EVM-0426G Motor sprockets comparison set

This set of sprockets allows you and the students to perform comparison test runs to understand and confirm the difference between the gains in torque and speed using different gear ratios.

It  includes (2) 10-tooth motor sprockets and (2)14-tooth motor sprockets; using them in combination with the original 12-tooth sprockets in your vehicle, it provides a full range of power-to-weigh comparison.

10t(motor) to 72t(axle) = 7.2 to 1 ratio

12t(motor) to 72t(axle) = 6  to 1 ratio.

14t(motor) to 72t(axle) = 5.14 to 1 ratio.
