This months feature is a downloadable Excel File for setting up gearing for a
Honda CR80 or CR125. There are 3 worksheets;

- Calculates RPM and MPH at shift points for up shift
The Ratio Chart is a no-brainer everyone has.
Select the CR125 Tab and you'll have the ability to see the big picture on
all the gears!
Enter the Tire Circumference, the Shift RPM, the Overrev RPM, the motor
Sprocket and the Axle Sprocket, and the chart calculates the speed of each shift
