What is pitch of sprocket?

Pitch represents the amount of pitch diameter in inches per tooth. Sprockets with a larger pitch will have bigger teeth. Common pitches are 0.25”, known as #25, and 0.375” (#35).

What sprocket is best for speed?

For more top end and faster top speed, use a large countershaft/front sprocket or smaller rear sprocket. This creates a taller gearing ratio that’s best for high speed situations without many tight turns like wide open desert racing.

How do you calculate sprocket modules?

The value of the module is determined by calculating the material resistance in relation to the force to be transmitted and the gear ratio. Two mating gears must have the same module: m = d/z. Pitch Diameter (d) is the diameter of the pitch circle; its value is: d = m x z.
