I managed to scuff up some info, but personally, I can only tell you that second gear, I can get to around 110km/h.
here are some info...
Gear Ratios (Thanks Will
)
1st 3.505
2nd 1.904
3rd 1.310
4th 0.969
5th 0.815
final drive 3.526
[I]Engine RPM from Road Speed
To determine the proper engine rpm at a given speed, you may use the following system. If everything is correct, and the clutch is not slipping, you should be able to arrive at a fairly accurate figure.
1) Find the number of revolutions the rear tire makes in one mile. To do this, divide the circumference of the tire in inches by 12. This will give you the circumference in feet, plus, probably, a decimal fraction.
2) Divide 5280 by the tire circumference in feet.
3) Now multiply this figure by the final drive ratio. If the final drive ratio is 3:1, multiply by 3, etc. This will give the number of revolutions the transmission output shaft turns in one mile.
4) Multiply the result by the gear ratio of the gear you are in. For example, if you are in 6th gear and 6th is .88:1, multiply by .88. This gives the number of revolutions the transmission input shaft turns in one mile.
5) Multiply this result by the primary drive ratio. This will give the engine revolutions per mile in that gear.
6) Multiply this result by the number of miles you will travel in one hour.
7) Divide this result by 60. This will give you the engine rpm at that speed and gear combination.
The figures below show how this works on a KZ440, with a 130/90x16 rear tire. (The tire circumference is an approximation; to do this exactly you will need to actually measure a tire.)
