... the real world is another.
Does your formula compensate for wheelspin?
Does your formula compensate for clutch slippage?
On paper and In the real world are two different things...
Go out and try it with a GPS..... you'll see.

I agree. There is a difference. Of course it doesn't account for tire slippage, but that's a factor at 20mph as much as 200mph. Once you're up to speed, unless there's a sudden traction-control issue, it's a minimal concern. For my purposes, the biggest limiting factor is not the engine or gears, it's the drag coefficient and the amount of cavitating that will occur the faster you go. I find no noticeable issue until I hit about 180-185 and then the amount of turbulence (sp?) grows increasingly violent. At about 194-195 (the fastest I've had my bike up to), my head does shake a fair bit, but I'm still going those speeds. The biggest issue isn't getting up to speed, it's controlling the airodynamics and wind resistant forces that are telling me to shut it down. However, at a given RPM, given my bike... in a given gear, the rapidity of the wheels (negating whatever wheelspin urges there are), the bike will be travelling at a given, predictable speed.... It's basic mechanics. The main resistant to the speed you attain is your willingness to risk the shaking at high speeds and your primary and secondary reduction ratios. Given the primary reduction ratio of 1.596 and the 18/40 gearing, it will go a certain speed at a certain rpm (if you get to it). If you're in 6th and there's sufficient wind preventing you going over say... 9000 rpm's, you'll only manage 177.3 mph. That means the wind is stopping you, not the bike.
