JUST IN CASE YOU FORGOT
You can change it, thats the point of it. there are more <2008 than 2008's.I noticed the gearing is 17/40. That's the gearing for the Gen-1 Busa. The Gen-2 is 18/43.
assuming were talking about unrestricted motor, and that the chart is correct. Its lack of power.The thing that gets me is it shows that with stock gearing @ 10,800rpms you would be doing 201mph. Why doesn't that work in the real world ? I know that air drag and rolling resistance is a factor in getting that fast, but if your motor is showing 10,800 why won't the busa do it ? For the motor to be turning that fast it turns the gears a certain amount which turns the wheels a certain amount . So Then the only option is that the clutch would have to be slipping . The only reason I ask is because NO hayabusa with stock gearing has gone 201 with stock gearing even when topped out at 10,800 rpms . It always takes more HP and different gearing.
That is what I mean, even with 17/39 gearing you would not reach 200. With HP aside you would have made 10,800 and only been a couple MPH faster right ?I ran 17/39 at Bonneville and went 191.6MPH (top speed in Prod 1350 class). That was at 10,600 on the stock tach.
I was gaining about 200rpm (~1.5MPH) per mile traveled at the exit of the 5 mile.
Pat Womack was running 18/40 and was about 10,200-10,400 IIRC and maybe a half a MPH slower. (should have seen him screaming across the salt - very exciting!)
Reality is the difference. Its a straightforward calculation from engine rpm to gearing, just to give a baseline to work with. There is a lot of force back onto the bike at those speeds , so maybe clutch or tire slippage. Realize also, that 1" in tire circumference and 200 rpm off equates to 6+mph difference in calculation. Is the rpm gauge accurate or did the guy have the balls to get an accurate reading at speed?That is what I mean, even with 17/39 gearing you would not reach 200. With HP aside you would have made 10,800 and only been a couple MPH faster right ?I ran 17/39 at Bonneville and went 191.6MPH (top speed in Prod 1350 class). That was at 10,600 on the stock tach.

So how does a 17/40 gearing get you to 201? It doesn't , the graph is like a Suzuki speedo , OFF!
Don't get me wrong, I think its a kool site. I just mentioned that because I noticed this was placed in the '08 forum.You can change it, thats the point of it. there are more <2008 than 2008's.I noticed the gearing is 17/40. That's the gearing for the Gen-1 Busa. The Gen-2 is 18/43.
I made this page years ago, glad to see busa bothers still getting some use out of it.
From my understanding the reason is, just like the speedo is off, so is the tech.That is what I mean, even with 17/39 gearing you would not reach 200. With HP aside you would have made 10,800 and only been a couple MPH faster right ?I ran 17/39 at Bonneville and went 191.6MPH (top speed in Prod 1350 class). That was at 10,600 on the stock tach.
