MPH with Gear Changes

[Corso1]

All-

I haven't the cash to get a Speedohealer right now. I was wandering if anyone might happen to know what the actual speed vs indicated is on a Busa once the gearing is changed to 16/42.

Any ideas? All replies are appreciated.

Thanks-

With stock gears the speedo is off about 7%....16/42 and your off by about 18%. Tire wear can also throw it off a little more. With it off 18%.....100MPH indicated would actually be 82MPH

I might be interested in the speedo healer group buy too. I don't like guessing my speed.

You will be off by about 14%  Stock is off by 7%  18/40 is off by about 2% 19/41 is right on the money.

I thought stock gearing was off 7% at low speed and high speed @12%-13%

 

[frisbee]

percentage's don't change with speed , just gearing.

I thought 18/40 was much accurate...... saw that somewhere at the other forum.
