Top Speed by Gear Calculator​


Calculate your top speed in each gear based on
  • Engine RPM
  • Transmission Gear
  • Gear Ratio
  • Final Drive Gear Ratio
  • Tire size

We created an easy to use Excel / Google Spreadsheet:

Simply enter your tire size in the peach colored box (top left under Step 1) and your gear ratios in the blue (right under Step 2)

You will need to know your tire size and gear ratios to use the sheet.
