GEARBOX / DIFFERENTIAL / SPEED

 

     

The effective speed depends on tire size, differential, rotations per minute, gear and gearbox ratios.
How much exactly this effective speed is can be calculated here below.

Tire Size Height Perimeter
Standard / R cm cm
Differential : 1  
Rotations per minute rpm
Gearbox ratios Effective Speed
  1st : 1 km/h
2nd : 1 km/h
3rd : 1 km/h
4th : 1 km/h
5th / Rev : 1 km/h

This calculation uses the following formulas :
Perimeter = ((Tire width X Series / 100) X 2 + Rim size X 25,4) X Pi
Speed = ((Rotations per minute / Differential / Gear ratio) X (Perimeter / 100 X 60) / 1000
