Gear Ratio Speed Calculator for Standard Triumph Drivelines

The mintylamb.co.uk calculator is back!!!

Tyres
Gears
Final Drive

This page was inspired by the gear ratio calculator that James used to host on mintylamb.co.uk – for the time being it doesn’t take into account overdrive setups.

To use :

  1. Set your tyre Width, Aspect and Diameter (e.g. a 175/70R13 tyre would have a Width of 175, Aspect of 70 and a Diameter of 13).
  2. Select a gearbox (or enter your own values)
  3. Select a differential/final drive (or enter your own value) and a maximum RPM limit

The graph and max speed values should automatically update when you change any value.
