Gear Ratio Calculation

WARNING: This page is about a different variant/trim than selected.

Example:

Example:	5th Gear	Final Drive
Drive gear	ZG₁ = 37	ZA₁ = 14
Driven gear	ZG₂ = 50	ZG₂ = 69
*) Z₁ = Number of teeth on the drive gear, Z ₂ = Number of teeth on the driven gear

i_G = gear ratio = ZG ₂ : ZG ₁ = 37 : 50 = 0.740

i_A = axle ratio = ZA ₂ : ZA ₁ = 69 : 14 = 4.929

i_total = total ratio = i_G x i_A = 0.740 x 4.929 = 3.647

Z₁ = Number of teeth on the drive gear, Z ₂ = Number of teeth on the driven gear
