CNC chain kit blue 420

CHOOSE your Transmission according to your desires


Mini MX proposes you to choose your transmission, choose more torque (Nervousness of the engine at low speed) or more length (Top speed) according to your Piloting.

This pack is composed:

- 1 Chain 420 (120 Links)

- 1 Sprocket 420 Number of teeth at choice YCF

- 1 Pinion 420, Number of teeth at choice, shaft of 17mm

The pinion shaft is 17mm, CHECK YOUR SPROCKET AXLE (See additional photo above)

Configuration advice:

In order to measure the power ratio, the calculation is done by dividing the number of teeth of your gearbox output pinion to that of your crown wheel:

Example: 13 teeth (pinion) / 39 teeth (crown wheel) = 0.33 gives you a configuration that accentuates the engine torque.

If you are close to 0.3 it increases the engine torque and close to 0.4 it increases the top speed. 0.34/0.35 is the middle ground between engine torque / top speed.

The engines mounted in 17mm shaft are:

125cc YX

140cc YX

150cc YX
160cc YX

107cc Lifan

88cc Lifan
