Gear/RPM/Speed Calculator
I just asked this question, then did research. How to you calculate your speed, RPM when changing sprockets.
Here is great link:
http://www.bikerenews.com/Stories_Archives/GearRpmSpeedCalculator.htm
You will need this info for a ZX14:
Primary reduction ratio:1.541 (94/61)
Gear ratios:
1st:2.625 (42/16)
2nd:1.947 (37/19)
3rd:1.545 (34/22)
4th:1.333 (32/24)
5th:1.154 (30/26)
6th:1.036 (29/28)
Final reduction ratio:2.412 (41/17)
Now, all you have to do is change sprocket sizes and you get the info you need for street or strip.

Yep, with gearingcommander you don't need the ratios as it already has them. Makes it easier to find the gearing you need for any bike.
