This sprocket is one of a wide range that we sell which fit Chinese petrolscooters and Mini Moto dirt bikes. Buyers will receive one sprocket as pictured. Sprockets do not come with mounting nuts or bolts, unless they are otherwise pictured. Please measure your old sprocket prior to purchase to ensure you order the right type for your machine. Things to check are the width, outer diameter, diameter of the central hole, and the distance between the fixing holes; measuring centre of eye to centre of eye. Sprockets come in a number of sizes, according to the type of chain they fit. You will need to choose the same size as you have already or your chain wont fit correctly.

Replacing your existing sprocket with one that has a different number of teeth will affect how fast your machine will go and how fast it will accelerate; this is called gearing.

Here are the rules of gearing

Increase the number of teeth on the DRIVE sprocket and you will increase the top speed but reduce the acceleration.

Decrease the number of teeth on the DRIVE sprocket and you will increase the acceleration but decrease the top speed.

Increase the number of teeth on the DRIVEN sprocket and you will increase the acceleration but decrease the top speed.

Decrease the number of teeth on the DRIVEN sprocket and you will increase the top speed but decrease the acceleration.

When changing sprockets just bear in mind you may need a larger or smaller chain.
