CALCULATION CHART OF CONVERSION RATIO "i" (EXAMPLE)

Gear	5th gear	Final drive
Drive gear	ZG1 = 51	ZA1 = 18
Driven gear	ZG2 = 38	ZA2 = 66

i =Z₂ /Z₂ =Number of teeth on driven gear/Number of teeth on drive gear

i_G = Gear ratio =ZG₂ /ZG₁ = 38/51 = 0.745

i_A = Final drive ratio = ZA₂ /ZA₁ = 68/18 = 3.667

i_Overall = Conversion ratio = i_G x I_A

i_Overall = 0.745 x 3.667 = 2.732
